TVOC controller | IP65 enclosure, PoM
Product description
Designed for Harsh Environments: This controller is specifically designed for use in harsh or outdoor environments.
Multiple Measurements: It measures temperature, relative humidity, air quality (TVOC), and ambient light levels.
Simplified Connection: It uses 24 VDC PoM (Power over Modbus), allowing both power and Modbus RTU communication via a single RJ45 socket.
Direct Control: The sensor's algorithm can directly control an EC fan, AC fan speed controller, or damper actuator via Modbus RTU.
Full Adjustability: All measurements and settings are available and adjustable through Modbus RTU.
Replaceable Sensor: The TVOC sensor element is replaceable, which simplifies maintenance.
Occupancy-Based Control: The ambient light sensor can be used to control the ventilation system based on room occupancy.
Additional specifications and description
What Does the Sensor Measure and How Does It Control the HVAC System?
This HVAC transmitter measures temperature, relative humidity, air quality (TVOC) and ambient light level. Based on the temperature and humidity measurement, the dew point is calculated. All these values are available via Modbus RTU communication. The sensor algorithm can directly control an EC fan, an AC fan speed controller or a damper actuator via Modbus RTU communication. The output value varies proportionally in function of the measured temperature, relative humidity and TVOC level. E.g. as temperature, relative humidity or CO2 level approaches their maximum limit, fan speed will increase or the damper will open.
How Is the Sensor Powered and Connected?
One RJ45 connector is all it takes to connect this sensor! Modbus RTU communication and 24 VDC power supply are connected via one UTP cable - we call it Power over Modbus or PoM. All measured values are available via Modbus RTU communication. Most 24 VDC power supplies offer protection against short circuit, overload and overvoltage. A 24 VDC supply voltage increases the safety and reliability of your installation.
This sensor doesn't require any configuration. Once installed, it is ready to use. The default settings will do for most applications. If necessary, the settings can be adjusted via Modbus RTU. For example, the temperature or relative humidity range can be adjusted via Modbus RTU. Also the light intensity of the LEDs for status indication is adjustable. The Modbus register map provides a complete overview of all adjustable settings.
What Are the Sensor's Quality and Durability Features?
The enclosure is made of high-quality r-ABS VO (UL94) plastic. This material is heat resistant, solid and offers good protection against impacts. It offers an IP65 protection against ingress of dust and water. Each sensor is calibrated and tested in our factory. We use sensor elements and components of high quality. This ensures the long-term stability and accuracy of this HVAC transmitter. To ensure optimal performance, it should be protected from direct sunlight.
