Abstract

PURPOSE: To vary the input impedance of the circuit and to cope with the voltage of a different operation power supply by forming a signal input circuit through series connection of a photocoupler and plural impedance elements and providing a common input terminal and an input terminal connecting to each impedance element.
CONSTITUTION: A signal input circuit 10 is constituted by connecting a photocoupler 11, a 1st impedance element 12a and a 2nd impedance element 12b in series. Moreover, a common input terminal 5a connecting to a photocoupler 11, a low voltage signal input terminal 5b connecting to the connecting point between the 1st and 2nd impedance elements 12a, 12b and a high voltage signal input terminal 5c connecting to the 2nd impedance element 12c are provided. Then the combination among the common input terminal 5a and the other input terminals 5b, 5c is selected properly. Thus, the same solid-state contactor is applied to the specification of the voltage and input impedance of the different operating power supply.
