Allen-Bradley MSR126.1R Guardmaster Safety Relay Module

Allen-Bradley Guardmaster MSR126.1R is a two-channel, monitored safety relay module in the Guardmaster Minotaur line designed for safety circuits on industrial machinery. It accepts a 24V AC/DC supply and provides two normally open safety contacts, wired through fixed screw terminals in a 22.5 mm-wide housing. As a Monitored Manual Reset device, it requires a deliberate reset after a fault before re-energizing the outputs. The safety outputs are rated to switch up to 6 A at 250 V AC (AC-15) with DC ratings of 3 A at 24 V DC for DC loads, making it suitable for safety interlocks, door switches, and emergency-stop circuit implementations in automation systems.
