Overview

The A/CO2-R2SO-CP-A04-G5 is a wall-mounted carbon dioxide sensor designed for monitoring indoor air quality using Non-Dispersive Infrared (NDIR) sensing technology. It offers flexible integration with multi-protocol analog outputs and includes a local setpoint adjustment and override button for building automation interfaces.

Why Choose This Part

The sensor features a versatile triple-output design supporting 0-5VDC, 0-10VDC, and 4-20mA signals for compatibility with various PLC and BAS architectures. It operates on a wide input range of 16.5VDC to 40VDC (or 24VAC) and includes polarity protection to prevent installation errors.

Applications

Commercial HVAC Control
Automating ventilation systems in office buildings and schools to maintain CO2 levels below 1,000 ppm while optimizing energy efficiency.
Indoor Air Quality (IAQ) Monitoring
Continuous gas concentration tracking in high-occupancy environments like auditoriums and gyms.
Demand Controlled Ventilation (DCV)
Providing real-time feedback to controllers to adjust fresh air intake based on actual occupancy levels.

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 ABS plastic housing to a standard electrical box and selecting the desired analog output via onboard jumpers. Ensure the power supply can handle the 3W peak current at 24VDC, and allow the NDIR sensor to stabilize for accurate readings within its 0 to 2,000 ppm range.
