Siemens LZS Series Coupling Relay, Plug In, 110V dc Coil, 4PDT

The Siemens Plug-in relay complete unit module red Socket with logic isolation Spring-type terminal. It has 2 changeover contacts. The coupling relays with semiconductor output have low power consumption and are therefore particularly well-suited to solid-state systems. In the versions equipped with LEDs, these indicate the switching state. Coupling relays have a test button. This can be used to force the relays into the switching state and to lock it without electrical control. This is indicated by a raised petrol-colored lever.
