The ABB HEIE420158R0001 XT 376A-E buffer module is a core auxiliary component designed specifically for Tricon 

controllers, primarily responsible for the temporary storage and processing of sequence of events (SOE) data. Working 

in conjunction with the main processor and communication module, this module captures the state changes (i.e., "events") 

of discrete variables in the system in real time and synchronously stores the event states along with precise timestamps in 

a built-in buffer, providing crucial data support for fault tracing and process analysis in industrial control systems. Its 

compact design is highly compatible with the Tricon v9-v10.x series systems, allowing seamless integration into existing 

industrial control architectures, and is suitable for scenarios with stringent requirements for event response speed and data 

reliability.

Moore Automation delivers high-quality industrial parts and equipment with competitive pricing and reliable availability. 

With an extensive inventory and fast delivery cycles, we ensure that your critical components are ready when you need 

them most. Our commitment to excellence and customer satisfaction makes us your trusted partner in maintaining
