Description

KJ2201X1-PW1: Product Overview
The EMERSON KJ2201X1-PW1 is a power supply module designed for Emerson’s DeltaV™ S-series Distributed Control System (DCS). This module serves as the primary power source for DeltaV controller chassis and I/O modules, converting AC mains voltage to regulated DC power required for system operation. Installed in a DeltaV power supply slot, its primary function is to provide clean, stable power to all system components while supporting hot-swap replacement and redundant configuration for maximum system availability.
The power supply features advanced monitoring and diagnostics capabilities, communicating its status to the DeltaV system for proactive maintenance. The robust design ensures reliable operation in industrial environments, with protection against over-voltage, over-current, and over-temperature conditions. The module’s hot-swap capability allows for replacement without system shutdown when used in redundant pairs.
