The GWNMXX is a gas sensor that has a 24VAC/DC, 50/60 Hz electrical rating with -20° to 50°C (-4° to 122°F) operating temperature range and 0-90% RH (non-condensing) humidity range.  It has a 0.5-0.6 N-m (0.37-0.44 ft-lb) torque range and IP20 protection class.  The unit has CE marking.

The gas platform is ideal for applications such as controlling parking garage ventilation, commercial buildings & factories, monitoring air quality in vehicle bays, mechanical rooms, and sally ports.  It has three colored LEDs that provide easy status viewing, while its microprocessor control ensures excellent stability and no calibration requirements. The unit has 4-20mA output and relay interface, which supports multi-stage fan actuation and service indications.

The unit is easy to install and can be mounted in any single-gang electrical box.  The sensor is designed to be modular, allowing for easy sensor replacements without removing the platform.  The GWNMXX and AG01 Sensor Modulator must be purchased together as direct replacements for the GWMAS CO Sensor

The AG01E CO sensor module and AG02 NO2 sensor module accessories are also available.
