The CO2 regulator MODBUS is a combined sensor and regulator for a wide range of applications. For full control of ventilation in offices and/or as CO2 sensor in more complicated ventilation systems.
It is provided with two independent 0-10V outputs. A proportional output based on the current CO2 level, and one control output designed for control of damper or ventilation plant. Room temperature can be included as a control parameter. The MODBUS interface makes it possible to retrieve data and measured values from the unit.
Both design and ease-of-use have been prioritised
- Easy to set-up, install and adjust.
- Maintenance free.
- Discreet sensor ideal for mounting in households and office environments.
- Control of ventilation plant based on temperature and CO2 level.
- Possible to adjust on the basis of CO2 level alone.
- Possible to use as CO2 meter and ventilation controller simultaneously.
- PID (proportional-integral-derivative) adjustment
- Two output control signal ranges available: 0 – 10V or 2 – 10V.
- Digital reading of measured values via MODBUS interface.
If on/off operation is required, the 24V DC power supply type PowerSupply 0.1-24 E with integrated setpoint relay is ideal to use together with the sensor.
CO2 Sensor, modbus uses the widely used ABC algorithm, which ensures long life without calibration. Only the room cannot be used constantly, but must regularly get sufficient airflow to lower the CO2 to fresh air level.
