KSR-25 Contact Guard Relay

The task of the KSR-25 Contact Guard Relay is to unload and galvanically separate weak current and low voltage contacts, e.g., reed contacts and contact meters. Depending on the wiring, the unit operates in bistable or monostable mode and as a contact follower. Simultaneous the switching state is saved remanently. It is also retained in case of supply voltage failure. State of readiness and switching status at the input terminals are indicated by LEDs.
