Product Overview

The Emerson KJ4001X1-BE1 (Order Number 12P0818X072) is a foundational hardware component of the DeltaV™ M-series I/O Subsystem. This 8-wide I/O carrier provides the physical and electrical backplane required to mount and interconnect up to eight DeltaV I/O interface cards and their corresponding terminal blocks. It facilitates the distribution of local bus power and signals between the I/O modules and the system controller.

This specific revision features an integrated shield designed to provide superior electromagnetic compatibility (EMC). The shielded architecture is critical for protecting low-level analog and digital signals from the high-frequency interference commonly found in heavy industrial environments. While this product line was officially moved to a discontinued status in December 2018, it remains a vital requirement for the maintenance, repair, and expansion of established DeltaV Distributed Control System (DCS) nodes.

Technical Characteristics and Architecture

• High-Density Backplane: Accommodates up to eight standard I/O modules, allowing for efficient use of cabinet space and simplified system scaling.

• Enhanced Signal Shielding: Features a robust metallic shield that significantly reduces the impact of RFI and EMI, ensuring high-fidelity data transmission across the local bus.

• Plug-and-Play Integration: Supports the modular "Removal and Insertion Under Power" (RIUP) capability of DeltaV modules, enabling maintenance without de-energizing the entire I/O rack.

• Passive Reliability: As a passive backplane component, the carrier is engineered for extreme longevity with no active electronic components that are prone to frequent failure.

• Rugged Mounting Design: Built to withstand the mechanical stresses of industrial plant environments, including vibration and thermal expansion within control enclosures.

• Integrated Power Distribution: Efficiently routes internal redundant power to all eight slots, ensuring continuous operation of field-facing interface cards.
