ACI A/LLS-T(0-500) : Light Level Sensor w/ Transmitter, 0-500 foot-candles (fc), 4-20 mA (3 Wire) Output, NEMA 3R Enclosure
TheA/LLS-T light level transmitter is used for applications such as turning on or off indoor or outdoor lighting based upon the amount of available light. The sensor can be mounted in a NEMA 3R rated enclosure. 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
