Supplying current to and controlling several loads via 2-wire cable involves using decoders, connecting cable to low voltage source via power stage, detecting load on/off switch settings

摘要

The method involves connecting the loads to the cable in parallel via decoders and connecting the cable to a low voltage direct current source via a power stage connected to control electronics that detects the switch settings off on/off switches associated with each load. Individual load control is achieved by connecting each load to a different decoder counter output via a controllable power switch. An Independent claim is included for an arrangement for implementing the above method.
