PILZ PNOZ S4 751104 750104 SAFETY RELAY
Product Overview

The primary difference between the two models is their connection technology:

  • 751104: Equipped with spring-loaded (cage) terminals for tool-free wiring
  • 750104: Equipped with screw terminals for traditional wiring
Key Technical Specifications

Both models share the same core technical features:

Feature Specification

Series PNOZsigma (PNOZ s4)
Mounting DIN rail
Safety Outputs 3 N/O (normally open), instantaneous
Auxiliary Output 1 N/C (normally closed)
Signal Output 1 semiconductor (24 V DC / 20 mA)
Number of Inputs 3 (for dual-channel safety circuits)
Safety Category Up to Category 4 / PL e / SIL CL 3
Contact Rating 6 A (at 240 V AC or 24 V DC)
Dimensions (H x W x D) 100 x 22.5 x 120 mm
Operating Temp. -10°C to +55°C
Detailed Features
  • Self-Monitoring & Redundancy: The unit has a redundant internal circuit with built-in self-monitoring. The safety function remains effective even if a component fails.
  • Operating Modes: The operating mode (e.g., automatic start, manual/monitored start) can be configured via a rotary switch on the device.
  • Status Indication: Six LED indicators on the front panel show the status of Power, Inputs, Outputs, Reset, and Faults for easy diagnostics.
  • Safety Standards: It complies with major international standards including EN 60947-5-1, EN 60204-1, and VDE 0113-1.
Summary of Differences: 751104 vs 750104
Feature 751104 750104
Electrical Connection Spring-loaded (Cage) terminals Screw terminals
Wire Stripping Length 9 mm 8 mm
Wire Range 0.2 - 2.5 mm² (24 - 12 AWG) 0.25 - 2.5 mm² (24 - 12 AWG)
Torque Not Applicable 0.5 Nm
