PLC

Programmable Logic Controller is used to program operating times to turn unit(s) on or off. Set weekday and weekend times. Automatically adjusts for daylight savings time. This controller can be mounted inside a sign or controller for single use, or remotely to operate multiple signs or signals.This unit is also successfully used in conjunction with a photo sensor relay. These two units combined can create a multitude of uses such as vehicle awareness. An approaching vehicle trips the photo sensor and triggers an illuminated sign and the PLC will keep the sign illuminated for a predetermined amount of time.
