Overview

The Echo Relay Panel Feedthrough is a control-oriented switching and power control built with today and tomorrow’s lighting loads in mind. Freely mix normal and emergency 120–347 V single-pole loads and either 120/208 V or 277/480 V double-pole loads in the same enclosure. With built-in station and sensor support via contact input, DMX and Ethernet connectivity, and optional 0–10 V dimming or DALI output, Echo Relay Panels easily integrate into a broad range of systems and applications.
