ZJ157F slim interface relays

The ZJ157F is a slim plug-in interface relay for PLC I/O and control panels, made in 1-pole and 2-pole versions with silver-alloy contacts. Four build levels share the same electrical data, so you can add an LED, a lockable test button or a cover without changing the socket.

Matching 157F relay sockets

ZJ157F relays plug into 157F sockets. Choose the socket by wiring method first, then by pole count: 1P relays use the 1Z (1CO) sockets and 2P relays use the 2Z (2CO) sockets.
