Emerson KJ3243X1 Communication Interface Module

Feature & Principle

It is a Series 2 PROFIBUS DP communication interface module for Emerson DeltaV DCS system. It acts as DP master station to realize data exchange between DeltaV controller and PROFIBUS DP field instruments, remote I/O and drives. It supports hot swapping without powering off the rack. Built-in bus diagnosis function, monitors bus communication status and reports fault information to DeltaV control network. Different suffix versions such as BA1, BB1, BK1 correspond to different functional configurations, widely used for process industry fieldbus networking.
