EMERSON KJ4001X1-BE1 12P0818X072 REV:L

Description

Product Overview

The EMERSON KJ4001X1-BE1 12P0818X072 REV:L is a high-density, analog and digital I/O module designed for the DeltaV distributed control system (DCS). This specific module, part of the DeltaV S-series, functions as a CHARM (CHARacterization Module) I/O card that provides a configurable mix of input and output channels in a single, compact unit. The EMERSON KJ4001X1-BE1 is engineered for direct connection to field devices, offering exceptional flexibility and reducing cabinet space in process automation applications.

Key Product Parameters

• Product Type: CHARM I/O Card (Combined Hybrid Analog & Remote Multiplexer)

• Compatible System: Emerson DeltaV S-Series DCS

• Part Number: KJ4001X1-BE1 (12P0818X072 is likely a manufacturing or lot code, REV:L indicates hardware revision L)

• I/O Type: Configurable for a mix of analog inputs (AI), analog outputs (AO), digital inputs (DI), and digital outputs (DO). The exact channel count and type are defined by the plugged-in CHARM cartridges.

• Channels: Typically supports up to 8 channels, each independently configurable via its own plug-in CHARM cartridge.

• Communication: Interfaces with the DeltaV controller via a dedicated, high-speed I/O network.

• Isolation: High levels of channel-to-channel and field-to-system isolation provided by the individual CHARM cartridges.

• Power: Powered directly from the DeltaV system’s marshalling cabinet or field power supply.

Advantages and Core Features

The primary advantage of the EMERSON KJ4001X1-BE1 lies in the revolutionary CHARM technology. Each channel is configured by a small, plug-in cartridge that defines its function (e.g., 4-20mA input, RTD input, discrete output), allowing for unprecedented flexibility and late binding in system design. This modularity drastically simplifies engineering, spares management, and field changes. The module offers intrinsic safety (IS) options via specific CHARMs for hazardous areas. The design of the KJ4001X1-BE1 emphasizes ease of use, diagnostic capability (per-channel LED status), and high reliability, which are hallmarks of the DeltaV system.

Application Scenarios

This module is used across all continuous and batch process industries for versatile signal interfacing:

• Chemical & Petrochemical Plants: Connecting a mix of temperature transmitters (RTD), control valve positioners (AO), pressure transmitters (AI), and solenoid valves (DO) on a single unit operation.

• Pharmaceutical & Biotech: Interfacing with bioreactor sensors (pH, DO, temp) and control elements for precise batch process control.

• Oil & Gas Production: Managing signals from wellhead pressure/temperature sensors and associated shutdown valves on offshore platforms.

• Food & Beverage: Handling inputs from flow meters and temperature probes while controlling modulating valves and pump starters on processing lines.

Comparison with Competing Products

Competing DCS offerings from Siemens (PCS 7 with ET 200SP), ABB (Symphony Plus/800xA), and Yokogawa (CENTUM VP) use traditional, function-specific I/O cards. The EMERSON KJ4001X1-BE1, with its CHARM-based architecture, offers a distinct advantage in flexibility and inventory reduction. A single KJ4001X1-BE1 card can replace several fixed-function cards from competitors, reducing spare part counts and allowing last-minute signal type changes without hardware rewiring. This approach represents a significant shift towards software-configured, universal I/O.

Selection Guide and Important Notes

Selecting the EMERSON KJ4001X1-BE1 is part of designing a DeltaV S-series CHARM I/O system. Planning focuses on the required mix of signal types to select the appropriate CHARM cartridges (e.g., KJ3221X1-BA1 for AI).

Important Precautions:

• CHARM Cartridge Dependency: The KJ4001X1-BE1 base card is useless without the required number and type of CHARM cartridges. These must be specified separately.

• System Configuration: Each channel must be fully configured within the DeltaV engineering software to match the installed CHARM cartridge type and the field device.

• Power Budgeting: The total power consumption of all CHARMs on the card and the connected field devices must be within the limits of the associated power supply module in the cabinet.

• Hazardous Area Compliance: For use in intrinsically safe (IS) applications, the correct IS-rated CHARM cartridges and associated isolators must be used.
