Emerson DeltaV LocalBus Extension Interface
The KJ4001X1-HB1 extends the DeltaV M-Series LocalBus connection on the right side of an I/O carrier arrangement. It provides the physical interface required for LocalBus extender cable connections and maintains LocalBus power distribution at 12 VDC with an 8 A capacity.
The module supports hazardous area installations with Ex ec IIC Gc certification. Therefore, installation procedures must follow the DeltaV Zone 2 installation requirements and approved hardware configuration guidelines.
Frequently Asked Questions
Q: Can the KJ4001X1-HB1 be removed or inserted while system power remains active?
A: No. The unit cannot be removed or inserted with energized system power. The power supply must be de-energized before disconnecting carriers or LocalBus extender cables.
Q: What is the maximum permitted length for the connected I/O carrier and LocalBus extender arrangement?
A: The combined length of I/O carriers and LocalBus Extenders must not exceed 6.5 meters.
Q: Does the KJ4001X1-HB1 require field calibration after installation?
A: No. The unit contains no calibration adjustment functions and does not require calibration.
Field Installation Guidelines
Install the KJ4001X1-HB1 according to DeltaV M-Series hardware installation procedures and hazardous area requirements.
Before installation or removal, isolate system power and verify that all LocalBus connections are de-energized. Route interconnecting cables between separate enclosures inside conduit as specified by the installation documentation.
Maintain approved LocalBus extender cable routing practices and avoid unauthorized modifications to the module housing. The unit contains no user-serviceable components; therefore, do not disassemble the module during field maintenance activities.
