Or, is there another similarly low cost and simple solution you’d recommend?\n \n The circuit runs on 12VDC from a [Mean Well IRM-10-12 ([specification](https://www.meanwellusa.com/webapp/product/search.aspx?prod=IRM-10)), and the relays I have on hand are OMRON G5LE-14-CF 12VDC ([specification](https://omronfs.omron.com/en_US/ecb/products/pdf/en-g5le.pdf)).

Toggling a single relay hasn’t caused me any issues in the limited testing I’ve done. A momentary drop to as low as 5V should be perfectly fine, although, looking over the specs for my components, I see I’m getting dangerously close to the upper limits for the power supply’s current rating. I’ll have to look into connecting 2 supplies in parallel (or getting a larger supply) I suppose.\n \n I haven’t worked with battery backups yet, so I was thinking it would be best to keep that element simple to minimize potential issues like a trickle charge draining the battery unexpectedly, or damaging the battery from overcharge. The minimum requirement is just to ensure the hardware (a motorized ball valve) returns to a closed position if power is lost.

The only specification I see on the datasheet for coil amperage is that it was tested to failure at 100mA.

Toggling a single relay hasn’t caused me any issues in the limited testing I’ve done. A momentary drop to as low as 5V should be perfectly fine, although, looking over the specs for my components, I see I’m getting dangerously close to the upper limits for the power supply’s current rating. I’ll have to look into connecting 2 supplies in parallel (or getting a larger supply) I suppose.\n \n I haven’t worked with battery backups yet, so I was thinking it would be best to keep that element simple to minimize potential issues like a trickle charge draining the battery unexpectedly, or damaging the battery from overcharge. The minimum requirement is just to ensure the hardware (a motorized ball valve) returns to a closed position if power is lost. The battery needs to provide at least 9V to power the motor, so I could use a 9V (or a few smaller cells in series) to keep it below the 12V supply.\n \n With your solution using a diode on each voltage source, would there be any risk of a trickle charge draining the battery unexpectedly if the battery? If so, in that configuration I’d need to do more research and figure out how to use a BMS, rather than an externally recharged or disposable cell.

Or, is there another similarly low cost and simple solution you’d recommend?\n \n The circuit runs on 12VDC from a [Mean Well IRM-10-12 ([specification](https://www.meanwellusa.com/webapp/product/search.aspx?prod=IRM-10)), and the relays I have on hand are OMRON G5LE-14-CF 12VDC ([specification](https://omronfs.omron.com/en_US/ecb/products/pdf/en-g5le.pdf)).

have a circuit that will need to return connected hardware to a default state if power is lost.

Toggling a single relay hasn’t caused me any issues in the limited testing I’ve done. A momentary drop to as low as 5V should be perfectly fine, although, looking over the specs for my components, I see I’m getting dangerously close to the upper limits for the power supply’s current rating. I’ll have to look into connecting 2 supplies in parallel (or getting a larger supply) I suppose.\n \n I haven’t worked with battery backups yet, so I was thinking it would be best to keep that element simple to minimize potential issues like a trickle charge draining the battery unexpectedly, or damaging the battery from overcharge. The minimum requirement is just to ensure the hardware (a motorized ball valve) returns to a closed position if power is lost.

have a circuit that will need to return connected hardware to a default state if power is lost. The hardware can handle continuous voltage, so I’m thinking a simple solution would be to use a battery to provide that fallback power source. To avoid draining the battery, I’d like to connect it through a relay on the normally open contact and energize the relay directly from the main power supply on my board.\n \n Do I need to look for anything in particular to make sure the coil on the relay I choose can sustain constant voltage for potentially months at a time without damage? Or, is there another similarly low cost and simple solution you’d recommend?\n \n The circuit runs on 12VDC from a [Mean Well IRM-10-12 ([specification](https://www.meanwellusa.com/webapp/product/search.aspx?prod=IRM-10)), and the relays I have on hand are OMRON G5LE-14-CF 12VDC ([specification](https://omronfs.omron.com/en_US/ecb/products/pdf/en-g5le.pdf)).

have a circuit that will need to return connected hardware to a default state if power is lost. The hardware can handle continuous voltage, so I’m thinking a simple solution would be to use a battery to provide that fallback power source. To avoid draining the battery, I’d like to connect it through a relay on the normally open contact and energize the relay directly from the main power supply on my board.\n \n Do I need to look for anything in particular to make sure the coil on the relay I choose can sustain constant voltage for potentially months at a time without damage? Or, is there another similarly low cost and simple solution you’d recommend?\n \n The circuit runs on 12VDC from a [Mean Well IRM-10-12 ([specification](https://www.meanwellusa.com/webapp/product/search.aspx?prod=IRM-10)), and the relays I have on hand are OMRON G5LE-14-CF 12VDC ([specification](https://omronfs.omron.com/en_US/ecb/products/pdf/en-g5le.pdf)).

have a circuit that will need to return connected hardware to a default state if power is lost. The hardware can handle continuous voltage, so I’m thinking a simple solution would be to use a battery to provide that fallback power source. To avoid draining the battery, I’d like to connect it through a relay on the normally open contact and energize the relay directly from the main power supply on my board.\n \n Do I need to look for anything in particular to make sure the coil on the relay I choose can sustain constant voltage for potentially months at a time without damage? Or, is there another similarly low cost and simple solution you’d recommend?\n \n The circuit runs on 12VDC from a [Mean Well IRM-10-12 ([specification](https://www.meanwellusa.com/webapp/product/search.aspx?prod=IRM-10)), and the relays I have on hand are OMRON G5LE-14-CF 12VDC ([specification](https://omronfs.omron.com/en_US/ecb/products/pdf/en-g5le.pdf)).

have a circuit that will need to return connected hardware to a default state if power is lost. The hardware can handle continuous voltage, so I’m thinking a simple solution would be to use a battery to provide that fallback power source. To avoid draining the battery, I’d like to connect it through a relay on the normally open contact and energize the relay directly from the main power supply on my board.\n \n Do I need to look for anything in particular to make sure the coil on the relay I choose can sustain constant voltage for potentially months at a time without damage? Or, is there another similarly low cost and simple solution you’d recommend?\n \n The circuit runs on 12VDC from a [Mean Well IRM-10-12 ([specification](https://www.meanwellusa.com/webapp/product/search.aspx?prod=IRM-10)), and the relays I have on hand are OMRON G5LE-14-CF 12VDC ([specification](https://omronfs.omron.com/en_US/ecb/products/pdf/en-g5le.pdf)).

The minimum requirement is just to ensure the hardware (a motorized ball valve) returns to a closed position if power is lost. The battery needs to provide at least 9V to power the motor, so I could use a 9V (or a few smaller cells in series) to keep it below the 12V supply.\n \n With your solution using a diode on each voltage source, would there be any risk of a trickle charge draining the battery unexpectedly if the battery?

have a circuit that will need to return connected hardware to a default state if power is lost. The hardware can handle continuous voltage, so I’m thinking a simple solution would be to use a battery to provide that fallback power source.

Or, is there another similarly low cost and simple solution you’d recommend?\n \n The circuit runs on 12VDC from a [Mean Well IRM-10-12 ([specification](https://www.meanwellusa.com/webapp/product/search.aspx?prod=IRM-10)), and the relays I have on hand are OMRON G5LE-14-CF 12VDC ([specification](https://omronfs.omron.com/en_US/ecb/products/pdf/en-g5le.pdf)).

Toggling a single relay hasn’t caused me any issues in the limited testing I’ve done. A momentary drop to as low as 5V should be perfectly fine, although, looking over the specs for my components, I see I’m getting dangerously close to the upper limits for the power supply’s current rating. I’ll have to look into connecting 2 supplies in parallel (or getting a larger supply) I suppose.\n \n I haven’t worked with battery backups yet, so I was thinking it would be best to keep that element simple to minimize potential issues like a trickle charge draining the battery unexpectedly, or damaging the battery from overcharge. The minimum requirement is just to ensure the hardware (a motorized ball valve) returns to a closed position if power is lost. The battery needs to provide at least 9V to power the motor, so I could use a 9V (or a few smaller cells in series) to keep it below the 12V supply.\n \n With your solution using a diode on each voltage source, would there be any risk of a trickle charge draining the battery unexpectedly if the battery? If so, in that configuration I’d need to do more research and figure out how to use a BMS, rather than an externally recharged or disposable cell.

Toggling a single relay hasn’t caused me any issues in the limited testing I’ve done. A momentary drop to as low as 5V should be perfectly fine, although, looking over the specs for my components, I see I’m getting dangerously close to the upper limits for the power supply’s current rating. I’ll have to look into connecting 2 supplies in parallel (or getting a larger supply) I suppose.\n \n I haven’t worked with battery backups yet, so I was thinking it would be best to keep that element simple to minimize potential issues like a trickle charge draining the battery unexpectedly, or damaging the battery from overcharge. The minimum requirement is just to ensure the hardware (a motorized ball valve) returns to a closed position if power is lost. The battery needs to provide at least 9V to power the motor, so I could use a 9V (or a few smaller cells in series) to keep it below the 12V supply.\n \n With your solution using a diode on each voltage source, would there be any risk of a trickle charge draining the battery unexpectedly if the battery? If so, in that configuration I’d need to do more research and figure out how to use a BMS, rather than an externally recharged or disposable cell.

Or, is there another similarly low cost and simple solution you’d recommend?\n \n The circuit runs on 12VDC from a [Mean Well IRM-10-12 ([specification](https://www.meanwellusa.com/webapp/product/search.aspx?prod=IRM-10)), and the relays I have on hand are OMRON G5LE-14-CF 12VDC ([specification](https://omronfs.omron.com/en_US/ecb/products/pdf/en-g5le.pdf)).

Toggling a single relay hasn’t caused me any issues in the limited testing I’ve done. A momentary drop to as low as 5V should be perfectly fine, although, looking over the specs for my components, I see I’m getting dangerously close to the upper limits for the power supply’s current rating. I’ll have to look into connecting 2 supplies in parallel (or getting a larger supply) I suppose.\n \n I haven’t worked with battery backups yet, so I was thinking it would be best to keep that element simple to minimize potential issues like a trickle charge draining the battery unexpectedly, or damaging the battery from overcharge. The minimum requirement is just to ensure the hardware (a motorized ball valve) returns to a closed position if power is lost. The battery needs to provide at least 9V to power the motor, so I could use a 9V (or a few smaller cells in series) to keep it below the 12V supply.\n \n With your solution using a diode on each voltage source, would there be any risk of a trickle charge draining the battery unexpectedly if the battery? If so, in that configuration I’d need to do more research and figure out how to use a BMS, rather than an externally recharged or disposable cell.

have a circuit that will need to return connected hardware to a default state if power is lost. The hardware can handle continuous voltage, so I’m thinking a simple solution would be to use a battery to provide that fallback power source. To avoid draining the battery, I’d like to connect it through a relay on the normally open contact and energize the relay directly from the main power supply on my board.\n \n Do I need to look for anything in particular to make sure the coil on the relay I choose can sustain constant voltage for potentially months at a time without damage? Or, is there another similarly low cost and simple solution you’d recommend?\n \n The circuit runs on 12VDC from a [Mean Well IRM-10-12 ([specification](https://www.meanwellusa.com/webapp/product/search.aspx?prod=IRM-10)), and the relays I have on hand are OMRON G5LE-14-CF 12VDC ([specification](https://omronfs.omron.com/en_US/ecb/products/pdf/en-g5le.pdf)).

Toggling a single relay hasn’t caused me any issues in the limited testing I’ve done. A momentary drop to as low as 5V should be perfectly fine, although, looking over the specs for my components, I see I’m getting dangerously close to the upper limits for the power supply’s current rating. I’ll have to look into connecting 2 supplies in parallel (or getting a larger supply) I suppose.\n \n I haven’t worked with battery backups yet, so I was thinking it would be best to keep that element simple to minimize potential issues like a trickle charge draining the battery unexpectedly, or damaging the battery from overcharge. The minimum requirement is just to ensure the hardware (a motorized ball valve) returns to a closed position if power is lost. The battery needs to provide at least 9V to power the motor, so I could use a 9V (or a few smaller cells in series) to keep it below the 12V supply.\n \n With your solution using a diode on each voltage source, would there be any risk of a trickle charge draining the battery unexpectedly if the battery? If so, in that configuration I’d need to do more research and figure out how to use a BMS, rather than an externally recharged or disposable cell.

Toggling a single relay hasn’t caused me any issues in the limited testing I’ve done. A momentary drop to as low as 5V should be perfectly fine, although, looking over the specs for my components, I see I’m getting dangerously close to the upper limits for the power supply’s current rating. I’ll have to look into connecting 2 supplies in parallel (or getting a larger supply) I suppose.\n \n I haven’t worked with battery backups yet, so I was thinking it would be best to keep that element simple to minimize potential issues like a trickle charge draining the battery unexpectedly, or damaging the battery from overcharge. The minimum requirement is just to ensure the hardware (a motorized ball valve) returns to a closed position if power is lost. The battery needs to provide at least 9V to power the motor, so I could use a 9V (or a few smaller cells in series) to keep it below the 12V supply.\n \n With your solution using a diode on each voltage source, would there be any risk of a trickle charge draining the battery unexpectedly if the battery? If so, in that configuration I’d need to do more research and figure out how to use a BMS, rather than an externally recharged or disposable cell.
