GENERAL INFORMATION
The Echo Relay Panel Feedthrough is a control-oriented switching
and power control built with today and tomorrow’s lighting loads in
mind. Echo Relay Panel adds ETC’s latest Echo Control package with
support for 0–10 V control to our trusted conventional switching
system. With built-in station, sensor, DMX and TimeClock controls
and Ethernet connectivity, plus optional 0–10 V dimming, DALI
output and contact inputs, the Echo Relay Panel Feedthrough
integration opportunities are limitless.
