Abstract

PURPOSE:To enable to select the operating mode simply, by making normal open operation with a photocoupler when one of two sets of power supply terminals receives power supply, and making normal closed operation with the photocoupler when power supply is applied to another. CONSTITUTION:When a power supply is applied to a power supply terminal 101, a photocoupler input section 41 and a light emitting diode 71 illuminate, an output section 31 of the photocoupler turns on, and an output circuit 5 makes normal open operation. When a power supply is applied to a power supply terminal 102, an input section 42 of the photocoupler and a light emitting diode 72 illuminate, the output section 32 of the coupler turns on and an output circuit 5 makes normal closed operation. Since illuminated color of the light emitting diodes 71, 72 is different, the display of operation mode can be made.
