Temperature /Humidity Transmitter TRH-303 4~20mA Output Application diagram and Instruction:   

Temperature/Humidity circuit set-up Diagram

TRH-303, 4~20mA temp/humidity transmitter

Application Note:

1. One (+) power wire to Humidity or Temp (+) terminal ; Both Temp/Humidity

2. The signal would be out from the (-) terminal and connect this wire to the (+) terminal of the controller AND

3. The (-) terminal is the connected to the Ground (-) of the power source.

Our transmitter is a two wire system with the positive (+) as power source and the negative is the Communication Source.
