Allen-Bradley - MSRT - Minotaur Monitoring Safety Relay

The Allen-Bradley MSRT is a monitoring safety relay from the Minotaur series, designed to enhance machine safety by monitoring emergency stop devices and safety interlock switches. It is suitable for applications requiring single-channel input monitoring, providing reliable safety control in lower-risk environments. 

Key Features:

• Single-Channel Input: Monitors one normally closed (N.C.) safety input, ideal for gate interlocks and emergency stop buttons in lower-risk applications. 

• Automatic/Manual Reset: Offers flexibility with selectable automatic or manual reset functions, accommodating various safety requirements.

• Safety Outputs: Equipped with three normally open (N.O.) safety outputs for direct control of actuators or contactors.

• Auxiliary Output: Includes one normally closed (N.C.) auxiliary output for status indication, facilitating system monitoring.

• Compact Design: Features a slim . mm wide housing, allowing for efficient DIN rail mounting and space-saving installations.
