1. A modular power controller for selectively controlling the supply of electrical power to a plurality of separate electrical loads, comprising:

  • master digital microcontroller means, including master program means and memory means containing load command information for each of said electrical loads;

    serial data bus means;

    said master digital microcontroller means being located at a first location having a first serial output port connected to said serial data bus for selectively issuing load command information in digital serial form onto said serial data bus for each of said plurality of electrical loads;

    a plurality of load control means, said load control means being spaced from one another and positioned at other locations spaced from said master controller means;

    each said load control means being connected to said serial data bus for receiving said command information;

    each of said load control means comprising;

    slave microcomputer means, including slave program means;

    a plurality of electrical load circuits associated with said microcomputer means;

    said slave microcomputer means for receiving said load command information in serial form transmitted by said master digital microcontroller means via said serial bus and processing said received command information, and said slave microcomputer means selectively providing power to respective ones of said plurality of electrical load circuits based upon the processed load command information.
