NOVUS 250mm RHT Climate Relative Humidity & Temperature Transmitter Duct Mount RS485

With a wide backlit LCD and a distinctive design, the RHT Climate Relative Humidity & Temperature Transmitter NOVUS-DM RS485 is a relative humidity and temperature transmitter that provides accurate and stable measurements over a wide operating range. It calculates in real time seven psychrometric properties and all variables will be available in current or voltage retransmission or by RS485 Modbus RTU communication. The device is very versatile and allows temperature and relative humidity to be configured. Simulation and retransmission of signal generation, are useful features for fast and easy in-the-field commissioning through USB with NXperience or directly over the keyboard. The RHT Climate also has two digital alarm outputs and an embedded buzzer for sound alarm. With its accurate and stable measurements, the RHT Climate Relative Humidity & Temperature Transmitter NOVUS-DM RS485 is a versatile device that allows for temperature and relative humidity configuration. It also offers useful features such as simulation and retransmission of signal generation for fast and easy commissioning. With access to real-time psychrometric properties and various communication methods, the RHT Climate is a reliable and efficient option for HVAC professionals. Additionally, the device includes two digital alarm outputs and an embedded buzzer for sound alarms, providing even greater versatility and functionality.
