Honeywell ControlEdge HC900 Redundant Switching Function

The 900RSM-0200 module manages redundant controller rack selection within the ControlEdge HC900 architecture. It uses a keyed mechanical switch assembly to define controller operating states and provides visual status indication through green arrow LEDs.

In addition, the module operates from a 5 V supply rail and maintains a maximum loading requirement of 22 mA. The switch mechanism provides three fixed positions and one momentary position for manual redundancy control operations.

The module supports Honeywell process control hardware configurations where redundant controller racks require local physical selection and status monitoring.
