Product Description
Overview
The Emerson KJ3242X1-EA1 (12P3162X022) is an 8-channel analog output module with integrated HART communication, designed for DeltaV M-Series control systems. It converts digital control signals from the DCS into precise 4–20 mA analog outputs, making it ideal for driving valve positioners, actuators, and variable-speed drives. Its HART capability allows simultaneous analog operation and digital device communication for advanced diagnostics and maintenance.
