Overview

The A/CO2-R2SO-CP-A10-G5 is a wall-mounted carbon dioxide sensor designed for indoor air quality monitoring and Demand Control Ventilation (DCV). It utilizes Non-Dispersive Infrared (NDIR) technology to measure CO2 levels up to 10,000 ppm and provides selectable analog outputs including 0-5VDC, 0-10VDC, and 4-20mA. The unit operates on 24VAC or a wide DC range from 16.5VDC to 40VDC, making it compatible with most Building Automation Systems (BAS).

Why Choose This Part

This sensor features a flexible multi-output interface, allowing it to interface with diverse industrial PLC and HVAC controllers without requiring separate hardware versions. The NDIR single-beam sensing technology provides reliable long-term stability and accuracy across its 0 to 50 degrees Celsius operating range.

Applications

Demand Control Ventilation
Optimizes HVAC fresh air intake based on occupancy levels to reduce energy consumption in schools and offices.
Indoor Air Quality Monitoring
Continuous tracking of CO2 levels in hospitals, shopping malls, and theaters to ensure occupant comfort and safety.
Economizer Control
Integrates with building management systems to control dampers for free cooling or air exchange based on air quality metrics.

Key Specifications

Type Carbon Dioxide (CO2)
Output 0V ~ 5V, 0V ~ 10V, 4mA ~ 20mA
Voltage - Supply 24VAC, 16.5VDC ~ 40VDC
Operating Temperature 0degC ~ 50degC

Getting Started

Installation involves mounting the enclosure to a standard junction box and selecting the desired output signal via internal jumpers. Ensure the power supply provides at least 3W for AC operation or 0.9W for DC operation. Calibration is typically factory-set, but field verification should be performed according to local building codes using a calibrated CO2 reference meter.

Also Consider

SCD41 SENSensirion AG - A compact, surface-mount photoacoustic CO2 sensor for designs requiring direct PCB integration rather than a wall-mount housing.
SHT31 SENSensirion AG - Consider this if humidity and temperature monitoring are also required in the same environment, though it lacks CO2 sensing capabilities.
