AUTOMATIC CHANGEOVER OPERATION (5601ACO2)
For critical infrastructure requirements a 5601ACO2 can be used to connect two 5601MSC units in a
dual redundant configuration. The 5601ACO2 monitors signal health to decide which of the 5601MSC
units will be connected to the downstream outputs. See the connection diagram below.
