Models of the PNOZsigma safety relay series range from S1 to S10, with the smallest relay measuring just 12.5 mm.

Models of the PNOZsigma safety relay series range from S1 to S10, with the smallest relay measuring just 12.5 mm. The units are capable of performing the functions of about 100 other relays, including safety-related functions such as E-Stop, safety gate, light curtain, or two-hand control on independent standalone machines.

The relays mount on DIN-mounting rails without tools. Removable wire connectors make reconnection a snap. When expansion units are needed, the relay’s innovative plug-in connectors require no wires.

Using operating-mode selector switches, users set the PNOZsigma to their own process and safety requirements, including operating modes, reset modes, time delays, and timer functions. With only a few knobs and switches, the relays can identify reduction, delay time, disconnect, or delay closure.
