The twilight sensor is required to record and evaluate brightness. Brightness is recorded via a photoelectric diode and electronically converted into an analogue output signal of 0 V – 10 V.
For external installation and connection to the weather station REG-K/4-gang or the analogue input REG-K/4-gang. These two devices provide the supply voltage necessary to operate the sensor.
Measuring range: 0 to 255 lux, linear
Output: 0 … 10 V short-circuit-proof
External power supply:
Voltage: 24 V DC (15-30 V DC)
Power consumption: approx. 5 mA
Incoming cable: using PG7 screw fitting
Recommended cable: 3 x 0.25 mm2
Type of protection: IP 65
Dimensions: 58 x 35 x 64 (W x H xD)
In KNX, to be completed with: Weather station REG-K/4-gang MTN682991, Analogue input REG-K 4-gang MTN682191.
