ABSTRACT:
A power controller system for providing electrical power to a multiplicity of loads at outputs thereof under direction of a plurality of input controllers operating a corresponding plurality of output energization means with the controllers capable of having different output states in response to differnt system input signals, the controller having selected common components for forcing selected ones of said input controllers to terminate power to corresponding loads. Current sensing means upsetting current balances in bipolar transistors are used to sense beyond-limit currents.
