CS AR-02ME02 Pizzato Safety module 3NO, category 4

CSAR-02ME02 Safety Relay Module Overview

The Pizzato CSAR-02ME02 is a safety relay module from the CS AR series, designed for monitoring safety functions such as emergency stop circuits, safety gate switches, and interlocking devices in industrial machinery.

It belongs to the CS AR-02 family, which typically provides a 3NO safety output configuration, making it suitable for applications that require multiple safety contactors or parallel safety outputs in machine control systems.

Main Function

• Monitoring of safety gates and interlock switches
• Emergency stop (E-stop) circuit supervision
• Safe shutdown of industrial machinery
• Driving multiple safety contactors via redundant outputs

Key Features

• Supply voltage: 24 Vac/dc
• Safety outputs: 3 NO (CS AR-02 family standard)
• Safety level: Category 4 / PL e / SIL 3
• Function: Dual-channel safety monitoring for guards and E-stops
• Mounting: DIN rail (22.5 mm compact housing)
• Connection: Plug-in screw or spring terminals (variant dependent)

Safety Performance

The CSAR-02ME02 is designed for high-risk industrial machinery and complies with:

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

This ensures redundant internal safety architecture and safe failure behavior, 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

• Machine guarding systems
• Industrial automation lines
• Robotics and conveyor systems
• Packaging machinery
• General industrial safety circuits

Quick Summary

The CSAR-02ME02 is a 24V AC/DC safety relay module with a 3NO output configuration, used in Category 4 / PL e / SIL 3 safety systems to ensure reliable machine shutdown in hazardous conditions.
