Overview

The A/CO2-R2SO-AN-A03-G5 is a wall-mounted carbon dioxide sensor designed for indoor air quality monitoring with integrated setpoint and override controls. It supports a wide input voltage range from 16.5 VDC to 40 VDC and features versatile triple-analog output options including 0-5 VDC, 0-10 VDC, and 4-20 mA. The unit utilizes Automatic Baseline Correction (ABC) software to maintain accuracy over time without manual calibration in typical occupancy environments.

Why Choose This Part

This sensor offers exceptional flexibility with field-selectable 0-5 VDC, 0-10 VDC, and 4-20 mA outputs and is protected against polarity reversal. The inclusion of an integrated setpoint and override function allows local user interaction with the HVAC system within a single, aesthetically neutral wall-mounted enclosure.

Applications

Commercial HVAC Control
Used in office buildings and schools to drive Demand Controlled Ventilation (DCV) based on occupancy levels.
Institutional Air Quality Monitoring
Ideal for auditoriums and large meeting spaces where CO2 levels can rise rapidly during events.
Smart Building Automation
Integrates with Building Management Systems (BMS) via standard analog signals to optimize energy efficiency and occupant comfort.

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 requires a 24 VAC or 16.5 to 40 VDC power source; ensure the ABC software is allowed to calibrate by exposing the sensor to fresh air levels periodically. Connect the appropriate analog output terminal to your PLC or BMS controller's analog input card and configure the scaling for the 0 to 2,000 ppm range.
