Rockwell Automation Minotaur MSR126R and MSR126T, Single or Dual Channel Safety Relays


Experience dependable basic fault detection for your control safety system with the Minotaur MSR126R and MSR126T Safety Relays by Rockwell Automation. These 22.5mm relay devices have 2NO (Normally Open) Safety Rated Outputs, which have independent and redundant internal contacts to help ensure the safety command. With these Safety Relays you can prevent risk of damage to machinery and protect personnel from injury, minimising downtime and giving you peace-of-mind.

MSR126R/T: This relay is designed specifically for connection to a single channel safety gate, a single channel e-stop or a light curtain that provides cross fault detection.

MSR126.1R/T: This relay is intended for connection to a dual channel safety gate or e-stop, as it performs cross fault detection across the inputs.

MSR126R and MSR126.1R: These safety relays are made for applications where a monitored manual reset is necessary. Monitored manual reset requires the use of a manually operated normally open momentary switch to activate the outputs.

MSR126T and MSR126.1T: These units are intended for use in applications which demand automatic/manual resets. This type of reset allows a jumper across the S33-S34 circuit, and so does not perform output monitoring.

Features and Benefits:


• Stop category 0
• Cross fault monitoring
• Monitored manual or automatic reset
• Cat. 4 per EN954-1
• 2 Safety contacts N.O.
• Single/dual channel operation
