Abstract
Power controllers comprising solid state elements responsive to control signals of low power from a remote control location selectively close and open relatively high power circuits to load devices, and including logic circuitry for opening selectively closed power circuits upon occurrence of overloads therein. The controllers also act upon their failure to respond to commands to open or close the power circuit by blowing a protective fuse in the former case and signaling in the latter. The controllers may employ power darlington switches for closing and opening the power circuits. All or most of the logic circuitry may function in providing the control and the overload or mode failure response for two or more load devices.
