Allowable Input Resistance 240 ohms Description Reset Auto./Manual or Monitored Manual Outputs 2 N. O. Safety, 1 S.S. PNP Aux. The Allen-Bradley Guardmaster Minotaur MSR123RT is a safety monitoring relay that provides two normally open safety contacts and a solid state auxiliary output for use with interfacing to PLCs. Output Utilization per IEC 60947-4-1 (Resistive) AC-1: 8A/250V AC DC-1: 8A/24V DC ➊ Output Utilization per IEC 60947-5-1 (Inductive) A300, AC-15 6A/250V AC, 6A/125V AC N300, DC-13; 3A/24V DC; 6A/24V DC @ 6 ops/min Thermal Current (non switching) See limit curve Max 10A in one circuit Reset and output monitoring is determined by the wiring configuration. Automatic/manual reset can use a jumper or can be used to check operation of external contactors. Monitored manual requires the use of a manually operated normally open momentary switch. Output, Solid State 20mA @ 24V DC The MSR123RT has 2 normally open safety rated outputs. The safety outputs have independent and redundant internal contacts to help ensure the safety function. The solid state auxiliary output is a PNP circuit with short circuit protection designed to indicate the status of the MSR123RT. The MSR123RT can be connected to either a single or dual channel safety gate or e-stop, or can be connected to a light curtain that provides cross fault detection.
