Overview

The Unison Echo Relay Panel is a control-oriented power center built with today and tomorrow’s lighting loads in mind. It supports up to 24 relays with integral branch breakers, power-usage reporting and sophisticated control inputs. 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.
