Abstract
A remote control system comprises a central control station and at least one local station installed remotely from the central control station and connected thereto through a power transmission line. The local station has a plurality to devices connected in parallel to one another at the output. The power for actuating the devices is supplied from the central control station. For controlling actuation of the devices, binary control signals are serially sent from the central control station to the local station through the power transmission line in synchronism with clock pulses in a train including a start pulse. In the local station, the binary control signal are extracted in response to the start signal and converted into parallel control signals by utilizing the clock pulses to be applied to output circuits provided for controlling the devices.
