CS AR-04M024 Pizzato Safety module 3NO+1NC, category 4

CSAR-04M024 Safety Relay Module Overview

The Pizzato CSAR-04M024 is a safety relay module from the CS AR series, designed for monitoring emergency stop circuits, safety gate switches, and interlocking devices in industrial machinery.

It belongs to the CS AR-04 family, which is typically used in applications requiring an expanded safety output configuration for controlling multiple contactors or safety zones in complex machines.

Main Function

• Monitoring of safety guard doors and interlock switches
• Emergency stop (E-stop) circuit supervision
• Safe shutdown of industrial machinery
• Control of multiple safety contactors or safety zones

Key Features

• Supply voltage: 24 Vac/dc
• Safety outputs: Expanded output configuration (CS AR-04 family, multi-output safety relay design)
• Safety level: Category 4 / PL e / SIL 3
• Function: Dual-channel safety monitoring for E-stop and guard devices
• Mounting: DIN rail (compact 22.5 mm housing)
• Connection: Plug-in screw or spring terminals (variant dependent)

Safety Performance

The CSAR-04M024 is designed for high-risk machinery safety systems and complies with:

• EN ISO 13849-1 (Category 4 / PL e)
• IEC 61508 (SIL 3)

This ensures redundant internal safety architecture, where any detected fault forces the system into a safe state.

How It Works (Simple Explanation)

• Door opens → machine stops immediately
• Emergency stop pressed → power is safely cut
• Fault detected → system transitions to safe state

Typical Applications

• Complex machine guarding systems
• Multi-zone industrial automation systems
• Large production lines
• Robotics and conveyor safety systems
• Packaging and processing machinery

Quick Summary

The CSAR-04M024 is a 24 Vac/dc safety relay module from the CS AR-04 family, designed for multi-output safety applications requiring Category 4 / PL e / SIL 3 protection in complex industrial machinery.
