CDS201 - CO2, Temperature and Humidity Room Transmitter - DESCRIPTION 
by E+E Elektronik

The CDS201 is optimized for demand controlled ventilation and building automation in residential and commercial applications.

The CDS201 combines CO2, temperature (T) and relative humidity (RH) measurement in one device with modern design and state-of-the-art technology.

Outstanding Measurement Performance

The CDS201 incorporates the E+E dual wavelength NDIR CO2 sensor, which compensates for aging effects, is highly insensitive to pollution and offers outstanding long-term stability. A multiple point CO2 and T factory adjustment procedure leads to excellent CO2 measurement accuracy over the entire T working range.

Outputs and Digital Interface

CDS201 features analogue outputs or RS485 interface. Beside CO2, RH and T, the dewpoint temperature Td is also available via Modbus RTU or BACnet MS/TP.

Functional Design, Cost-saving Installation

The elegant enclosure is available in two sizes according to regional standards and features an optional display. The back cover contains just the push-in spring terminals, it can be mounted and wired without the front cover containing the electronics. Thus, the active part of the device is not exposed to construction site pollution and can be simply snapped onto the back cover right before commissioning. Besides, the active part can be replaced without tools within seconds.


The digital version with RS485 interface can be set up and configured via PC with the free PCS10 Product Configuration Software and an optional configuration adapter.
