Abstract
Apparatus and associated methods related to providing safe electrical control and/or communication between a remote controller located in a safe location and interface system for a machine located in a hazardous location. The control and/or communication is provided via industrial-voltage power lines that traverse a barrier separating the safe location from the hazardous location. Control and/or communication is provided by reactively coupling to industrial power lines, which traverse the barrier, so as to superimpose a control and/or communication signal upon AC operating power provided to the machine. Each of the interface system located at the hazardous location and the remote control module located at a safe location provides such reactive coupling to the industrial-voltage power lines so as to communicate therebetween.
