22UTH-550X Outdoor Humidity and Temperature Sensor, Modbus RTU, Radiation Shield
Two 0-5V/0-10V outputs (temp and humidity) in addition to Modbus; ranges set over the network.
Shield keeps rain and radiated heat from roofs and nearby surfaces off the sensing elements.
Key Features
- Nominal voltage: 24 VAC/DC
- Operating condition airflow: max. 40 ft/s (12 m/s)
