RHT-WM & RHT-DM - Temperature and humidity transmitter

The microprocessor circuit allows complete configuration of the output range when used with the TxConfig PC interface and Windows® software. The humidity signal can be configured for relative humidity or dew point output. The RHT-WM model is dedicated to wall-mounted applications, while the RHT-DM version is suitable for duct and wall applications.

• Power: 12 Vdc to 30 Vdc (4-20 mA model) or 18 to 30 Vdc (0-10 V model)
• Output: powered two-wire loop 4-20 mA or 20-4 mA
• Output voltage: 0-10 Vdc (optional)
• Isolation between outputs
• Isolated 4-20 mA outputs
