Allen Bradley 440R / MSR138.1DP Safety Monitoring Safety Relay, 24V ac/dc, Single Channel, 2 Safety Contacts

Rockwell Automation MSR138DP Dual Channel Safety Relay with Immediate and Delayed Outputs

Ensure dependable monitoring and fault detection for your control safety system with the Minotaur MSR138DP Dual Channel Safety Relays with Immediate and Delayed Outputs, by Rockwell Automation. These safety devices help prevent risk of damage to machinery and protect personnel from injury, minimising downtime and giving you peace-of-mind.

The MSR138DP is a versatile safety relay which can be connected in four different input wiring configurations to suit your application: 1 N.C., 2 N.C., or 2 PNP connections from a light curtain. This unit checks for cross faults across the two inputs when connected in the 2NC fashion, and when connected to light curtains, the light curtain must perform the cross fault detection. This relay has output monitoring that can be configured to either automatic/manual reset or monitored manual reset. With manual reset, the safety relay checks the output monitoring circuit through the manual application of the reset switch. The safety outputs have independent and redundant internal contacts to help ensure the safety function.
