Pinout or schematic of this big solid state relay

Hi,

I salvaged this part along with a huge amount of other parts from a commercial photocopier.

I did not found any datasheet and my supposition is that it is an AC relay driven by the 12 volts DC pins. There was a 120-60 sticker that I removes to read under so it should also work at 120volts/60Hz.

Unfortunately, the 12 volts pinout is not obvious. Not to me anyway.

How could I test this thing without risking to burn it?

Hi Alain,

if you salvaged that relay from the copier you certainly still have the connector for the 12V line somewhere in the machine. The pin labelling on the enclosure suggests pin1 as +12V and pin 5 as ground.

Looking at the connector it should only have two wires connected to it.

Hi,

Thanks for the idea. I found the connector. I should have think of that by myself! I am so dumb sometimes.

Anyway!

So this nice part happend to be a 3 in one SSR. 3 differents relays, the outputs controlled each one by the negative 12v wire applied to pin 2,3 or 4. Pin 5 is not connected.

I will certainly use it some day.
