    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.
