THD-R-C is a room-mount temperature and humidity transducer from Autonics, built for stationary ambient monitoring. It provides dual current outputs (4-20 mA) for both temperature and humidity, uses a fixed built-in sensor, and operates on a 24 VDC power supply. It supports measuring ranges from −19.9 to 60.0 °C and 0.0 to 99.9% RH, and features a compact case for indoor installation.
Features
- Room-type installation for ambient temperature/humidity monitoring
- Dual 4-20 mA analog outputs for temperature and humidity
- No display (non-indicating type) for simplified control systems
- Measuring range −19.9 to 60 °C / 0.0 to 99.9 % RH
- 24 VDC supply, IP10 protection, compact dimensions approx. 80 × 60 × 30.5 mm
