CD-W00-00-2U Johnson Controls CO2 Transmitter

Part number CD-W00-00-2U from Johnson Controls, listed in Power Supplies & Transformers. KKM Solutions quotes this part with pricing and availability confirmed per order.

Overview The Johnson Controls CD-W00-00-2U is a wall-mounted room carbon dioxide (CO2) transmitter designed to monitor indoor air quality in commercial HVAC applications. Housed in a low-profile enclosure, it utilizes an advanced dual-wavelength, single-beam silicon CARBOCAP sensor to deliver superior accuracy, reliability, and long-term measurement stability. This device is equally suited for spaces with periodic or constant occupancy, such as classrooms and hospital rooms, and can operate standalone or integrate seamlessly into a Building Automation System (BAS) to support demand-controlled ventilation (DCV) strategies. Features Advanced CARBOCAP technology provides a single-beam, dual-wavelength design for excellent stability over time and temperature. Dual-channel optics and long-term adjustment signal processing compensate for light-source drift. Self-calibration feature automatically corrects sensor drift in periodically unoccupied spaces. Versatile field-selectable output signals include 4 to 20 mA, 0 to 5 VDC, or 0 to 10 VDC. Built-in internal regulation and reverse wiring protection prevent circuit board damage. Menu-driven operation allows for easy configuration and a programmable CO2 measurement span. Specifications CO2 Measuring Range: 0 to 2,000 ppm Accuracy: Plus or minus 50 ppm + 3.0% of reading at 77 degrees Fahrenheit (25 degrees Celsius) Long-Term Stability: Less than 5.0% of full scale over 5 years Output Signals: 4 to 20 mA, 0 to 5 VDC, or 0 to 10 VDC Power Supply Range: 20 to 30 VAC (18 to 30 VDC), Class 2 Power Consumption: Less than 2.0 W average Operating Temperature Range: 23 to 113 degrees Fahrenheit (-5 to 45 degrees Celsius) Operating Humidity Range: 0 to 85% RH (non-condensing) Enclosure Dimensions: 4.72 x 3.16 x 1.22 inches (120 x 80 x 31 mm) Factory Calibration Altitude: 0 to 2,000 feet (0 to 600 m) above sea level without compensation Applications Demand Control Ventilation (DCV) systems to optimize energy savings (potential for 10% to 70% reduction in heating/cooling costs). Indoor Air Quality (IAQ) and fresh air monitoring in commercial buildings, office spaces, and schools. Rooftop air handling units and Economizer control systems. Healthcare facility environmental monitoring, including patient and hospital rooms.
