Allen Bradley 440R / MSR131RTP Safety Monitoring Safety Relay, 115V ac, Dual-Channel, 3 Safety Contacts

Enhance your safety control system and establish dependable monitoring and fault detection with the Minotaur MSR131RTP Safety Relay(s) by Rockwell Automation.

This versatile safety relay can be connected in four different input wiring configurations to suit your application requirements: one normally closed, 2 normally closed, 2 PNP connections from a light curtain, or a four-wire safety mat. The MSR131RTP relay checks for cross faults across the two inputs when connected in the 2NC fashion. The light curtain must perform the cross fault detection when the safety relay is connected to light curtains. It can accommodate either automatic/manual reset or a monitored manual reset. This unit features three normally open safety rated outputs, two normally closed auxiliary outputs, and two solid-state outputs.

The Minotaur Safety Relay is the ideal solution for relatively small safety applications and helps protect personnel and machinery, minimising downtime and ensuring greater efficiency.

• Monitored or automatic reset
• Stop category 0
• Removable terminals
• Reliable cross fault monitoring
• Compatible with light curtains, safety mats, and E-stop inputs
• Safety outputs have independent and redundant internal contacts to help ensure the safety function
• Non-safety auxiliary output provides an external signal to indicate the status of the safety outputs
• Cat. 4 per EN954-1

Install this safety relay from Rockwell Automation to stop faults disrupting your electrical system. When an issue emerges, it closes its outputs to deactivate the relevant appliance and let operators carry out an inspection safely. The unit features easy-to-read LED lights that indicate when the relay is in operation and also draw attention to a fault, keeping you informed on the status of your circuit. A single-function setup lets you programme the relay to focus on the issues most critical to your application.

• Features both automatic and manual reset modes, letting you select the functionality that best suits your needs
• Dual-channel design checks two inputs for faults at once to monitor more areas of your safety application
• Designed to mount on a 35mm DIN rail to protect your rail-mounted components
• Quick 15ms switching time, giving you confidence that the relay closes electrical connections before critical faults cause damage or harm

• CE (Conformitè Europëenne)
• UL (Underwriters' Laboratories)
• EN 954-1 (European Norm)

Yes, this relay is compatible with light curtain sensors. This means you can use the device to protect operators and appliances around moving machinery.
