Rockwell Allen‑Bradley 440R Series Safety Relay Full Application Overview

1. Posicionamento do produto

The 440R series is the core safety relay lineup of AB Guardmaster, including traditional MSR basic type, EM expansion type, GSR intelligent communication type, time-delay and two-hand dedicated types. All meet PL e / Cat.4 / SIL 3 high safety levels.

Montagem em trilho DIN, compatible with emergency stop, porta de segurança, light curtain, safety mat, two-hand button and all standard safety sensors.

2. General Safety Application Scenarios

2.1 Emergency Stop Circuit Monitoring

Dual-channel contact detection for mushroom emergency stop buttons

Immediate power cut on E-stop; restart allowed only after reset

Standard safety circuit for all industrial machines

Typical model: 440R‑H23180(MSR230P), 440R‑M23088

2.2 Safety Guarding Door / Access Door Interlock

Machine guard doors, cabinet doors, perimeter fence doors stop machine when opened

Machine prohibited from starting if door not fully closed and locked

Compatible with hinge safety switches, bolt safety switches, electromagnetic door interlocks

2.3 Cortina de luz de segurança / Safety Scanner Interlock

Interface with photoelectric light curtains and laser safety scanners

Automatically cuts power when personnel enter hazardous area; reset permitted after evacuation

Ideal for robotic stations, stamping and pick-and-place stations

2.4 Two-Hand Synchronous Start Control

Safe two-hand start for presses, punch presses and riveting machines

Machine action only activates when both buttons pressed simultaneously to prevent hand injury

Dedicated models: 440R‑D23166, MSR125H

2.5 Time-Delay Safe Stop

Delayed power-off for fans, inertial loads and high-speed spindles

Safety signal triggers delayed output disconnection; unlock maintenance only after full mechanical stop
