301.002.001 Humidity transmitters for building automation systems, RHT

Технические характеристики:RHT relative humidity transmitters are engineered for building automation systems in the HVAC/R industry. The RHT measures relative humidity (rH), and temperature (T). RHT devices are available with large touchscreen display making configuration of the device quick and easy.

RHT devices include:
• Separate field configurable output for each measurement parameter (rH and T).
• Proportional output options including: voltage (0-10V, 2-10V) and current (4-20mA).
• Optional relay output, and Modbus communication.
