ABB AI810 3BSE008516R0001 Analog Input Module
1. Introduction
The ABB AI810 3BSE008516R0001 is a 16-channel analog input module designed for ABB’s S800 I/O and AC 800M control systems. It provides high-precision signal acquisition from field transmitters, converting analog signals such as 0–20 mA or 4–20 mA into digital data for process control applications. The AI810 module is widely used in process automation systems that demand accurate measurement, stable performance, and high reliability in harsh industrial environments.
2. Technical Specifications
This analog input module supports 16 isolated channels, each capable of handling current signals within a standard industrial range (0–20 mA / 4–20 mA). The module operates at 24 V DC nominal voltage supplied via the I/O system bus, consuming around 1.5 W.
It features 12-bit resolution for precise signal conversion and incorporates input filtering to minimize electrical noise. The AI810 provides galvanic isolation between channels and the ModuleBus, ensuring measurement integrity. It operates effectively within a temperature range of 0°C to +55°C and can be stored safely between –40°C and +70°C.
The module communicates directly with the AC 800M controller via the ModuleBus, allowing seamless integration with ABB’s 800xA automation system. Diagnostic LEDs on the front panel provide real-time status for power, communication, and channel health.

3. Structure and Composition
The AI810 consists of:
A signal conditioning board with 16 analog input circuits
A terminal base unit (TU810/TU812) for wiring and mounting
Front-mounted LEDs for operational status and fault indication
A hot-swappable design, allowing module replacement without system interruption
This modular structure supports flexible expansion and simplifies maintenance in large control installations.
