Product introduction
The ABB A02040-URAS14 is a high-precision gas analyzer sensor module designed for industrial gas monitoring applications, part of ABB’s renowned URAS series of gas analysis solutions. This module integrates advanced infrared (IR) sensing technology to deliver accurate and reliable gas concentration measurements in demanding industrial environments.
ABB A02040-URAS14 is engineered to detect a wide range of gases, including carbon dioxide (CO₂), methane (CH₄), and other hydrocarbon gases, making it versatile across multiple industries. As a critical component in gas monitoring systems, ABB A02040-URAS14 provides real-time data to ensure process safety, regulatory compliance, and operational efficiency, serving as the “sense organ” in industrial automation networks.
Core advantages and technical highlights
Superior measurement accuracy: ABB A02040-URAS14 utilizes dual-beam infrared technology to minimize drift and maintain precision even in fluctuating environmental conditions. With a typical measurement error of less than ±1% of full scale, it outperforms many conventional gas sensors, ensuring reliable data for critical decision-making.
Broad gas compatibility: Unlike single-gas sensors, ABB A02040-URAS14 can be configured to measure multiple gases through software adjustments, eliminating the need for hardware changes when monitoring requirements evolve. This flexibility reduces inventory costs and simplifies system upgrades.
Robust environmental resistance: The ABB A02040-URAS14 features an IP65-rated housing that protects internal components from dust, water jets, and chemical splashes—common in industries like chemical processing and wastewater treatment. Its stable performance across -10°C to +50°C ensures consistent operation in both indoor and outdoor installations.
Seamless system integration: Equipped with both 4-20 mA analog output and RS485 communication, ABB A02040-URAS14 easily connects to PLCs, DCS systems, and SCADA platforms. It is fully compatible with ABB’s AC 800M controllers and System 800xA, enabling end-to-end automation solutions with centralized data management.
Typical application scenarios
In chemical manufacturing plants, ABB A02040-URAS14 plays a vital role in monitoring gas concentrations in reaction vessels and exhaust streams. Its fast response time (≤2 seconds) ensures rapid detection of hazardous gas leaks or process deviations, triggering safety interlocks to prevent accidents and environmental contamination.
Within power generation facilities, ABB A02040-URAS14 monitors flue gas emissions to ensure compliance with environmental regulations. By continuously measuring CO₂ and other pollutants, it helps plant operators optimize combustion efficiency while meeting emissions targets, reducing both environmental impact and operational costs.
In food and beverage production, ABB A02040-URAS14 controls modified atmosphere packaging (MAP) processes by monitoring gas mixtures (e.g., CO₂ and N₂) to extend product shelf life. Its high accuracy ensures consistent package quality, reducing waste and maintaining product freshness throughout the supply chain.

Installation, commissioning and maintenance instructions
Installation preparation: Before installing ABB A02040-URAS14, select a location with minimal vibration and away from direct sunlight or heat sources. Ensure the mounting surface can support 5x the module’s weight (approximately 1.5 kg). Required tools include a Phillips screwdriver, torque wrench (set to 2.5 Nm), and cable strippers. Use shielded cables for electrical connections to prevent electromagnetic interference. Verify that the 24 V DC power supply is isolated and protected by a 0.5A fuse. Allow at least 100 mm of clearance around the module for ventilation.
Maintenance suggestions: For optimal performance of ABB A02040-URAS14, perform a functional check monthly, verifying output signals against a known gas standard. Clean the optical window quarterly using a lint-free cloth with isopropyl alcohol to prevent measurement drift. Conduct full calibration every 6 months using ABB-approved calibration gases. If sensor drift exceeds 2% of full scale, recalibrate immediately. Store spare ABB A02040-URAS14 modules in their original packaging in a dry environment (15°C to 30°C) with relative humidity below 70%. When replacing the module, ensure the process is depressurized and gas-free to avoid safety risks.
