The LC8 Single Zone, Daylight Harvesting Photo Controller automatically switches a dry contact in response to changes in natural light. This 24 volt control module can be used as a stand-alone basic controller for daylighting sensors or interface with standard options such as time clocks, dimmers, contactors or occupancy sensors. With adjustable ON/OFF setpoints at the control unit, it is a convenient, flexile low maintenance lighting control solution. An input time delay prevents switching due to temporary light conditions. It has a fail-safe feature so that lights turn on if the sensor is disconnected, damaged or the wire is broken. It can be used with PLC Multipoint CES or MAS daylighting sensors, MK7-B sensors and many other lighting control photosensors. Temperature range is -12.2° to 140°F (-11° to 60°C). It is an ideal solution to meet California Title 24 daylight harvesting needs. The dual setpoint LC8 precisely switches loads according to the selected light level configuration. LOW and HIGH light levels are calibrated to their setpoints at the control board. As the sensor detects a diminishing light level that corresponds with the LOW setpoint, the control board matches the two signals and the lights are switched ON. As the sensor detects an increased light level, the control board's HIGH setpoint switches the lights OFF. The LOW and HIGH setpoints are separated by a "deadband" which prevents the sensor from switching light levels between the setpoints, thus eliminating nuisance or intermittent changes. RoHS Compliant. PLC Multipoint has been the leading manufacturer of daylighting sensors for over 25 years. Headquartered in Everett, Washington, all PLC Multipoint products are manufactured in the USA.
