Description  The C7232A1008 is a wall-mounted CO₂ sensor designed for use in HVAC systems and building automation applications. It monitors carbon dioxide concentration using non-dispersive infrared (NDIR) technology and provides both analog and relay outputs for integration with ventilation control strategies.   Technical Specifications  Condition New/Never Used Surplus Brand Honeywell Category Sensors & Switches Part Number C7232A1008 Subcategory CO2 Sensor Sensor Technology Non-dispersive infrared (NDIR) Output Type 0/2–10 VDC, 0/4–20 mA (jumper-selectable) Relay Output SPST, closes at 800 ppm (selectable), 1A @ 24 VDC/50 VAC Supply Voltage 24 VAC ±20%, 50/60 Hz; 24 VDC ±20% Measurement Range 0–2000 ppm CO₂ ±5% or ±50 ppm Accuracy ±30 ppm + 2% of reading Calibration Interval 5 years Response Time 2 minutes Operating Temperature 32° to 122°F (0° to 50°C) Operating Humidity 0% to 95% RH non-condensing Mounting Type Wall mount (standard) or duct mount (optional) Enclosure Rating NEMA 1 (wall), NEMA 3 (duct); UL 95-5V flammability Display Optional 4-digit LCD Wiring Terminations 20 AWG cable (8" and 6" lengths) Approvals UL File #E4436, CE Weight 0.18 lbs       Information About C7232A1008 The C7232A1008 is a Honeywell CO₂ sensor built for indoor air quality management through precise monitoring of carbon dioxide levels. It utilizes gold-plated NDIR technology for accurate and long-term sensing stability and includes selectable voltage or current outputs to match a variety of control systems. Featuring an SPST relay output and optional LCD, the sensor can activate ventilation equipment when CO₂ levels exceed a user-defined threshold. This model supports both wall and duct mounting (NEMA 1 and NEMA 3 enclosures respectively) and is suitable for integration into HVAC or building automation systems. Key Features: NDIR CO₂ Measurement: Uses non-dispersive infrared technology for precise gas sensing. Long-Term Calibration Stability: Gold-plated sensor construction ensures minimal drift over time. Output Flexibility: Selectable 0/2–10 VDC or 0/4–20 mA analog signal outputs. Relay Activation: SPST relay output closes at 800 ppm CO₂ (adjustable), ideal for DCV systems. LCD Display Option: 4-digit display provides real-time CO₂ level and system status. Automatic Background Calibration: ABC algorithm minimizes zero-drift maintenance needs. Wide Measurement Range: Detects CO₂ concentrations from 0 to 2000 ppm. Fast Response Time: Measures changes in CO₂ within 2 minutes. Rugged Enclosure: Rated NEMA 1 for wall mount and NEMA 3 for duct mount; UL 95-5V flammability rating. Reliable in Harsh Conditions: Operates from 0–50°C and 0–95% RH non-condensing. The C7232A1008 delivers the precision, durability, and adaptability needed for indoor environmental monitoring in HVAC control systems.
