Product Description
PiLZ S4 751104 750104 Safety Relays
The Pilz PNOZ s4 (750104) and PNOZ s4 C (751104) are standalone safety relays designed for monitoring E-STOP pushbuttons, safety gates, and light barriers. The primary difference between the two is their terminal type: the 750104 uses screw terminals, while the 751104 features plug-in spring-loaded terminals for faster, tool-free wiring.
Key Features & Functions
- Operating Modes: Configurable via a rotary switch on the front panel, supporting manual start, automatic start, and monitored start with a startup test.
- Input Monitoring: Supports 1-channel or 2-channel wiring with optional detection of shorts across contacts.
- Outputs:
- 3 N/O: Safety contacts (instantaneous) for safe power interruption
- 1 N/C: Auxiliary contact typically used for signaling status to a PLC
- 1 SC: Semiconductor output for additional diagnostics
- Safety Standards: Meets high safety requirements (up to PLe/Category 4), featuring redundant built-in self-monitoring and automatic contact testing in each cycle.
