thanks
 
It's a fairly generic older style open frame relay.

The contact ratings are: 1A 28V DC or 1A 120V AC
The nominal coil voltage is probably 5V, for the one you show.

There are some higher coil voltage ones on ebay at absolutely ludicrous prices, but a modern functional equivalent should be less than $10.
 
Thank you. The only thing thats missing for me is the coil voltage, it does say 2.3ma DC operate, but doesnt say voltage.
But there is a coil resistance of 1K, so Ohms law would indicate a voltage of 2.3 Volts.

But, since it list an operating current instead of a voltage, it might be intended for a non-standard application where the relay coil is in series with something else.
