Applications / Use Case
The Allen Bradley 440R-GL2S2T safety relay is ideal for industrial environments requiring a reliable safety monitoring device for guard locking and emergency stop circuits. It ensures machines only operate when safety guards are properly secured and locked, preventing accidental start-up during maintenance or while the guard is open. Typical applications include automated production lines, robotic cells, packaging machinery, and press safety circuits. This relay’s time-delay function allows safe release sequences and provides flexibility in safety control system design. It is commonly used alongside safety sensors such as proximity switches, magnetic switches, and emergency stop buttons, fitting seamlessly into safety control architectures governed by strict industry standards.Related Resources
