Bailey Infi-Net SOE Master DCS Module | ABB INSEM01

Product Description

Sequence of Events (SOE) Management Overview

The INSEM01 (Part Number: INSEM01) is a high-precision Sequence of Events (SOE) Master module designed for the ABB Bailey INFI 90 and Network 90 Distributed Control Systems (DCS). Its primary engineering function is to act as a centralized coordinator for time-stamped digital event recording. The INSEM01 (Model: INSEM01) manages the synchronization and collection of state-change data from multiple SOE input modules, ensuring that critical process trips or equipment failures are recorded with millisecond resolution. This module is essential for post-trip analysis, root cause diagnostics, and maintaining the operational transparency required in high-availability power plants and petrochemical facilities.
