OPP-SENS® Multisensor / Multicontroller

Our new multicontroller combines three innovative product
features in one device: We combine a multisensor with a controller
function to enable intuitive parameterization via a smartphone
without the need for power or physical contact. The multisensor
and multicontroller are available in 40 variants to meet your unique
requirements. The multisensor measures three variables as standard:
temperature, relative humidity, and CO 2 . VOC is also available as an
option. These measurements are transmitted via three 1-10 volt
outputs. You can read or write all the values using the Modbus or
BACnet variant. The multicontroller sits on top of the multisensor
and rounds out the multisensor’s already diverse range of variants
by providing a controller function which can be assigned to a
measured value. In addition, an NFC display is available to further
expand the extensive NFC functionality. It enables all of the parame-
ters output by the sensor to be read in and written via a smartphone
app without the need for power or physical contact. The app can be
used to create documentation covering all the values configured in
the sensor as well as the individual designation. The corresponding
app is available in the App Store for Apple devices and the android
version is available in the Google Playstore. Furthermore, you also
have the option of either utilizing 2 analog inputs to read in the flap
setting position, for example, or to implement a relay output for
a switching function. The switching threshold can be configured
directly via the app or Modbus/BACnet.

We take a new approach with the multicontroller, integrating the
controller function into the sensor.
This eliminates the need to route the cable via the control system
and enables the multicontroller to transmit the control signal
directly to the flap.
This diagram illustrates the conventional CO 2 control process.
A CO 2 sensor supplies the measurement data to a higher-level This solution alone can save up to 60% of required cabling. In
control system, which in turn transmits the control signal to the addition, the multicontroller also analyzes the position indicator
