Overview

The A/CO2-R2S-CP-A10-G5 is a wall-mounted carbon dioxide sensor designed for indoor air quality monitoring and demand-controlled ventilation. It utilizes Non-Dispersive Infrared (NDIR) technology to measure CO2 levels from 0 to 2,000 ppm with an Automatic Baseline Calibration (ABC) algorithm to ensure long-term stability. The device features field-selectable analog outputs including 0-5 VDC, 0-10 VDC, and 4-20 mA, making it compatible with a wide range of Building Automation Systems.

Why Choose This Part

The sensor provides high flexibility with three different output signals and dual power compatibility for 24 VAC or 16.5 to 40 VDC systems. Its NDIR technology combined with the ABC algorithm minimizes maintenance by compensating for sensor drift over time. Additionally, the unit maintains a 3 percent accuracy rating across its standard measurement range for reliable environmental control.

Applications

Demand Control Ventilation (DCV)
Optimizing HVAC fan speeds in schools and offices based on occupancy levels to reduce energy consumption.
Indoor Air Quality Monitoring
Tracking CO2 concentrations in high-occupancy areas like auditoriums, gyms, and theaters to ensure occupant comfort.
Economizer Control
Managing outdoor air intake in commercial shopping malls and office buildings based on internal air quality benchmarks.

Getting Started

Installation involves mounting the housing to a standard junction box and wiring the power and signal lines to a controller. Configure the analog output type (0-5V, 0-10V, or 4-20mA) via the internal jumpers to match your PLC or building controller input requirements. Ensure the unit is powered within the 16.5 to 40 VDC or 24 VAC range, noting the peak power consumption of 3000mW during initialization.
