The input signals are considered good according to the following criteria: Signal Level As specified in 5601MSC manualĬhangeover is a voting system based on which source has the most good signals and that the good signals on the current master are also present on the backup master. Outputs 2 GPI outputs connected from Master A through AUXI/O AĢ GPI outputs connected from Master B through AUXI/O BĬonnector 6 pins on 12-pin removable terminal block Inputs 2 GPI inputs connected to both Master A and Master B 10kW internal pull-up to +5V when relay is in active positionĬonnector 4 pins plus 2 ground pins on 12-pin removable terminal block Inputs Opto-isolated input with internal pull-up to +5V High Master A and B have equivalent signals Low Master A & Master B differ or PSU failure GPI1 Master select in Manual GPI control mode Number 16 groups each consisting of two inputs and one output
