The ETC ERP-12R1-12B1-ML3P is a Unison Echo Relay Panel designed for control-focused lighting power distribution in permanent installations. Built as a main feed relay panel, it supports 24 relay positions and a 30-position breaker subpanel, making it suitable for venues that need centralized branch control with flexible circuit layouts. Support for 1-, 2-, and 3-pole relays and compatibility with 300 W phase-adaptive or forward-phase dimmers allows the panel to serve a wide range of load types in theaters, schools, houses of worship, conference centers, retail spaces, and restaurant environments.

For system integration, the panel supports Echo, DMX-512, streaming ACN, Astronomical TimeClock, and stand-alone operation. An onboard Ethernet port enables web-based configuration and management, while the local interface provides direct access to setup, playback programming, and individual channel control. Built-in EchoConnect power supports multiple Echo control and output devices, and measured energy usage reporting per branch circuit gives facilities added visibility into connected loads.

The enclosure is sized for standard stud-width construction with a 14" width and 4" depth for flush or surface mounting. Separate Class 1 and Class 2 wiring areas, removable access covers, manual override per circuit, and optional control card support for 0–10 V, contact input, and DALI help the panel fit cleanly into modern architectural lighting control systems.
