The V93 is a surface / wall and 35 mm rail mount D-relay socket. The V93 socket has one screw terminal per relay contact suitable for two wires upto 2.5 mm2 , so looping/daisy chaining can be done on the socket and no external connector or terminal is needed.
The V93 relay socket has no internal connections which makes it highly reliable. To prevent fault relay placement the socket can be equipped with mechanical keying to accept only designated identical keyed relays.
