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.

Features and Benefits:

• 2 N/O immediate safety rated outputs
• 3 N/O delayed safety outputs
• Can be connected in four different input wiring configurations: 1 N/C, 2N/C, or 2 PNP connections from a light curtain
• Cross fault monitoring
• Monitored or automatic reset
• Removable terminals
• Category 4 per EN 954-1
• Stop category 0 and 1
• Light curtain, E-Stop, Safety Gate inputs

What are Safety Relays?

Safety relays are devices which are used to monitor for errors or faults in a machine safety system, and can implement safety commands when they detect these errors to bring the risk down to an acceptable level. By doing this, they defend against hazards which could cause injury to personnel and damage to machinery. Single function relays manage one specific function, while multi-function relays can oversee different activities. Safety relays can also be connected to each other. They are often used in industrial environments such as factories, as part of a safety control circuit for dangerous machines. Typical applications include: safety mats, emergency stop push-buttons, light curtains, and magnetic switches. Rockwell Automation offer high-quality, reliable safety relays which give exceptional performance and ensure maximum protection and productivity.
