Complete control of your lighting system is finally within reach thanks to the Unison Echo® Relay Panel Feedthrough. It supports 120 and 277V power for on/off and 0-10V lighting control for up to 24 or 48 20A relays. The Echo Relay Panel Feedthrough is an ideal companion for retrofits in need of dimming and switching, or venues that need 120 and 277V plug loads and emergency circuits, all within the same panel. Standard Ethernet connection provides control via streaming ACN (sACN) and access to a Web UI for easy setup and configuration. Easy connectivity to Echo Occupancy and Light sensors and the Echo TimeClock makes this panel great as a stand-alone, room-based solution or as part of a fully integrated system.
