Socket with relay, DC 24 V, 2 changeover contacts
788-312
1
Relay socket for DIN 35 carrier rails.
Status indication through pluggable LED module (red).
Insulated, pluggable jumper system suitable for both coil
and load side.
CAGE CLAMP S connection.
Solid wires, fine-stranded wires with crimped ferrules or
ultrasonically bonded wire ends can be inserted directly.
Quick exchange of the relay and the status indication
during maintenance, without having to detach the wiring.
Safe electrical isolation in accordance with DIN VDE 0140
