I'm working on interfacing a PLC to an existing machine that's

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.

Similar in concept to this?

Yes, similar in concept (I spent three years at a job using those identical socket savers - brings back memories) but entirely the wrong socket. Also, the probe tabs would need screw terminals. But yes, this is the right (sort of) idea.
