Abstract

PURPOSE: To lower a fault ratio while improving reliability by providing an output feedback line and also by performing output control from an output line to the output feedback line via a contactless circuit.
CONSTITUTION: Light emitting diode 10 indicates that an input arrives from input part 17 and light emitting diode 11 also indicates the outputting of output part 26 by feeding back to output feedback line 61, so that interlock setting between the input and output can easily be known. In addition, the input control from input part 17 to input lines 41 and 42 and the output control from the output line to output feedback lines 61 and 62 are performed using transistors 14, 15, 12 and 13, contactless switches. Consequently, the fault ratio lowers and the lifetime can be prolonged, improving reliability.
