ABB AI930

Product introduction

The AI930 is a high-performance analog input module from ABB, designed for precision measurement in industrial automation systems. As a flagship member of the S800 I/O family, it delivers exceptional accuracy for critical process variables, serving as the backbone of data acquisition in demanding environments.

AI930 integrates seamlessly with ABB’s AC800M controller, converting analog signals from sensors and transmitters into high-resolution digital data. Its 24-bit resolution and 500Hz sampling rate capture subtle process variations, making it indispensable for applications where measurement precision directly impacts product quality, safety, or efficiency.

Engineered for industrial robustness, AI930 operates reliably in extreme temperatures and electrically noisy environments, thanks to its 5kV isolation and rugged construction. This module bridges the gap between field sensors and control systems, ensuring that even the smallest signal fluctuations are detected and processed—critical for advanced process control and predictive maintenance strategies.

Core advantages and technical highlights

Ultra-high measurement precision

AI930 achieves ±0.05% accuracy at 25°C, outperforming standard analog modules. In pharmaceutical manufacturing, this precision ensures bioreactor temperatures are measured within ±0.1°C, maintaining optimal conditions for cell growth and meeting regulatory requirements. Its 24-bit resolution distinguishes 0.0001% increments of full-scale range, capturing nuances like micro-pressure changes in gas distribution systems.

High-speed data acquisition

With sampling rates up to 500Hz, AI930 excels in dynamic processes. In automotive testing, it records transient pressure spikes in hydraulic systems with 500 samples per second, capturing events that last milliseconds. This speed ensures no critical data is lost during rapid process changes, unlike slower modules limited to 50-100Hz sampling.

Enhanced noise immunity

5kV AC isolation protects AI930 from ground loops and electromagnetic interference common in heavy industry. In steel mills, where nearby motors generate EMI, it maintains stable readings from thermocouples measuring furnace temperatures—performance that unisolated modules cannot match. Advanced filtering options further reduce noise without compromising response time.

Flexible configuration

Each of AI930‘s four channels independently accepts different signal types, eliminating the need for multiple specialized modules. A single AI930 can monitor a Pt100 RTD, type K thermocouple, 4-20mA pressure transmitter, and ±10V strain gauge simultaneously—simplifying system design and reducing cabinet space requirements.

Typical application scenarios

In semiconductor fabrication, AI930 plays a critical role in chemical vapor deposition (CVD) processes. Mounted via TB820V2 terminal bases, it monitors 4-20mA signals from mass flow controllers regulating gas mixtures, ensuring precise ratios of reactive gases. Its 0.05% accuracy maintains consistent film deposition rates, directly impacting wafer yield.

AI930 captures temperature gradients across CVD chambers using type R thermocouples, sampling at 500Hz to detect hotspots that could damage wafers. This data feeds into the AC800M controller, which adjusts heating elements via AO801 modules—creating a closed-loop system that maintains ±0.1°C temperature uniformity.

In aerospace test facilities, AI930 measures strain gauge outputs (±10V) on turbine components during endurance testing. Its high resolution captures micro-deformations that signal fatigue, while fast sampling rates document transient stresses during startup/shutdown cycles—data critical for validating component lifespans.

Installation, commissioning and maintenance instructions

Installation preparation: Mount AI930 in a clean, dry control cabinet with ambient temperature between -25°C and +70°C. Use ESD protection (wristbands, mats) during handling to prevent component damage. Required tools include torque screwdrivers (0.5-0.7Nm), wire strippers (8mm strip length), and shielded twisted-pair cables (0.5-1.5mm²). Ensure proper grounding of cable shields at both ends to maximize noise immunity. Verify compatibility with the AC800M controller firmware version before installation.

Maintenance suggestions: Perform daily visual checks of AI930 status LEDs—steady green indicates normal operation, red signals faults. Calibrate semi-annually using a traceable calibrator to maintain accuracy, especially in regulated industries. Inspect terminal connections quarterly for corrosion or looseness, which can introduce measurement errors. If a channel fails, swap sensors between channels to isolate issues; replace AI930 if internal faults are confirmed, ensuring replacement retains original configuration settings. Clean with compressed air to remove dust; avoid liquids or abrasive materials.
