Lutron TR-RH2W is a 2-wire humidity transmitter.
- It measures humidity from 10%RH to 95%RH.
- Output is 4 to 20 mA DC.
- Specific mA values correspond to different humidity levels: 5.6 mA for 10%RH, 12 mA for 50%RH, 16 mA for 75%RH, and 19 mA for 95%RH.
- Uses precision capacitance type humidity sensor.
- Allows for external zero and span adjustment.
- Can handle high cable load resistance, allowing installation far from the controller/indicator.
- Offers protection for reverse wire connections.
- Can work with the “4-20 mA Controller/Alarm/Indicator” CT-2012, turning into a humidity controller and indicator system.
- Enables remote monitoring and control of humidity levels.
