ABB AI810 Overview

The ABB AI810 (Model 3BSE008516R1) is an analog input module from the ABB Advant S800 I/O series. It is primarily used to convert analog signals from field sensors (voltage or current) into digital signals recognizable by PLC or DCS systems.

Key Features

8 input channels, each independently configurable for voltage or current input

Voltage ranges: 0 V ~ 10 V or ±10 V

Current ranges: 4 mA ~ 20 mA (also supports 0 mA ~ 20 mA)

Input impedance: approx. 290 kΩ for voltage input; 230 ~ 275 kΩ for current input (including PTC current-limiting resistor)

A/D resolution: 12 bit (some documentation specifies 16 bit), with an update rate of approximately 2 ms per channel

Operating temperature: -20 °C ~ +60 °C

Protection class: IP20

Mounting: DIN rail

Dimensions: approx. 50.8 mm × 127 mm × 114.3 mm

Weight: approx. 0.24 kg

Diagnostic functions: open-circuit detection, short-circuit protection (current input can withstand up to 30 V DC short circuit)

Typical Applications

Acquisition of analog signals from temperature, pressure, and flow sensors in process control systems

Real-time monitoring in power, petrochemical, and manufacturing automation environments

Used in conjunction with ABB AC 800M, AC 800 Series, and S800 I/O systems to provide high-precision data acquisition and fault diagnostics

Supports industrial fieldbus communication such as PROFIBUS DP and Modbus (multi-protocol support available on some versions)

Summary

In summary, the ABB AI810 is a high-precision, low-noise analog input module designed for harsh industrial environments. It is ideal for automation projects requiring multi-channel input, wide measurement ranges, and built-in self-diagnostic capabilities.
