ETC Unison Echo Relay Panel - 48 Single Pole Feedthrough Panel with 48 Relay
Model #ERP48-FT48
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.
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
FEATURES • 120V-277V single-pole and 208 or 480V double-pole switching • Up to 48 relays per panel • Switches all relays at once or with configurable delay • Mechanically latching relays fully rated to 20A • Manual ON/OFF override with position indication • Relays support field installation and replacement • Echo, sACN, DMX-512, TimeClock, or stand-alone control • Built-in EchoConnect® power supply for up to 6 Echo stations/ sensors and 5 output products • Built-in network interface provides: - Advanced control of relays over streaming ACN (sACN) - Web UI for configuration • Local control with Astronomical timeclock and manual override per circuit • UL924 LISTED emergency control bypass contact input - Voltage barrier for normal/emergency mixed use panels • UL and cUL LISTED
