The KJ4001X1-HA1 12P0949X042 is a horizontal LocalBus cable extender designed specifically for the Emerson DeltaV scalable process control system. This module extends the LocalBus communication bus, allowing I/O carriers to be distributed across greater distances within the control system. The KJ4001X1-HA1 12P0949X042 provides LocalBus power at 12V DC with 8A capacity, ensuring reliable power distribution to connected I/O carriers. The KJ4001X1-HA1 12P0949X042 supports the 6.5-meter maximum total length requirement, making it essential for expanding DeltaV I/O installations in large-scale process control applications.

The KJ4001X1-HA1 12P0949X042 is certified for hazardous atmosphere use with Ex 3 G, Nemko No.02ATEX431U EEx nA IIC T4, making it suitable for Zone 2 installations in potentially explosive environments. The KJ4001X1-HA1 12P0949X042 operates over a wide temperature range of -40°C to 70°C and is rated IP20 for protection against solid objects. The KJ4001X1-HA1 12P0949X042 complies with ISA-S71.04-1985 Class G3 for airborne contaminants, ensuring reliable operation in harsh industrial environments.

The KJ4001X1-HA1 12P0949X042 can withstand shock of 10g half-sine wave for 11ms and vibration of 1mm peak-to-peak from 5 to 16Hz, and 0.5g from 16 to 150Hz. The KJ4001X1-HA1 12P0949X042 requires power to be de-energized before disconnecting any carriers or LocalBus extender cables, and cannot be removed or inserted with system power energized. The KJ4001X1-HA1 12P0949X042 contains no user-serviceable parts and should not be disassembled for any reason. Interconnecting cable between enclosures must be in conduit.

The KJ4001X1-HA1 12P0949X042 Emerson Horizontal LocalBus Cable may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

  • Petrochemical and Refining Control Centers: Linking heavy rows of I/O carrier bases managing hazardous zone sensors, flow transmitters, and safety interlocks.
  • Pharmaceutical and Bioreactor Facilities: Supporting horizontal layout additions of precise analog tracking modules for batch fermentation processing.
  • Large-scale Power Generation Plants: Extending the backplane of DeltaV nodes that monitor turbomachinery, thermal feedback, and continuous water-chemistry analysis.
  • Offshore Oil Platforms & Marine Operations: Deployed inside localized, space-restricted marshalling cabinets where I/O capacity must be expanded horizontally without changing the controller footprint.
  • High-Current Power Throughput: The physical conductor array inside the 37-pin cable layout supports an integrated LocalBus electrical delivery of up to 12 VDC at 8 Amps. This guarantees that downstream expanded I/O carriers receive stable, uncompromised system bus power.
  • Microsecond Backplane Latency: The cable exhibits low propagation delay, allowing the high-speed internal DeltaV parallel LocalBus communications to bridge across separate physical carrier rails seamlessly. It operates with zero measurable cycle-time degradation when properly deployed.
  • Shielded Signal Integrity: Wrapped in high-grade industrial electromagnetic interference (EMI) shielding, the 12P0949X042 design minimizes cross-talk and ensures that signal attenuation remains well within stringent industrial margins, maintaining continuous field bus communication.
  • DeltaV M-Series Hardware: Explicitly engineered to physically plug into and bridge DeltaV M-Series 8-pack and 4-pack I/O Carriers.
  • Form Factor Constraints: The assembly features custom Left-end and Right-end terminator plug-in boards that slide directly into the predefined terminal edge sockets of the native carriers.
  • Total Maximum Length Restriction: To prevent critical bus impedance mismatches, the cumulative length of all interconnected carriers and local bus extender cables within a single DeltaV controller node must not exceed a total of 6.5 meters (21.3 feet).
  • Hot-Swapping Prohibitions: While many DeltaV field modules support online removal, this cable assembly does NOT support hot-swapping or live disconnection. Unplugging the assembly while under power will instantly disconnect the 12V backplane, disrupting communications and risking electrical arcing that can damage downstream components.
