The Pilz PNOZ S7 751107 is a high-integrity contact expansion module from the PNOZsigma family of safety relays. It is specifically designed to increase the number of available safety contacts when connected to a base safety relay unit. This compact module provides four normally open (N/O) safety contacts and one normally closed (N/C) auxiliary contact, enabling the safe and simultaneous switching of multiple circuits. With its narrow 17.5 mm width, it is an ideal space-saving solution for control cabinets. The PNOZ S7 ensures reliable expansion of safety functions for applications requiring a higher number of safety outputs, such as emergency stop circuits, safety gates, and light curtains.
