Abstract

PURPOSE:To execute the control without being influenced by an electric disturbance, by constituting a device of an electric signal/optical signal converting circuit, an optical signal/electric signal converting circuit, a remote control device and a multicore optical cable. CONSTITUTION:A main controlling circuit 2 reads a state of switches 3A-3C of a remote control device 3 as an electric signal from a multicore cable 4A through an optical fiber 6A and an optical signal/electric signal converting circuit 5A, and leads a unit to a prescribed operation. Also, it reads a signal of a sensor 8, compares it with a value set by the switches 3A-3C, and controls a load 7 so that it is opened and closed. Also, said signal is transferred to an electric signal/optical signal converting circuit 5C by a multicore cable 4C, and an optical signal converted in this circuit makes prescribed indicators 3D-3G emit light and display through an optical fiber 6C. In this way, each circuit is coupled with a multicore fiber cable only, and a signal transfer is executed by an optical signal, therefore, no radio wave wave disturbance is feared, and there is not influence by an external noise.
