Description

The ABB AI02J Analog Input Module is a high-density industrial I/O module developed for the Symphony Plus distributed control system platform. It provides sixteen independently configurable analog input channels capable of processing both current and voltage signals from field instruments such as pressure transmitters, temperature transmitters, flow meters, level sensors, and analytical devices. The module supports 4–20 mA and 1–5 VDC input ranges, allowing flexible integration into a wide variety of process automation applications.

A key feature of the AI02J is its integrated HART communication capability. The module supports HART Version 5.4 devices and can retrieve both primary process values and additional diagnostic information from intelligent field instruments. Up to 24 secondary HART variables can be accessed across the module, providing enhanced visibility into instrument status, maintenance data, and process conditions without requiring separate communication hardware.

Information

Overview Manuals Application Notes Product Applications Environmental and Safety Compliance

Features:

  • 16 independently configurable analog input channels
  • HART v5.4 protocol support
  • Fast response with 100ms update rate
  • 12 to 16-bit configurable A/D resolution with polarity
  • Excellent accuracy of ±0.1% FSR
A distinguishing capability of the AI02J is its integrated HART (Highway Addressable Remote Transducer) protocol support via HART v5.4. The module contains one dedicated HART modem and can process up to 24 HART secondary variables across the 16 channels, with a maximum of 4 secondary variables per channel. This enables bidirectional digital communication with HART-capable field instruments for remote configuration, diagnostics, and device status monitoring without interrupting the primary analog signal.

The module implements robust electrical isolation with 1500 V isolation between field signals and the logic section, as well as 1 × 16 group channel isolation rated at 1500 V for 1 minute. Short circuit protection limits current to 96 mA per channel, and open circuit detection resolves within 5 seconds. Input impedance is 250 Ω in current mode and ≥250 kΩ in voltage mode.

The AI02J ABB Analog Input Module 16 Channels with HART support may still be available for purchase and support from Amikon Limited beyond End-Of-Life (EOL) by the manufacturer (OEM).

The IP20 protection rating designates it for indoor cabinet installation. LED status indicators on each channel provide real-time visual feedback for power status and signal over-limit conditions.
The module operates reliably across an extended temperature range of –40°C to +70°C and stores safely from –40°C to +85°C. Relative humidity tolerance spans 20% to 95% at 40°C in non-condensing conditions.

Pre-Installation Power Check: Cut off all system and auxiliary power supplies before touching hardware to prevent arcs.
Temperature Maintenance: Ensure the cabinet remains between -40°C and +70°C. Do not block localized ventilation channels.
Corrosion Control: If deploying in wastewater or chemical sites, verify your unit uses G3 conformal coating to survive corrosive atmospheres.

Technical notes

The module features 16 independent configurable input channels, each capable of receiving standard 4–20 mA current or 1–5 VDC voltage signals from process transmitters measuring temperature, pressure, flow, level, and other continuous process variables. Each channel incorporates high-resolution analog-to-digital conversion with 12 to 16-bit resolution including polarity, achieving an accuracy of ±0.1% full scale. The complete scan of all 16 channels updates within 100 milliseconds.
