ABB AI801 3BSE020512R1 Analog Input Module
Product Introduction
The ABB AI801 3BSE020512R1 is an 8-channel analog input module in the S800 I/O family. It converts field signals—voltage or current—into digital values for high-resolution processing by ABB’s AC800M or Freelance control systems. Designed for demanding industrial environments, the AI801 offers precision measurement, robust signal conditioning, and seamless integration into distributed I/O architectures.
Brand & Series
-
Brand: ABB – a global leader in electrification and automation technologies.
-
Series: S800 I/O – ABB’s modular, hot-swappable I/O platform for process and discrete automation.
Key Applications
-
Process Automation: Monitoring tank levels, flow rates, and temperatures in chemical, petrochemical, and food & beverage plants.
-
Building Management: Collecting analog signals from HVAC sensors, energy meters, and environmental monitors.
-
Water & Wastewater: Measuring pH, conductivity, and pressure in treatment facilities.
-
Power Generation: Tracking voltage and current in generator sets, transformers, and switchgear.
-
Machine Control: Feedback from strain gauges, load cells, and analog transducers on packaging and assembly lines.
Main Advantages
-
High Accuracy: 16-bit A/D conversion yields resolution down to 0.001% of span.
-
Flexible Input Ranges: Configurable for ±10 V, 0–10 V, or 0/4–20 mA, adapting to diverse sensor types.
-
Low Noise & Drift: Advanced filtering and temperature compensation ensure measurement stability.
-
Hot-Swap Capability: Field-replaceable without interrupting the rest of the I/O bus.
-
Diagnostic Transparency: Per-channel status bits for open-circuit, over-range, and short-circuit detection.
-
Compact Footprint: Slim module profile maximizes rack density.
