Schneider SpaceLogic SCD2XAXXVX Duct CO2 VOC Sensor Analog 24V
The SpaceLogic SCD2XAXXVX is an economical yet high-precision duct-mounted sensor engineered specifically to monitor chemical air quality and occupant-driven odors. This specialized analog-output device focuses on capturing Carbon Dioxide (CO2) concentrations and Volatile Organic Compound (VOC) index variables.
Product Overview
Outfitted with dual independent analog outputs that can be individually configured for voltage (0-5V/0-10V) or current (4-20mA) signals, the SCD2XAXXVX seamlessly interfaces with legacy, non-networked Building Automation Systems (BAS). It is highly sought-after by facility managers looking to comply with ASHRAE 62.1 commercial ventilation standards during building retrofits and renovations.
Technical Specifications
Protocol / Communication
None. Pure analog hardwired outputs for seamless integration with legacy DDC panels.
I/O Points & Signals
2 independent analog outputs
Outputs individually configurable via board-level jumpers/DIP switches
4 to 20 mA (current loop, max load 500Ω)
0 to 5 VDC / 0 to 10 VDC (voltage outputs, min load 10kΩ)
Output 1: CO2
Output 2: VOC (eCO2 equivalent or relative air quality index)
Power Supply / Voltage
Current loop mode: 12 to 30 VDC
Voltage mode: 24 VAC ±15% (50/60 Hz) or 15 to 30 VDC
Max power usage: 100mA @ 24V
Sensor Parameters & Accuracy
CO2 Sensing: Self-calibrating NDIR sensor with dual-wavelength technology. Range: 0 to 2000 ppm. Accuracy: ±30 ppm ±3% of reading.
VOC Sensing: Multi-pixel metal oxide gas sensor. Highly sensitive to organic odors, carbon monoxide, alcohols, formaldehyde, and hydrocarbons. Output maps to standard 0-100% full-scale voltage or current.
Regulatory & Certifications
CE, FCC Part 15 Class B, RCM, RoHS, WEEE, meets ASHRAE 62.1-compliant HVAC guidelines.
Enclosure & Material
IP65 housing. Rugged polymer construction with an adjustable-depth duct insertion probe and integrated airtight neoprene mounting gaskets.
Typical Applications
ASHRAE 62.1 Standard Compliance: Deployed in return air ducts of older schools, universities, and commercial spaces to feed dual CO2/VOC analog values directly to vintage DDC automation systems.
Laboratory & Exhaust Shaft Ventilation: Installed in science labs and light manufacturing exhaust vents to monitor organic solvents and trigger booster exhaust fans when chemical VOC levels exceed safe thresholds.
Retail & Restaurant Commercial Kitchens: Tracks occupant CO2 load and cooking-related organic vapor off-gassing to automatically scale kitchen hood exhaust rates.
Note: This sensor is specifically designed for integration with legacy building automation systems through pure analog outputs, making it ideal for retrofit applications where network connectivity is not available.
