Abstract

PURPOSE:To make it possible to select an operation mode by only connecting the electric power source to the electric power source terminal, by connecting the output part of the photocoupler which has been connected to the electric power source terminal of each operation mode, between the detection circuit and the output circuit, and switching a signal transfer between both the circuits. CONSTITUTION:A nearby sensor circuit 1 has an output terminal 1c, and output parts 3S, 4S of the photocoupler are connected between two input terminals 2a, 2b of the output circuit 2. The input terminals 2a, 2b are used for normal-open and normal-close of the switching element of the output circuit 2, respectively. When the DC power source 81 is connected between the terminal C and the terminal A, and the load 7 is connected between the positive side of the electric power source 81 and the terminal D, since a current flows through the input part 3P of the photocoupler, its output part 3S becomes on, and the operation mode becomes normal- open. Also, when the electric power source 81 is connected to the terminal B, since the output of the terminal 1c is sent to the terminal 2b, it becomes a normal-close mode.
