The Wattstopper LC8-120/277 panel provides zone-based control of up to eight channels, or zones, of interior and exterior lighting. Zones respond to control signals from the internal system clock, or an accessory photocell, to automatically turn lighting on and off. The LC8-120/277 panel uses interchangeable relay modules, available separately, that can be selected to suit project needs. Relay options include the LCSP-2 dual single-pole module and LCDP-1 double-pole module.
