Pilz PNOZ po3 Safety Relays 2p 4n/o (773631) is a safety relay designed to monitor safety circuits and control multiple output channels through four normally open contacts. It is used in industrial systems requiring higher switching capacity and simultaneous control of multiple safety-related outputs.
What is Pilz PNOZ po3 Safety Relays 2p 4n/o (773631)
This relay is typically used where multiple actuators, contactors, or control points must be managed within a single safety circuit. The 2-channel input structure supports dual-channel safety monitoring, while the four normally open outputs allow distribution of safety signals across several devices.
Unlike basic safety relays, this model is suited for applications where load distribution and output redundancy are important. It helps reduce the need for additional expansion modules by providing multiple outputs within a single unit.
