The V23 is a surface / wall and 35 mm rail mount D-Relay Socket. The V23 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.
The V23 relay socket has no internal soldering 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.
Clear UP arrow for correct 35 mm rail mounting.
