KJ3243X1-BB2 Emerson | DeltaV M-Series Profibus Interface

Emerson DeltaV KJ3243X1-BB2 Profibus DP Series 2 PLUS Interface Card

The KJ3243X1-BB2 (Model: KJ3243X1-BB2) is a high-performance Profibus DP Series 2 PLUS communication interface for the Emerson DeltaV™ M-series Distributed Control System (DCS). While often confused with standard analog cards, this specific "PLUS" variant is engineered to provide high-speed, deterministic integration of Profibus-compliant field devices—such as motor starters, variable speed drives (VFDs), and complex analyzers—directly into the DeltaV control network. By offloading communication processing from the main controller, the KJ3243X1-BB2 ensures that large-scale fieldbus architectures maintain sub-millisecond signal integrity and robust data throughput for mission-critical industrial automation.
