Description

KJ4001X1-CK1: Product Overview
The EMERSON KJ4001X1-CK1 is a central controller module for Emerson’s DeltaV™ S-series Distributed Control System (DCS). This controller acts as the computational engine of a DeltaV station, responsible for executing control strategies including continuous regulatory control, batch sequencing, and logic operations. It interfaces with I/O modules—particularly the innovative CHARM (Characterization Module) I/O cards—to read process variables from field instruments and execute control commands.
The controller is designed for the Electronic Marshalling architecture, which eliminates traditional marshalling cabinets by allowing any I/O type to be assigned via software. It provides deterministic performance essential for precise process control in demanding industrial environments.
