ABB AI880A Analog Input Module 8-Channel 0-20 mA HART

Product Overview

The ABB AI880A (3BSE039293R1) is a high-performance analog input module. It belongs to the S800 I/O series. This module accepts 0-20 mA or 4-20 mA signals. It has 8 unipolar single-ended channels. The AI880A supports HART communication. It also offers redundancy and high integrity. This makes it ideal for safety-critical processes. The module is groupwise isolated from ground. It provides a 12-bit resolution. The input impedance is 250 ohms with a TY801 shunt stick. The module has a fast update cycle time of 10 ms.

Application Scenarios

The AI880A is perfect for process control systems. It works well in oil and gas industries. It is also used in chemical plants and power generation. The high integrity feature suits safety shutdown systems. Redundancy ensures uptime in critical loops. The module is compatible with ABB control systems. It can be used with MTU TU834, TU844, TU845, or TU854. The module supports marine certifications like ABS, BV, DNV, and LR.

Technical Specifications

The NMRR is greater than 40 dB at 50 or 60 Hz. The rated insulation voltage is 50 V. The dielectric test voltage is 500 V AC. Power dissipation is 2.4 W. The module consumes 45 mA on the +5 V Modulebus. It consumes max 50 mA on the +24 V Modulebus. External current consumption is 4 mA plus transmitter current. The maximum field cable length is 600 meters. The module has built-in current limiting for transmitter power.

Installation & Maintenance Guide

Mount the module on a standard DIN rail. Use the correct MTU base for wiring. Connect field wiring to the MTU terminals. Ensure the module keying code matches the base. The keying code is FD. The module width is 45 mm. The depth is 102 mm. The height is 119 mm. The module weighs 0.15 kg. Check front LEDs for status. The LEDs show Fault, Run, and Warning. The module supervises internal voltage and field power. It reports module errors and channel errors. Keep the ambient temperature below 55 degrees Celsius. For vertical mounting in compact MTU, keep it below 40 degrees Celsius. The protection class is IP20.
