Description

The Emerson DeltaV KJ1501X1-BB1 (12P0678X032) is a high-reliability System Dual DC Power Supply module designed for the DeltaV S-Series automation platform. This module provides critical power distribution for controller backplanes and I/O subsystems in demanding industrial environments, including chemical processing, oil and gas, and power generation facilities. It converts bulk DC input into regulated voltages required for logic and field operations, ensuring system availability and stability.

Features

  • Supports dual DC inputs to provide power redundancy for the DeltaV system.
  • Rated for hazardous atmosphere installations (ATEX Zone 2, II 3G Ex nA nC IIC Gc).
  • Compliant with ISA-S71.04 Class G3 standards for protection against corrosive airborne contaminants.
  • Advanced thermal management and internal current limiting to protect downstream components.
  • Designed for high-reliability operation in harsh industrial climates.

Applications

This power supply module is intended for use in DeltaV S-Series control systems. It is commonly deployed in mission-critical applications such as offshore oil platforms, mineral refineries, and large-scale chemical processing plants where continuous power delivery and environmental resilience are required.
