ABSTRACT:
A switchover device switches over a double module between first and second modules manually or automatically, in which the control signals and switchover signals are generated with of the logic combination circuits and relays, to simplify signal processing of the system. The device for switching over the double module with first and second modules, includes a key input circuit including a mode setting key and a module selecting key, a manual switchover circuit for selectively generating a first control signal for switching over to the first module and a second control signal for switching over to the second module in response to input of the module selecting key, an automatic switchover circuit for selectively generating the first and second control signals according to first and second status signals generated from the first and second modules, a switchover mode selecting circuit for selectively outputting signal outputs of the manual switchover circuit and the automatic switchover circuit in response to input of the mode setting key, and a control selecting circuit for forming a communication path to the first or second module in response to the first and second control signals from the switchover mode selecting circuit.
