Allen-Bradley 440R-G23110 Monitoring Safety Relay

Product Dimensions：

The Allen-Bradley 440R-G23110 (part of the GSR or Guardmaster Safety Relay family) is a high-performance GLT (Guardmaster Light Curtain) safety relay. It is designed to simplify safety system complexity while maintaining high reliability for industrial automation.

## Product Overview

The 440R-G23110 is a versatile safety relay specifically optimized for applications involving light curtains, emergency stops, or safety gates. It features a compact 22.5mm housing and utilizes the Single Wire Safety (SWS) connection, which allows for seamless expansion without consuming additional outputs.

## Technical Specifications

## Key Advantages

• Space Efficient: The slim profile saves valuable DIN rail space in control cabinets.

• Logic Flexibility: Features a rotary switch on the front panel that allows you to select between different functions (e.g., Monitored Manual Reset vs. Automatic Reset).

• Easy Expansion: Supports the Single Wire Safety (SWS) link, allowing it to signal other safety relays in a chain with just one wire.

• Diagnostic LEDs: Clear indicators on the front face facilitate rapid troubleshooting by showing power, input, and output status.

## Precautions & Maintenance

• Wiring Integrity: Ensure that the input circuits are wired correctly for dual-channel performance to maintain the PLe/SIL3 safety rating.

• Load Protection: Always use external fuses for the output contacts to prevent welding in the event of an overcurrent.

• Environmental Limits: Operates best between -5°C and +55°C. Excessive vibration or moisture can reduce the lifespan of the internal electromechanical relays.

• Configuration Check: Always cycle power after changing the rotary switch settings for the changes to take effect.

## Product Applications

The 440R-G23110 is most commonly found in “Point of Operation” guarding, including:

1. Light Curtain Integration: Direct monitoring of safety light screens on assembly lines.

2. Emergency Stop Circuits: Handling E-stop strings for small to medium-sized machinery.

3. Safety Gate Monitoring: Working with interlock switches to ensure power is removed when a guard is opened.

4. Packaging Machinery: Managing high-speed stop requirements safely.
