Honeywell 900C70-0460 I/O Modules
1.The Redundant Switch Module resides in a ControlEdge HC900 Redundant controller rack and interfaces with both CPUs of a redundant system and indicates which CPU is functioning as the Lead controller and which is the Reserve.
2.A key switch on the module sets the mode of both the Lead and Reserve controllers, guaranteeing
synchronization of CPUs.
3.A momentary contact position of the key switch allows the user to switch the Lead control function from CPU-A to CPU-B or vice versa.
4.The RSM module supports insertion and removal under power.
