Review: Works perfect - Works perfect...as long as you wire it correctly. Connect "com" and either NO or NC. It's a little annoying that the switching connector is stacked on top of the com. You have to connect the com first. Don't forget to add a diode to protect the coil. There is a good youtube video as to why it's a good idea..
Review: Does what it's supposed to, but lack of documentation is annoying - Relays in general can be confusing, but relays with no documentation just make it worse. While this appears to be made well and worked for what I bought it for, it sure was annoying having to puzzle through the terminals to figure out what's what. These don't appear to follow either NEMA or IEC relay numbering standards, and without instructions, you're on your own to test out the terminals. Thankfully the base is clearly marked, so that helped. My relay was supposedly a "24vac relay" but it appears to activate with either AC or DC power, I tried both successfully at 24 volts. If it helps anyone, here's the breakdown of an 8-pin: Pins 7 & 8 are your coil terminals, which activate the relay when power is applied to them. If AC is being used to activate the relay it doesn't matter, but if DC is activating the coil then pole 7 is negative and 8 is positive. Pins 1, 3, and 5 work together as a circuit. Pins 2, 4, and 6 work together as a circuit. The above is what makes this a "Dual Pole" (DP) relay - there are two independent poles where 1/3/5 (the terminals making up pole 1) do not touch terminals 2/4/6 (pole 2). You could use those two poles independently, such as to power two different devices requiring two different voltages, or you could use one pole as a power supply and the other as as a ground. There's a lot of options. Using just one pole as example, this is how the terminals can work: Pin 5 is incoming power that will be delivered to either pin 1 or pin 3, depending on if the relay is activated or not. It's labeled as "COM" because pins 1 and 3 have pin 5 in common. Pin 3 is "Normally Open", which means that when the relay is off/deactivated, there won't be any power supplied to pin 3 from pin 5. Power will only be applied to pin 3 when the relay is activated. Pin 1 is "Normally Closed" and works opposite of pin 3. When the relay is off/deactivated, there WILL be power supplied to pin 1 from pin 5. When the relay is activated, there will be no power to pin 1. Because the 1/3/5 circuit makes one circuit when it's powered and another when it's powered off, it's called a "Dual Throw" (DT). Combined together, this is a DPDT relay. Pins 2, 4, 6 work the same as the above. In my case, this relay was used to power a 120v outlet used to activate an outdoor fountain. A diagram is attached with details. I needed to be able to turn on this fountain two ways - either on a schedule from my smart home devices, or else manually via a hardware switch at the fountain. By utilizing the Dual Throw feature of the relay, I was able to accomplish this - when the relay is deactivated/off, power is supplied to the manual switch. When the relay is activated, power is killed to the manual switch.

## Questions & Answers

**Q: Am I correct in thinking that the 12v switch leads connect to 7 and 8 and the 120v leads connect to 3 and 4?**
A: The coil is on 7 & 8 it is 12v  This is your control or activation. 1,3,&5 are one set of contact for loads with 3 being common, 1 being normally closed and 5 being normally open. 2,4,&6 is another set of contacts with 4 as common , 2 nc and 6 no. The contacts are rated for 10 amps

**Q: Does the base accept ring terminals?**
A: No because the screws are captive and I don't see any way to remove without cutting a lot of black plastic off. Would have to split the rings or use Y-terminals.

**Q: What is the pu. Current and do. Current**
A: pu current = pickup current (current must go above this value to turn the relay ON)
do current = dropout current (current must drop below this value to turn the relay OFF)

**Q: Since there are 2 normally open and closed contacts can this handle breaking 10 amps 24vDc on both normally closed contacts?**
A: Yes but you should run it at 80% like all switxhed

This is a great little relay. Hookup is straightforward, just follow the schematic and use a VOM to confirm connections.
