Overview

The A/CO2-R2O-CP is a wall-mount carbon dioxide sensor designed for indoor air quality monitoring with a standard measurement range of 0 to 2,000 ppm. It features a versatile triple-output interface supporting 0-5 VDC, 0-10 VDC, and 4-20 mA signals, making it compatible with various building automation systems and industrial controllers. This specific model includes a dry contact override for manual integration into HVAC control logic.

Why Choose This Part

The sensor employs an Automatic Baseline Correction (ABC) algorithm to minimize long-term drift and ensure accuracy of 3 percent without frequent manual calibration. Its wide supply voltage range of 16.5 VDC to 40 VDC and 24 VAC compatibility allows for flexible installation in existing industrial or commercial electrical environments.

Applications

Demand-Controlled Ventilation (DCV)
Optimizes HVAC fan speeds based on real-time CO2 levels to reduce energy consumption in commercial buildings.
Indoor Air Quality (IAQ) Monitoring
Ensures office spaces, classrooms, and hospitals maintain healthy CO2 concentrations below recommended thresholds.
Greenhouse Climate Control
Monitors CO2 enrichment levels to maximize plant growth in controlled environment agriculture.

Key Specifications

Getting Started

Wire the sensor using the polarity-protected screw terminals and select the desired output signal (VDC or mA) via internal jumpers or wiring configuration. For integration with a PLC or MCU, ensure the analog input is scaled to match the 0 to 2,000 ppm default range and the selected voltage or current output mode.
