I'm working on interfacing a PLC to an existing machine that's full of relays. I got to thinking that it would be a real time saver if I had a relay breakout board of sorts. What I'm picturing is a relay base (in this case an 8 pin rectangular that plugs into an 11 pin socket) that breaks out into screw terminals.

The effect would be like piggybacking another socket on top of the original. That would allow pre-wiring a lot of stuff and minimizing downtime, as well as making the modifications easily reversible.

So, does such a device exist?

like this?

No, not like this. What you suggested is a relay socket - I really thought I had made it clear that I'm looking for something that will plug into an already existing relay socket, and bring the connections out to screw terminals.

For the third, fourth or fifth time: I work on lots of machines that have cabinets loaded with this sort of relay socket (with relays plugged in). I upgrade these machines by adding PLCs in place of the relays. It would be a good thing if I had the ability to just plug my wiring into the already existing relay sockets.

Therefore, I'm looking for either a male plug shaped like the relay base that would plug into the socket you linked to and provide a duplicate set of screw terminals; or even better, a socket with the female terminals (and screw terminals) on top and male terminals (like on a relay) on the bottom so that the device could plug int the existing socket , provide an extra set of screw terminals AND optionally have a relay plugged into it. So it sould sandwich between the original socket and the original relay.

I'm not sure how to describe it any more clearly.
