ABB UAC383AE01
Product Introduction
The ABB UAC383AE01 is a high-density analog input module for ABB’s AC 800M distributed control system, delivering precision measurement for critical process variables. Engineered for hazardous environments, this 8-channel module provides configurable voltage/current inputs with industry-leading ±0.1% accuracy. The UAC383AE01 integrates seamlessly into System 800xA architectures, enabling real-time monitoring of temperature, pressure, flow, and analytical instruments while supporting HART 7 digital communication for smart device diagnostics.
As part of ABB’s S800 I/O family, the UAC383AE01 features galvanic isolation exceeding 1500V AC, eliminating ground loops in electrically noisy industrial settings. Its hot-swappable design allows maintenance without system shutdown, while SIL 2 certification ensures compliance for safety applications. The module serves as the sensory backbone for process automation, converting raw field signals into actionable data for ABB’s AC 800M controllers with deterministic sub-millisecond latency.
Core Advantages and Technical Highlights
Measurement Precision:
The ABB UAC383AE01 achieves ±0.1% accuracy through 16-bit sigma-delta ADCs with automatic temperature compensation (-25°C to +70°C). Integrated noise filtering rejects 100 dB of common-mode interference at 50/60 Hz.
HART Integration:
Native HART pass-through enables simultaneous analog signal acquisition and digital diagnostics from smart transmitters without separate multiplexers. Configuration via Control Builder M eliminates manual ranging switches.
Safety and Robustness:
SIL 2 certification supports safety instrumented functions (SIF) with hardware fault tolerance. ATEX/IECEx Zone 2 approval allows deployment in explosive atmospheres. Conformal coating protects against humidity and corrosive gases.
Engineering Efficiency:
Automatic channel configuration detects signal type (voltage/current) during commissioning. LED per channel indicates signal health, overrange, and HART communication status. Backward compatible with UAC381AE01 wiring schemes.
Typical Application Scenarios
In oil refineries, the ABB UAC383AE01 monitors catalytic reactor temperatures with 0.1°C resolution, triggering safety interlocks via SIL 2 logic when exceeding thresholds. HART diagnostics predict thermocouple drift months in advance.
Pharmaceutical bioreactors utilize its 4-20mA inputs for pH/DO probe monitoring, while HART communication calibrates smart sensors during sterile operation. The module’s 1500V isolation prevents ground loops in ISO Class 5 cleanrooms.
Power plants deploy the UAC383AE01 for generator winding temperature surveillance, sampling 32 points per rack across redundant modules. Its -25°C cold-start capability ensures reliability in substation outdoor cabinets.

Installation, Commissioning and Maintenance Instructions
Installation Preparation:
Ensure ambient humidity <95% non-condensing. Ground DIN rail to <1 Ω using 6 AWG cable. Handle module by edges using ESD wrist strap. Required tools: Torx T15 screwdriver, ABB Control Builder M V11+. Mount UAC383AE01 with adjacent slots empty for heat dissipation.
Maintenance Suggestions:
Quarterly: Verify calibration via Control Builder M (drift >±0.2% requires recalibration). Annually: Clean terminals with isopropyl alcohol; inspect conformal coating for cracks. Replace after 5 years of continuous operation. For HART device management, use ABB Field Information Manager (FIM) software. Store channel configuration on SD card.
