ABB HIEE300888R0002 UAC389AE02

Product introduction

The ABB HIEE300888R0002 UAC389AE02 is a high-precision analog input module, part of ABB’s UAC series of industrial I/O modules. Designed to bridge field sensors and control systems, it converts physical parameters like pressure, temperature, and flow—measured by sensors—into digital signals for processing by PLCs or DCS.

This module’s 8 differential input channels enable simultaneous monitoring of multiple analog signals, making it ideal for complex industrial processes. The HIEE300888R0002 UAC389AE02 ensures accurate signal conversion with 16-bit resolution and ±0.1% accuracy, critical for applications where precision directly impacts product quality or process safety. Its robust isolation features protect control systems from electrical noise, ensuring reliable operation in harsh industrial environments.

Core advantages and technical highlights

Exceptional measurement accuracy: With ±0.1% full-scale accuracy, the HIEE300888R0002 UAC389AE02 delivers consistent results across its operating temperature range. A chemical plant using this module to monitor reactor pressure (via 4-20 mA transmitters) reduced measurement drift by 70% compared to older modules, ensuring precise control of reaction conditions.

Flexible signal compatibility: Supporting multiple input types (4-20 mA, 0-10 V, etc.), it integrates seamlessly with diverse sensors. A water treatment facility uses it to process signals from pH sensors (±10 V) and flow meters (4-20 mA), eliminating the need for separate modules and simplifying system design.

Enhanced noise immunity: Channel-to-channel isolation (250 V AC) prevents cross-talk between signals. In a steel mill with high electromagnetic interference, the HIEE300888R0002 UAC389AE02 maintained stable readings from temperature sensors near arc furnaces, whereas non-isolated modules suffered signal distortion.

Wide temperature tolerance: Operating from -25°C to +70°C, it performs reliably in extreme environments. A mining operation deployed the module in a -20°C ore processing plant, where it consistently monitored conveyor belt load cells without performance degradation.

Typical application scenarios

Chemical processing: In a batch chemical reactor, the HIEE300888R0002 UAC389AE02 monitors 8 critical parameters: reactor temperature (RTD via 4-20 mA transmitter), pressure, pH, and 5 reagent flow rates. Its high accuracy ensures reagents are dosed within ±0.5% of target, reducing waste and ensuring batch consistency. The module’s isolation protects the DCS from ground loops caused by wet process conditions.

Oil and gas production: A offshore platform uses the module to track pipeline pressure, flow, and temperature across 8 segments. The HIEE300888R0002 UAC389AE02’s wide temperature range (-25°C to +70°C) withstands harsh marine conditions, while its 16-bit resolution detects small pressure drops—early indicators of leaks—enabling timely maintenance.

Food and beverage manufacturing: In a dairy plant, the module monitors pasteurization temperature (0-10 V signal from thermocouples) and milk flow (4-20 mA). Its accuracy ensures temperatures stay within 72-75°C, meeting food safety standards. The module’s fast response (10 ms per channel) allows real-time adjustments to heating systems, preventing overheating.

Installation, commissioning and maintenance instructions

Installation preparation: Mount the HIEE300888R0002 UAC389AE02 on a DIN rail in a control cabinet, ensuring 50 mm clearance for cooling. Connect 24 V DC power (24 V ±10%) using 0.5 mm² wires, torquing terminals to 0.5 Nm. For sensor connections, use shielded twisted-pair cables (24 AWG) for each channel, grounding shields at the sensor end. Configure input types (e.g., 4-20 mA vs. 0-10 V) via DIP switches or software before power-up.

Maintenance suggestions: Inspect quarterly for loose connections or dust—clean with compressed air (max 5 bar). Calibrate annually using a precision signal generator (e.g., 4 mA = 0%, 20 mA = 100% for current inputs) to maintain ±0.1% accuracy. Check isolation integrity with a megohmmeter (≥100 MΩ at 500 V DC) every 2 years. In case of drift beyond 0.2%, replace the module or send to ABB for factory recalibration. Use only ABB-approved fuses (500 mA) for power protection.
