ABB INICT13A

The INICT13A is an INFI-NET to computer transfer communication module for ABB Bailey INFI 90 and Symphony DCS platforms. This INICT13A serves as a dedicated gateway between the INFI-NET process control bus and upper-level host computer systems, handling bidirectional data transmission, protocol conversion and communication scheduling. It enables real-time exchange of process parameters, control commands and alarm events between field control units and supervisory operator stations, and supports Modbus RTU connectivity for third-party device integration.

This module draws power from the rack backplane at +5V DC, with an on-board dedicated communication processor to offload data handling tasks from main controllers. It is fitted with a replaceable NVRAM backup battery to retain configuration and critical data during power loss. Front-panel LED indicators show power, run, communication link and fault status for rapid on-site troubleshooting. It installs in standard Harmony / INFI 90 rack chassis, supporting hot-swap under permitted operating conditions. Configuration, commissioning and diagnostics are completed via ABB Composer / Control Builder S engineering software.

The INICT13A is widely deployed in thermal power plants, chemical processing facilities, water treatment plants and large-scale industrial DCS cabinets for system-level data interconnection. This legacy INFI 90 series module is phased out, with backward compatibility maintained on the newer Symphony Plus platform. Most available INICT13A units are tested surplus spare parts for legacy DCS cabinet overhaul and emergency communication module replacement. Firmware revision and rack compatibility must be verified before spare swap.
