Multifunctional indoor air quality transmitters for building automation systems that use Modbus serial communication protocol
Siro-MOD is an indoor air quality transmitter with a modern design. The transmitter is available with several optional air quality sensors. The modular device can be equipped with CO2 concentration and VOC (Volatile Organic Compounds) measurements or alternatively PM (Particulate Matter) measurement, and in addition, temperature and humidity measurements. It offers easy installation and adjustment, several different model options and various output signals that are configurable separately for each measurement parameter.
The Siro-MOD series devices are available with a user interface that includes an LCD display and buttons making the configuration of the device quick and easy. An external configuration tool is necessary for commissioning preparations for Siro-MOD without the user interface. Configuration is also possible via Modbus network. Siro-MOD utilizes the industry standard NDIR measurement principle with self-calibrating ABC logicTM for CO2 measurement.
Siro-MOD series devices include:
- Several options for indoor air quality measurements (CO2, VOC, PM, rH, T).
- Field configurable outputs for selected measurements.

- Offset feature enabling field calibration for each measurement parameter (CO2, VOC, PM, rH, T).
- Optional LCD-display and buttons.
DPT-Ctrl is a multifunctional PID controller with differential pressure or air flow transmitter.
DPT-Ctrl enables to control constant pressure or flow of fans, VAV systems or dampers. Its two lined display shows the direction of the control output and the measurement value at the same time. It is possible to select either current or voltage for both the control output and the differential pressure or flow output. The optional autozero function eliminates the need for periodic manual zero point calibration.
Multifunctional differential pressure transmitters with air flow measurement and Modbus communication
DPT-MOD is a multifunctional transmitter for measuring volume flow, velocity, and static and differential pressure. The measurements can be read and the configuration done via Modbus communication. DPT-MOD requires less wiring than the traditional 3-wire transmitters because multiple devices can be connected on serial line. DPT-MOD can also be used with several different measurement probes such as FloXact™ or pitot tube, and air dampers.
DPT-MOD series devices include: • Two selectable functions: o Measure and monitor in-duct volume flow, velocity or differential pressure o Measure and monitor air flow across centrifugal fans • Multiple selectable measurement units: o Volume flow: m3/s, m3/h, cfm, l/s o Velocity: m/s, ft/min o Pressure: Pa, inWC, mmWC, kPa, mbar • Modbus communication protocol
DPT-MOD series device options offer: • AZ (autozero) function for automatic zero point calibration, eliminating the need for periodic manual autozeroing to ensure long term accuracy
Differential pressure transmitter with Modbus communication and Input terminal
The DPT-IO-MOD differential pressure transmitter for air conforms to Modbus over serial line protocol using RTU transmission mode and RS485 interface. The digital output signal is sent over Modbus enabling the DPT-IO-MOD to connect directly to a field communications network.
DPT-IO-MOD requires less wiring than the traditional 3-wire transmitters since multiple devices can be connected on serial line.
The DPT-IO-MOD includes an Input terminal that enables reading of multiple other signals such as temperature or control relays over Modbus. The Input terminal has two input channels designed to accept 0−10 V, NTC10k, Pt1000, Ni1000/(-LG), and BIN IN (potential free contact) signals. For example, DPT-IO-MOD can read values from one differential pressure measurement point and two temperature measurement points. Hence, the DPT-IO-MOD does the work of three transmitters.
