Working Voltage 15-36 (V)
Humidity accuracy: +-3% RH
Humidity measurement range: 0-99.9% RH
Current output: 4-20 m A

Instructions:
1. Power cord positive DC18~36V (red wire)
2. Power ground wire GND (black wire)
3. Humidity current output 4~20MA (yellow line)
4. Temperature current output 4~20MA (white line)
 
Installation sequence:
1. Connect the red, black, yellow and white four wires of the 4-core cable transmitter end to the 1, 2, 3 and 4 feet of the transmitter connector respectively (the shielding layer with shielding wire is connected to the power supply ground);
2. The other end is connected to the power supply and the voltage detection equipment or other corresponding equipment.
3. After checking the correct connection, the power supply can be connected to check whether the output of the transmitter is normal.
4. Now the transmitter can work properly.
 
Description:
AF1020 pipeline current-type temperature and humidity transmitter uses capacitive digital temperature and humidity sensor as humidity measurement component, with stable and reliable signal processing circuit, converts the temperature and humidity in the environment into corresponding standard signals, and selects high-quality integrated digital temperature and humidity sensor, which ensures the excellent performance of the transmitter. Long-term stability, low delay, and strong resistance to chemical pollution, the transmitter has excellent repeatability.
