Basic Product Identification
Model & Article Number: Model AI835, corresponding article number 3BSE008520R1.
Product Category: Analog input module, classified as spare parts, belonging to ABB’s S800 I/O
series. It is compatible with both the 800xA and Compact Product Suite control systems.
Core Purpose: Specialized in collecting thermocouple and millivolt (mV) analog signals, designed for
temperature measurement and low-voltage analog signal acquisition scenarios in industrial control
systems (e.g., temperature monitoring in chemical reactors, industrial furnaces).
Core Functional Characteristics
Channel Configuration: 8 analog input channels (no output channels), dedicated to thermocouple and
mV signal types, meeting the needs of multi-point temperature or low-voltage signal detection.
Measurement Performance: Equipped with a 15-bit A/D resolution, ensuring high-precision
conversion of weak thermocouple/mV signals for accurate data acquisition.
Isolation & Safety: Rated insulation voltage of 50 V, providing basic electrical isolation protection to
prevent interference between the module and external circuits. It does not have intrinsic safety
features.
Key Limitations: No built-in batteries; does not support intrinsic safety design; specific parameters
such as signal range, error margin, and temperature drift are not detailed in the document.
Technical Specifications
Dimensions & Weight: Net weight 0.2 kg; gross volume 1.69 dm³ (specific length/width/height not
provided, consistent with S800 I/O series module size standards).
Electrical Parameters: No specified AC/DC I/O voltage or current (focused on thermocouple/mV weak
signals); rated insulation voltage 50 V.
Compatibility & Installation
Termination Unit Compatibility: Must be used with Module Termination Units including TU810, TU812,
TU814, TU830, and TU833 for proper wiring and signal termination.
System Compatibility: Applicable to multiple versions of ABB’s S800 I/O (4.0, 4.1, 5.0, 5.1),
integrating seamlessly into 800xA and Compact Product Suite control systems.
Sensor Matching: Recommended for use with the TY820 temperature sensor (specific matching
details not specified), ensuring compatibility with common industrial temperature detection
components.
