  • Control/supervisory signal transmission system
    Patent number: 5223826
    Abstract: A bidirectional control/supervisory system for transmitting control signals from a controller to devices and transmitting supervisory signals from sensors monitoring the devices to the controller through a common transmission line. A transmission/reception control circuit generates a timing signal and a supply voltage of constant level, and converts the voltage into clock pulses having voltage levels differing from the supply voltage. The clock pulses are outputted to the common transmission line under the timing of the timing signals.
