Product Introduction
The ABB Bailey IMSED01 is a Sequence of Events (SOE) Digital Inputs Module, designed for precise event capturing and real-time data logging within industrial automation systems. As part of the ABB INFI 90 or Symphony series, the IMSED01 is tailored to monitor and timestamp the status changes of digital signals with millisecond-level accuracy. It plays a critical role in providing chronological evidence of operational events, alarms, and system transitions, especially in power generation, petrochemical, and manufacturing sectors.
This module supports integration into complex DCS (Distributed Control System) environments, allowing engineers and operators to trace sequences, analyze faults, and ensure compliance with safety and operational protocols.
