The 440R-S845AER-NNL

The 440R-S845AER-NNL is a Guardmaster MSR57P Speed Monitoring Safety Relay from Allen-Bradley, a Rockwell Automation company. This safety relay is designed for motion applications that require interaction by personnel during operation. It is used for standstill detection on single and three phase motors without the need for sensors.

Technical Specifications

  • Input Current: 11 mA per input, maximum. The aggregate current of MSR57P, maximum, is 10.4 A at terminal A1, 13 MP outputs, 14, 24, SLS outputs 68, 78.
  • Short-circuit Protection: The relay is short-circuit protected at 2 A for 24V DC and 50 mA for 24V DC for the SLS_status output Y35 and Fault_status output Y37.
  • Output Current: The output Y1 is short-circuit protected at 20 mA for 24V DC.
