Abstract

PURPOSE: To make it possible to control a two-way flow of current by connecting a contactless switching element such as a contactless transistor between a signal output terminal and common output terminal via a diode bridge circuit.
CONSTITUTION: Signal output circuit 30 of external equipment 1 is provided with several signal output terminals D01...D0n and one common terminal COMO. Then, several ON-OFF signals outputted from arithmetic control part 10 are latched 31 and those ON-OFF output signals allow LEDINV1...INVn to come ON-OFF via inverters INV1...INVn. Further, LEDs P1...Pn emit light to supply a signal to a diode bridge circuit by way of photo detecting elements TrPTR1...TrPTRn. Consequently, a contactless switching element is connected between a signal output terminal and common output terminal via the diode bridge circuit to exercise control over a two-way flow of current.
