Photocell Relays
A photocell relay is a twilight switch that measures the ambient light level and switches lighting on when it gets dark and off when it gets light. It is used in street, garden, residential complex, parking lot, sign and facade lighting so that lamps switch on and off automatically depending on daylight. The category includes the Entes FG-4 series, Tense and ABB photocell relays; there are types with adjustable light threshold, fuse protection, DIN rail housing, external sensor, and IP65 degree of protection stated in the product data. The ABB products also include a model that combines the twilight switch with a weekly program and an astronomical function. Choose the photocell relay according to the lux setting range, the output contact current and lamp type, whether the sensor is internal or external, the IP class suited to the mounting location, and the supply voltage. The contact values in the product names, such as 5 A and 7 A, are for ohmic loads; for lamps with LED drivers and ballasts, using a contactor is recommended. A photocell relay works according to ambient light; it is not a motion-detecting sensor or the safety photocell used on automatic doors.
