DeltaV LocalBus Extension and Signal Interface
The Emerson KJ4010X1-BG1 operates as a LocalBus right extender for DeltaV I/O carrier configurations. It transfers LocalBus communication and power signals through dedicated extender cable assemblies. Therefore, the module supports distributed carrier arrangements while maintaining the electrical connection path required by DeltaV hardware architecture.
The module uses a 12.6 VDC LocalBus power interface with an 8 A supply capability. In addition, the unit supports hazardous area installation requirements under ATEX Zone 2 conditions with EEx nA IIC T4 classification.
For Emerson DeltaV systems, the LocalBus architecture requires controlled cable routing and defined connection distances. The extender assembly must be installed according to DeltaV Zone 2 installation documentation to maintain the specified environmental and electrical limits.
Frequently Asked Questions
Q: Can the KJ4010X1-BG1 be removed while system power remains active?
A: No. The unit cannot be removed or inserted with energized system power. Power must be de-energized before disconnecting carriers or LocalBus extender cables.
Q: Does the KJ4010X1-BG1 require calibration after installation?
A: No. The module does not require calibration and contains no user-serviceable adjustment components.
Q: What cable length limitation applies to the LocalBus extender configuration?
A: The combined length of I/O carriers and LocalBus Extender cables must not exceed 6.5 m. Interconnecting cables between enclosures must be installed inside conduit.
Field Installation Guidelines
- Install the KJ4010X1-BG1 according to Emerson DeltaV Zone 2 installation instructions and hazardous area requirements.
- Verify that system power is removed before connecting or disconnecting LocalBus extender cables.
- Route LocalBus cables separately from high-voltage power wiring to reduce electrical interference.
- Maintain proper cable shielding and grounding practices according to site electrical standards.
- Confirm enclosure wiring paths when cables pass between separate cabinets, and install interconnecting cables inside conduit.
- Do not disassemble the module because it contains no user-serviceable components.
- Check the product label for serial number, manufacturing location, and production date before field deployment.
