Overview

The A/CO2-R2-AN is a wall-mounted carbon dioxide sensor designed for indoor air quality monitoring in commercial and industrial buildings. Utilizing Non-Dispersive Infrared (NDIR) technology, it provides high-accuracy CO2 measurements with versatile analog output options including 0-5V, 0-10V, and 4-20mA to interface with various building automation systems.

Why Choose This Part

The sensor features NDIR technology for long-term stability and high accuracy (3 pct), which is critical for reducing recalibration cycles. Its triple-output design (0-5V, 0-10V, and 4-20mA) and wide input voltage range of 16.5V to 40VDC ensure compatibility with nearly any industrial PLC or HVAC controller.

Applications

Demand Control Ventilation
Optimizes HVAC energy usage by adjusting outdoor air intake based on real-time CO2 levels in high-occupancy areas like auditoriums and gyms.
Building Management Systems
Serves as a primary sensor for indoor air quality monitoring in office buildings and schools to ensure occupant comfort and compliance.
Economizer Control
Interfaces with air handling units to determine when outdoor air is suitable for cooling versus mechanical refrigeration based on CO2 setpoints.
Safety Monitoring
Provides reliable CO2 detection in confined or densely populated commercial spaces such as shopping malls and theaters.

Getting Started

When installing, ensure the sensor is mounted 4 to 6 feet above the floor in a location with natural air circulation, avoiding direct sunlight or air diffusers. Connect the power supply to the polarity-protected terminals and select the desired analog output channel to match your controller input configuration.
