ABB AI03

ABB AI03 is an 8-channel analog input module in the ABB Ability Symphony Plus series. It is primarily used in industrial automation and process control systems (such as DCS and PLC) to acquire analog signals—such as temperature, pressure, and level—and convert them into digital signals for controllers or host systems.

Key Features

Channels and Signal Types

8 channels, each capable of receiving multiple types of analog signals, including:

RTD (2/3/4-wire)

Voltage (0–10 V)

Current (4–20 mA)

Thermocouples

Supports various RTD types, including 100 Ω platinum, 120 Ω nickel, and 53 Ω copper.

Accuracy and Resolution

16-bit A/D conversion, resolution 0.1% FSR, measurement error ≤ ±0.1%.

Automatic calibration and compensation ensure high accuracy across wide temperature ranges.

Response and Scan Rate

All 8 channels update within 450 ms, suitable for real-time monitoring applications.

Electrical and Environmental Specifications

Operating voltage: 220 V (some versions support 24 V DC), power consumption approx. 10 W.

Operating temperature: –40°C to +70°C (some documents list –20°C to +60°C).

Protection rating: IP20–IP54, suitable for harsh industrial environments.

Interfaces and Compatibility

Parameter configuration via ABB FC 221/FC 222 function blocks.

Fully compatible with the Symphony® Plus DCS I/O device structure.

Supports multiple communication protocols such as Modbus TCP/IP, Modbus RTU, and CANopen.

Typical Applications

Used in industries such as power generation, oil & gas, chemicals, pharmaceuticals, building automation, and energy management for monitoring process variables including temperature, pressure, level, and flow.

Summary

The ABB AI03 offers high channel density, wide signal compatibility, and precise 16-bit A/D conversion. Combined with automatic calibration and fast response, it provides reliable analog signal acquisition in industrial environments, making it a widely used analog input module within the ABB Ability™ Symphony® Plus system.
