ABB UAD155A0111 3BHE029110R0111

Product introduction

The UAD155A0111 3BHE029110R0111 is a high-precision analog input module from ABB, designed to convert and process a wide range of continuous physical signals into digital data for industrial control systems. As a key component in ABB’s measurement and control portfolio, this module serves as a critical interface between field sensors (such as pressure transmitters, temperature probes, and level sensors) and central controllers like the 3BHE024577R0101 PPC907BE AMC34 processor module, ensuring accurate and reliable data acquisition in complex automation environments.

Unlike standard analog modules, the UAD155A0111 combines exceptional measurement accuracy with robust isolation and flexible configuration, making it ideal for applications where precision is paramount—from pharmaceutical batch processing to turbine control in power plants. Whether deployed in harsh industrial settings or laboratory-grade environments, this module delivers consistent performance, enabling precise process control and real-time monitoring.

Core advantages and technical highlights

Ultra-high measurement accuracy: With ±0.02% full-scale accuracy for 4-20 mA signals and ±0.05°C for thermocouples, the UAD155A0111 outperforms most industrial analog modules, making it suitable for critical applications like semiconductor manufacturing. In a pharmaceutical reactor system, this precision ensures temperature measurements remain within ±0.1°C of the setpoint, maintaining strict compliance with FDA regulations for drug production. The module’s low drift (<20 ppm/°C) further ensures stability across temperature fluctuations, eliminating the need for frequent recalibration.

16-channel density with individual configuration: Each of the 16 channels can be independently configured for different signal types without hardware modifications, allowing the module to simultaneously process inputs from pressure transmitters (4-20 mA), RTD temperature sensors (Pt100), and voltage-based level sensors (0-10 V). In a water treatment plant, this flexibility enables the module to monitor 8 different flow rates, 4 pH levels, and 4 turbidity sensors using a single unit—reducing backplane space by 50% compared to using multiple specialized modules.

Advanced isolation and noise immunity: Equipped with 2.5 kV AC channel-to-channel isolation and 5 kV AC isolation from the backplane, the UAD155A0111 effectively rejects electromagnetic interference (EMI) and ground loops common in industrial environments. In a steel mill, this isolation ensures accurate current measurements from furnace pressure sensors despite nearby high-voltage motors and arc welding equipment, preventing measurement errors that could lead to process instability.

High-speed sampling and data processing: With a 20 Hz simultaneous sampling rate per channel, the module captures rapid signal changes—critical for dynamic processes like chemical reactions or turbine acceleration. In a gas turbine control system, this allows the UAD155A0111 to detect pressure spikes within 50 ms, enabling the PPC907BE AMC34 processor to adjust fuel flow and prevent compressor surge. The module’s onboard signal conditioning (including filtering and linearization) further enhances data quality before transmission to the controller.

Seamless system integration: Designed for compatibility with ABB’s AC800M/S800 backplanes, the UAD155A0111 integrates seamlessly with power distribution modules like the PPD513A25-111615 and communication interfaces such as the CI930F 3BDH001010R0005. It supports hot swapping, allowing replacement without system shutdown—a critical feature in continuous processes like oil refining. Diagnostic data (including channel faults and signal quality) is transmitted to the controller, enabling predictive maintenance and reducing downtime.

Typical application scenarios

In a combined cycle power plant, the UAD155A0111 3BHE029110R0111 monitors key parameters of the steam turbine: including exhaust temperature (K-type thermocouples), bearing vibration (4-20 mA accelerometers), steam pressure (4-20 mA transmitters), and oil viscosity (RTD sensors). Its high accuracy ensures turbine efficiency calculations are within ±0.1%, optimizing fuel consumption. The module’s 5 kV isolation protects measurements from generator noise, while its wide operating temperature range (-40°C to 70°C) withstands the thermal extremes of turbine enclosures.

In a food and beverage pasteurization line, the module processes data from 12 Pt100 RTDs measuring product temperature at various stages and 4 pressure sensors monitoring heat exchanger performance. Its fast sampling rate (20 Hz) ensures the PPC907BE AMC34 controller can adjust heating elements within 100 ms if temperature deviates from the 72°C target, preventing under-pasteurization or overheating. The isolated channels eliminate cross-talk between sensors, ensuring accurate readings even with wet cleaning (when used with IP65 junction boxes).

Installation, commissioning and maintenance instructions

Installation preparation: Mount the UAD155A0111 3BHE029110R0111 into a compatible S800 backplane using the front-panel screw, torquing to 0.5 Nm. Ensure at least 50mm clearance for ventilation. Connect field sensors using shielded twisted-pair cable (0.5-1 mm²), grounding shields at the module end. For thermocouples, use dedicated thermocouple wire to minimize measurement errors. Required tools include a torque screwdriver, wire strippers, and a calibrated multimeter. Power off the backplane during installation.

Commissioning steps: Use ABB’s Automation Builder software to configure each channel’s signal type, scaling, and filtering. For example, set a 4-20 mA channel to map 4 mA = 0 kPa and 20 mA = 1000 kPa. Perform a calibration check using a precision signal generator, verifying accuracy across 0%, 50%, and 100% of full scale. Test thermocouple channels with a reference temperature bath to confirm ±0.05°C accuracy. Save configurations to non-volatile memory and verify data transmission to the PPC907BE AMC34 processor.

Maintenance suggestions: Inspect the module quarterly for loose connections, dust accumulation, and LED status (power: green, channel faults: red). Clean ventilation slots with compressed air. Calibrate annually using traceable standards to maintain ±0.02% accuracy—critical for regulated industries like pharmaceuticals. Check isolation resistance yearly with a megohmmeter (minimum 100 MΩ at 500 V DC). If channels exhibit drift or failure, verify sensor wiring and signal integrity before replacing the module with an ABB-certified unit.
