ABSTRACT:
An interface driver circuit, for use in a programmable energy load controller system, comprises a pair of optically-coupled input sections, respectively receiving data and a special signal of digital nature and a first voltage polarity. A buffer amplifier section is coupled to the data input circuit for driving a twisted-wire transmission line, coupled to the paralleled inputs of a plurality of receivers, with logic signals alternating essentially between ground potential and the first voltage at the first polarity; a second amplifier section is enabled by the special signal input section and impresses a voltage of the remaining polarity across the interface driver circuit output when commanded at the special signal input, regardless of the state of the data signal at the first input.
