ACI (Automation Components), A/LLS-T(0-500)-4X, 126748, Light Level Sensor with Transmitter, 0 to 500 f.c., 4X Enclosure

The A/LLS-T light level sensors and transmitters are used for applications such as turning on or off indoor or outdoor lighting. The sensor can be mounted in a NEMA 3R rated enclosure. In darkness, the sensor has a resistance in excess of 1M ohms, versus a resistance of less than 1.5K ohms in bright light. The A/LLS-T incorporates a transmitter with the sensor to produce a non-linear 4-20 mA output signal. The A/LLS-T is calibrated for 4 mA in darkness and 20 mA in bright Light. Typically the 0-500 is used for outdoor parking lot lighting/signage applications and the 0-100 is used for indoor lighting.

Applications:

Indoor/Outdoor Lighting Control Systems & Building Automation Systems
