ABB IMSER02 Bailey Infi 90 Sequence of Events Recorder Module

Description

The ABB IMSER02 is a high-precision Sequence of Events (SOE) Recorder module designed for the Bailey Infi 90 and Network 90 Distributed Control Systems (DCS). Its primary function is the millisecond-accurate capturing and time-stamping of discrete state changes from field devices. This module is essential for post-trip analysis, root cause diagnostics, and complex event monitoring in power plants and heavy industrial facilities where the chronological order of rapid digital transitions is critical for safety and operational assessment.

Features

• High-Resolution Event Logging: Captures digital transitions with 1ms precision, allowing operators to distinguish between events occurring in extremely rapid succession.

• Buffer Management: Features internal memory buffers to ensure no event data is lost during periods of high signal activity or burst conditions.

• System-Wide Clock Synchronization: Works in tandem with the IMCKN01 clock module to ensure all recorded events across multiple racks are synchronized to a single master time source.

• Robust Signal Isolation: Incorporates advanced electrical isolation to prevent field transients from affecting the system bus or data integrity.

• Predictive Maintenance Support: Provides the granular data necessary for identifying intermittent relay chatter or early-stage equipment failures before they result in a full system trip.
