IIIC per EN 574 Approvals C-Tick, CE marked for all applicable directives, cULus & BG Power Supply 24V DC, 115V AC or 230V AC Power Consumption 2W Safety Inputs 1 N.C. and 1 N.O. Input Simultaneity <0.5s Maximum Input Resistance 40 ohms Description Reset Automatic Outputs 2 N.O. Safety 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. Output Utilization per IEC 60947-4-1 (Resistive) AC-1: 6A/250V AC DC-1: 6A/24V DC ➊ Output Utilization per IEC 60947-5-1 (Inductive) B300, AC-15 6A/250V AC, 6A/125V AC P300, DC-13; 3A/24V DC 6A/24V DC @ 6 ops/min The MSR125H/HP has 2 N.O. safety outputs. The safety outputs have independent and redundant internal contacts to help ensure the safety function. Thermal Current (non switching) 1x6A, 2 x 4A Fuses Output (external) 6A slow blow or 10A quick blow Min. Switched Current/Voltage 10mA/10V Power On Delay 1s 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.
