The ETC EDRC-G2 is a relay controller designed for architectural and installed AV environments that need dependable switching of lighting loads through the EchoConnect control network. It supports 120–277 VAC power input and uses a normally open 20 A fully rated relay, making it suitable for managing general purpose, tungsten, fluorescent, and LED loads in a wide range of commercial spaces.

For integrators and facility teams, the EDRC-G2 is built to simplify deployment. Plug-and-play operation allows the controller to be put into service without external programming software, while support for Unison Echo control stations and responsive controls helps it fit into broader ETC Echo systems. EchoConnect’s two-wire, topology-free approach gives more flexibility in routing control wiring, whether the project uses bus runs, home runs, or mixed layouts.

This controller is well suited for houses of worship, education, hospitality, healthcare, offices, conference rooms, meeting rooms, and retail installations where fixture-level or zone power switching is required. Its mechanical design includes onboard configuration controls, LED indication per zone, conduit knockout mounting, and field software upgrade capability via microSD, giving installers practical tools for commissioning and ongoing support.
