This manual covers the Autonics THD series temperature and humidity transducers, including specifications, installation, wiring diagrams, and Modbus RTU…
The document provides a comprehensive overview of the Autonics THD Series Temperature/Humidity Transducer. It details various models (THD-R-PT through THD-WD) with different mounting types (Room, Duct, Wall), sensor lengths, and output modes including DC 4-20mA, 1-5VDC, and RS485 Modbus RTU communication.
| Power supply | 24VDC (Allowable range: 90 to 110% of rated voltage) |
|---|---|
| Measuring input | Temperature (Built-in sensor), Humidity (Built-in sensor) |
| Measurement range (Temp.) | -19.9 to 60.0 ℃ |
| Measurement range (Humidity) | 0.0 to 99.9%RH |
| Accuracy (Temp.) | Max. ±0.8 ℃ +1.0℃ (at room temperature) |
| Communication speed | 1200 to 115200bps |
The allowable impedance of current output is max. 600Ω.
Divide the read 16-bit value by 100 (e.g., 2480 / 100 = 24.80 ℃).
The effective communication distance is max. 800m.
