## Description

10 amp SPDT, 10-30 VAC/DC/120 VAC coil, sold as each, Functional Devices RIBU1C enclosed pilot relay, 10 amp SPDT with 10-30 VAC/DC/120 VAC coil. Made in United States. Manufactured by Functional Devices, Inc.

Review: RIB Relays - Work as they should. Saved a lot of time not having to purchase at the supply house.
Review: NICE PRODUCT - This device works as advertised. I use it on a 12V fridge that has an AC powered electronic temp control. When I turn off my inverter the device shuts off and routes 12V power to fridge and simultaneously disconnects my temp control loop so the fridge keeps running. Turn the ac back on and temp control is restored with no interruption in cooling (except the contents of fridge are colder) . The device, when on, runs very cool, it is quiet when functioning. Wiring diagram was easy to interpret. The body of the unit is pretty tough. I like the post and nut mounting style as this makes it useable as an add on to existing circuits. Indicator light tells you when AC is present and unit is on in the mode that you wired it for.

### ⭐⭐⭐⭐⭐ This solved a problem with our pool light
*by T***R on February 22, 2020*

We have a rental property with a small pool that has an RGB pool light powered by 12VAC. The light has several colorful programs consisting of different colors, even programs that cycle through several colors. Very ugly. We just wanted a white light. The problem is, you select programs by cycling the on-off switch N times until you get to the program or color you want. This being a rental property, tenants are often fiddling with the light switches to figure out which controls what, and pretty soon the pool lite is cycling through some ugly sequence of green or purple or something. We also have LED landscape lights that turn on at dusk, off at dawn. There is enough hysteresis in the photocell circuit that the lights cleanly turn on once at dusk, then turn off at dawn. Perfect for turning the pool light on and off without inadvertently changing its program. The only problem is, the landscape lights are 12VDC, but the pool light is 12VAC. So we couldn't just wire the pool light to the landscape lights. This relay was the perfect solution. I connected the "input coil" to the 12VDC output of the landscape lights, and used the output relay to control the 120VAC side of the step-down transformer on the pool light. Voila! Each night the pool light comes on with the landscape lights, and goes off the next morning when they do. Since there's no flickering to fool the pool light into a different program, it reliably stays on the last program I set which was the "white" program. The relay even has the correct threads for a standard 1/2 inch electrical knockout. I just went to to the local "depot for homes" store and buy a cheap fitting to get a rubber washer and thrust nut to let me install the relay on the side of the transformer box for the pool light.
