Input Simultaneity Infinite Maximum Input Resistance 160 ohms Description Outputs 6 N.O. Safety 1 N.C. Auxiliary 1 N.C. Monitoring The MSR122E is designed to be an expansion relay for use with the Minotaur safety relays. The MSR122E is typically used in safety system applications where additional outputs switching connections are needed to help shut down a manufacturing process, properly and safely. Output Utilization per IEC 60947-4-1 (Resistive) AC-1: 10A/250V AC DC-1: 10A/24V DC ➊Output Utilization per IEC 60947-5-1 N.O. (Inductive) N.C. The MSR122E can be connected as a single channel (1 N.C.) or dual channel (2 N.C.) input configuration. N.O. N.C.

One additional normally closed output is available to allow the host relay to monitor the status of the MSR122E. The safety, auxiliary and monitoring outputs have independent and redundant internal contacts to help ensure the safety function.
