Light Sensor Controllers
The PC and LM series are one or two channel electronic lighting controls. They are provided with a waterproof light level sensor that can be remotely mounted up to 330 feet away. For large installations, up to 10 units (20 channels) can be connected to a single sensor. The integral light sensitivity adjustment provides a wide range of settings, making these units applicable for control of indoor and outdoor lighting as well as automatic awnings or shades. The PC1 and PC2 operate strictly via a light level adjustment. The PC2 unit has an independent light level setting for each channel. Either unit can be connected in series with any Grasslin Time Switch to provide time-of-day control.
