The Verasys lighting controller (VAC1001) is a Verasys application controller that controls up to nine lighting contactors that are grouped in zones. You can control and schedule up to eight zones from a light level sensor. You can connect either a binary or analog light level sensor and drive the zone control based on light level. The zone also includes an associated schedule that can drive the output of the zone.
You can drive contactors for outside lights because of the flexibility of the controller; lights come on when it is dark and turn off at a fixed time or drive other zones based on the schedule. The first seven zones have a binary input that can override the zone output. You can set the binary input to momentary and allow a set amount of time for the override, or maintain the input for a more permanent override.
For more information, refer to the Verasys Lighting Controller Application Note (LIT-12012524).
