The model 750103 is a safety relay designed for monitoring emergency stop push buttons, safety doors, and light barriers. A contact expansion block PNOZsigma can be connected using a plug connector. The operating modes can be set via a rotary switch. The relay features LED indicators for supply voltage, input status of channel 1, input status of channel 2, switching status of channel 1/2, start circuit, and fault. Additionally, it offers pluggable terminal blocks (either spring-loaded terminals or screw terminals). Each on-off cycle automatically checks whether the relays of the safety device open and close correctly. The circuit is designed to be redundant with self-monitoring.
