Guardmaster Safety Relay 2NO output 24VDC

The Allen-Bradley Guardmaster Minotaur MSR125H/HP is a logic unit for monitoring and interfacing two-hand control devices with a safety-related circuit. It is for use with mechanical switches and the Rockwell Automation Bulletin 800Z Zero-Force touch buttons. It has two normally open safety outputs. The safety outputs have independent and redundant internal contacts to support the safety function. It requires the two switches to be operated within 0.5 seconds of each other and will only authorize the ON state while both switches are held down. If one of the switches is released, the output goes to the OFF state and the machine cannot be restarted until both buttons are released and then operated simultaneously. It conforms to EN 574 Category IIIC, which gives specific requirements for two-hand control units and logic devices. It has fixed terminals and the MSR125HP has removable terminals.
