Features:

  • Extends a compatible DeltaV carrier connection by 1.2 metres within the cabinet layout.
  • Uses the specified 44-pin connector arrangement for the carrier-to-carrier LocalBus path.
  • Forms the bottom extender assembly in the supported DeltaV carrier configuration.
The current ordering configuration is KJ4002X1-BF2, the DeltaV 1.2 m Bottom Extender Cable Assembly documented by Emerson for DeltaV M-Series Horizontal Carriers.

KJ4002X1-BF2 is used in Extending DeltaV horizontal-carrier LocalBus connections by 1.2 m. Its system role and configuration limits must remain aligned with the official specification.

Before commissioning KJ4002X1-BF2, verify the installed assembly, project wiring, power, software and environmental conditions that apply to this exact part number.

Availability is subject to Apter Power inventory and sourcing confirmation.

  • Extends DeltaV horizontal-carrier LocalBus wiring by 1.2 metres between compatible cabinet sections.
  • Supports layouts that separate I/O carriers while remaining within the specified bus-length limit.
  • Replaces an installed bottom extender when both cable length and connector arrangement match.
  • De-energize the system before disconnecting the extender cable.
  • Connect BF2 only at the bottom extender position defined by the carrier layout.
  • Secure the 1.2 m cable without exceeding its bend or routing space.
  • Keeps the cable assembly functional across its rated -40 to +70°C ambient range.
  • Maintains operation at 5 to 95 percent non-condensing relative humidity around the extender connections.
  • Routes through protective conduit wherever installation instructions require enclosure-to-enclosure cable protection.
  • Observe the hazardous-location conditions stated for the carrier extender assembly.
  • Use the referenced DeltaV Zone 2 installation documentation.
  • Verify the installed product label before applying approval markings.
Description
KJ4002X1-BF2 is the 1.2 m bottom extender cable assembly used between compatible DeltaV M-Series horizontal-carrier sections. The current carrier data sheet identifies the BF2 length as 1.2 m and the connection as 44 pin.

The cable carries LocalBus connectivity between carrier assemblies. Emerson limits the combined carrier and LocalBus-extender length and requires system power to be removed before disconnecting carrier or extender-cable hardware.

Confirm that the project requires the bottom, 1.2 m BF2 assembly rather than a top cable or a different length. Route and secure the cable according to the carrier layout and area classification.
