Product Description
ETC Unison Echo Relay Panel - Echo Relay Panel Feedthrough 48-way panel with 48 – 20A 208V double-pole relays
IMPORTANT NOTE: Panel pricing does not include system commissioning services. However, system commissioning services by a factory-authorized ETC service agency must be added onto the purchase of an ETC Echo panel. We can provide you with a quote for the system commissioning services. We will need the project name and address and full Bill of Materials to provide you with the estimate for system commissioning.
Model #ERP48-FT482P
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 0-10V control to our trusted conventional switching system. With built-in station, sensor, DMX and TimeClock controls and Ethernet connectivity, plus optional 0-10V dimming, DALI output and contact inputs, the Echo Relay Panel Feedthrough integration opportunities are limitless.
APPLICATIONS • Houses of worship • Ballrooms and convention centers • Multi-purpose rooms • Arenas and stadiums • Entertainment facilities with DMX control • Retrofits for lighting systems with existing breaker panels
