Basic Product Identification
Model & Article Number: Model AI801, corresponding article number 3BSE020512R1.
Product Category: Analog input module, part of ABB’s Compact Product Suite, designed for the
S800L mechanical platform.
Core Purpose: Specialized in collecting 0...20 mA and 4...20 mA DC unipolar single-ended current
signals from field devices (such as transmitters), suitable for industrial scenarios requiring analog
signal acquisition (e.g., pressure, temperature, flow detection).
Core Functional Characteristics
Channel Configuration: 8 analog input channels, supporting 0...20 mA and 4...20 mA DC current
signals, with unipolar single-ended signal type.
Isolation & Protection: The 8 channels form a single group, isolated from ground to prevent cross-
interference. Each input is equipped with a PTC resistor for current limiting, protecting input shunt
resistors against up to 30 V DC; the module can withstand short circuits to transmitter supply (≥30 V
DC) without damage.
Signal Performance: Features 12-bit resolution and a maximum measurement error of 0.1%, ensuring
high-precision signal acquisition. Typical temperature drift is 50 ppm/°C (max 80 ppm/°C),maintaining
stability across temperature variations.
Signal Processing: Equipped with an analog input filter (0-90% rise time 180 ms) to suppress
interference; update cycle time of 1 ms for real-time signal transmission. NMRR (Normal-Mode
Rejection Ratio) exceeds 40 dB at 50 Hz/60 Hz, enhancing anti-interference capability.
Status & Wiring: Front-panel "S (Status)" LED indicates run or fault status, supporting diagnostics for
module errors, warnings, and channel errors. Process and power connections use detachable
connectors for easy installation and maintenance.
Key Limitations: No HART protocol support, no SOE (Sequence of Events) function, no redundancy
design, and no high integrity or intrinsic safety features.
