PILZ 750104 SAFETY RELAY PNOZ S4 24VDC 3n/o 1n/c 750104

Description:

The PILZ 750104 PNOZ S4 24VDC 3 N/O 1 N/C Safety Relay is used in industrial safety control systems to monitor emergency stop circuits, safety gates, and protective devices while providing controlled safety output switching. Commonly installed in machine safety panels, control cabinets, and automated production systems where reliable safety logic evaluation and safe machine shutdown are required. Safety engineers, maintenance teams, and system integrators use this relay for safety circuit upgrades, retrofit installations, replacement of failed safety relays, and compliance with machine safety standards.

Applications:

The PILZ PNOZ S4 safety relay is commonly used in manufacturing production lines, robotic workcells, packaging machinery, press lines, material handling systems, and guarded machine enclosures where monitored dual-channel safety inputs and controlled stop outputs protect personnel and reduce operational risk.
