Your cart is empty.The SSU-PAM-1 Relay provides 10.0 Amp Form C contacts. The relay may be energized by one of three (3) input voltages: 24VDC, 24VAC, or 120VAC.

Used this to automate the on and off of a VFD spindle on a CNC Router system. Took a bit to get it figured out. I used a switch 120v on the control module to active the relay.I had to edit my post processor to include a delay to allow the tool to come up to speed.Wiring was actually simple. White / black for the 120v in, then Blue and Orange for a N.O switch.I used a Huanyang VFD. Blue went to the DCM and Orange went to FOR. In the PID's had to switch pd001 from 0 to 1. This allowed input from the relay to activate the spindle.

Used with a Light-O-Rama control board to turn off the power to my Christmas display signs spot lights that are controlled by a background show sequence and not each song. Easy to hookup and works fine with 110v AC from a board channel to power the relay. Great small size compared to a small mechanical relay switch.

I bought one of these relays last year for my travel trailer. I use it to shut off the power converter when I turn on my inverter. Worked beautifully and highly recommend it. I sold my old trailer and bought a new one. I bought another relay even before I purchased an inverter to install in the new trailer. I do not want to rely on my memory to switch off the converter's breaker, so I wire the relay to switch off the converter whenever my inverter is powered on. No forgetting and ezy peezy.

Awesome little relay. I use them to automate low voltage components with off the shelf 120v smart controls. Used to add WiFi switch to control my fireplace from my iPhone.

You connect the two trigger wires to each other, and the relay toggles to its other state and stays. (Sort of like a flip-flop). I tried to drive the non-voltage trigger wire with a 5 VDC edge trigger, but it did not work. So you cannot trigger this relay with a logic rising or falling edge from some other circuit. Kind of a disappointment, but the relay itself is great. Now I just have to create a transistor or relay circuit from my logic board that will connect the two trigger wires together when I want it to trigger.

I was a bit skeptical of this little guy at first, but it proved me wrong! I use it to control my room humidifier. The coil is powered off a 20 VA transformer with 120VAC primary side and 24VAC secondary. The coil is wired in series with a humidistat. I used the NO contacts, and wired them to an outlet. I must say, not having to worry about humidity is a relief.Pros: this relay is very small, and fits inside a large junction box. Very easy to wire, the contacts are rated for 10A.Cons: the LED status light is bright (if needed for dark rooms) but can be fixed by placing it in either an enclosure or junction box.

I am using these with three wire White-Rodgers zone valves so I can connect the zone controls to two wire Nest thermostats. They have been working great and do exactly what we want them to do! Your Nest WILL work with a three wire system! (Just takes some time and figurin'....)

Used this with an Insteon Hub and Insteon On/Off module to control a fireplace so now I can have the Amazon Echo operate it. Would have used Insteon I/O device but it isn't supported on the Echo at this time. Placed the Ssd-Pam-1 in a one gang wall mount box wired to a 120v plug from an extension cord. It's more compact than the few 120v relays I could find and having the color coded wire leads made it easy to hook up. Having it encapsulated with no chance of spark is good too. HWorking well so far.
