The V12 is a surface / wall mount relay socket. The V12 socket has one screw terminal per relay contact suitable for two wires up to 2.5 mm2, so looping/daisy chaining can be done on the socket and no external connector or terminal is needed.

To prevent fault relay placement the socket can be equipped with mechanical keying to accept only designated identical keyed relays.
