PURPOSE:To facilitate wiring construction by reducing the weight of wiring by decreasing the number of wires, by connecting a sequence controller and terminal equipment through optical fibers. CONSTITUTION:An oscillator of a channel 6 having received a 5V signal inputted to a control terminal C6 sends a frequency signal of the channel 6 to an output terminal 06, and it is supplied to a synthesizer 14 for OR synthesis together with other signals. Its composite signal is sent to sensor units 18-25 through an electrooptical signal converting means 16, a branching device D9, and optical fiber cables l3 and l10, and a frequency signal which corresponds to the channel 6 operates the sensor unit 23 through a photoelectric signal converting means 37 to turn on an LED6, and also to supply a 100V AC voltage to a terminal equipment terminal S6. The 100V signal inputted to a terminal equipment terminal S3 is converted into a 5V signal by a voltage-level converting means 35, and the signal is modulated by the signal of an oscillation part 36 to be inputted to a means 17 through the means 37 and a branching device 37; and a prescribed frequency is obtained by a split filter 15 to turn on an LED3 and is inputted to a terminal C3. |
