ABB Bailey INSEM11 Sequence of Events Master Module for INFI 90

Product Overview

The ABB Bailey INSEM11 is a Sequence of Events Master Module for the INFI 90 and Symphony DCS product families. It serves as the central time-keeping and event coordination unit for sequence of events (SOE) recording systems, capturing high-resolution time-stamped data from distributed digital inputs across the control network. The INSEM11 is critical for post-event analysis, fault diagnosis, and compliance reporting in power generation and industrial process applications.

Model Selection Tips

• INSEM11 = Sequence of Events Master Module
• Pair with IMSED01 digital input modules for complete SOE system
• Verify time synchronization source (IRIG-B/GPS) availability
• For standard event recording, INSEM01 may be sufficient
• Confirm MMU slot availability for SOE master module
