Pilz PNOZ s10 Safety Relay Contact Expansion Module 773810

The Pilz 773810 (PNOZ s10) is a contact expansion module designed for use within the PNOZsigma family of safety relays. It functions as an instantaneous contact expander in safety-related control circuits, allowing users to increase the number of available safety contacts when connected to a base safety relay or safety controller. Equipped with four normally open safety contacts and one normally closed auxiliary contact, the unit operates on a 24 V DC supply voltage. The module features plug-in screw terminals for straightforward electrical wiring and maintenance, alongside diagnostic status LEDs that provide clear indication of operating state and switching positions. Engineered for mounting on standard 35 mm DIN rails, the compact housing ensures minimal space utilization inside industrial control cabinets. The device is commonly deployed across automated production lines, packaging machinery, material handling systems, and assembly cells to safely switch actuators, contactors, and motors in emergency stop and protective guard monitoring applications.
