摘要: An input module used in a factory automation apparatus, which is constituted by a bidirectional conduction circuit for connecting to an AC power source or DC power source with both plus or minus common line, a constant current circuit for supplying constant current, and a load circuit accepting the constant current. When the voltage range is less wide, a bidirectional conduction circuit and a filter circuit are used.

摘要: An output module which is used in a factory automation control apparatus is disclosed. The output module is connectable to both of AC and DC power sources, which is constituted by a control element controlled by the output signal in the factory automation control apparatus, and a drive element being bi-directionally conducted by the signal of the factory automation control apparatus. A first embodiment uses a full wave rectifier to rectify the current from/to the load, and a second embodiment uses two opposite channel type transistors to respectively conduct during different polarities.
