Minotaur MSR125H/HP
Description
The Allen-Bradley Guardmaster Minotaur MSR125H/HP is a logic
unit for monitoring and interfacing two hand control devices with a
safety related circuit. The MSR125H/HP is for use with mechanical
switches and the Allen-Bradley Bulletin 800Z Zero-Force Touch
Buttons.
The MSR125H/HP has 2 N.O. safety outputs. The safety outputs
have independent and redundant internal contacts to help ensure the
safety function.
The MSR125H/HP 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.
The MSR125H/HP conforms to EN574 Category IIIC, which gives
specific requirements for two hand control units and logic devices.
The MSR125H has fixed terminals and the MSR125HP has
removable terminals.
