CS AR-02M120 Pizzato Safety module 3NO, category 4

CSAR-02M120 Safety Relay Module Overview

The Pizzato CSAR-02M120 is a safety relay module from the CS AR series, designed for monitoring safety functions such as emergency stop circuits, guard doors, and interlocking devices in industrial machinery.

It belongs to the CS AR-02 family, which typically provides an expanded safety output configuration (commonly 3NO outputs), making it suitable for applications requiring multiple safety contactor control.

Main Function

• Monitoring of safety gate switches and interlocks
• Emergency stop (E-stop) circuit supervision
• Safe shutdown of industrial machines
• Control of multiple safety contactors via redundant outputs

Key Features

• Supply voltage: 120 Vac
• Safety outputs: 3 NO safety outputs (CS AR-02 family)
• Safety level: Category 4 / PL e / SIL 3
• Function: Dual-channel safety monitoring
• Mounting: DIN rail (22.5 mm compact housing)
• Connection: Plug-in screw terminals

Safety Performance

Designed for high-risk machinery, the CSAR-02M120 complies with:

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

This ensures redundant internal safety architecture and fail-safe operation in case of faults.

How It Works (Simple Explanation)

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

Typical Applications

• Machine guarding systems
• Industrial automation lines
• Robotics and conveyor systems
• Packaging machinery
• Production equipment safety circuits

Quick Summary

The CSAR-02M120 is a 120V AC safety relay module with expanded safety outputs, designed for Category 4 / PL e / SIL 3 applications where multiple safety contactors must be controlled reliably.
