Product Details
The Emerson KJ4001X1-NB1, also cataloged as the KJ4001X1 1-Wide I/O Carrier Extender, operates as a dedicated hardware component for local bus expansion and power routing across hazardous area I/O carrier assemblies within Emerson DeltaV systems. It extends internal system backplane signals while managing dual DC power distribution to adjacent expansion slots.

4-20 mA HART Loop Protocol and Channel Isolation
The KJ4001X1-NB1 carrier extender isolates power distribution paths between the 12 VDC system local bus and the 30 VDC bussed field supply. Integrated isolation barriers prevent field power transients from propagating into the backplane logic. This design ensures uncorrupted signal passthrough for multi-channel analog cards communicating via the 4-20 mA HART loop protocol across adjacent carrier slots.
Frequently Asked Questions
Q: What are the dual DC power supply distribution limits for the KJ4001X1-NB1 extender?
A: The carrier extender routes 12 VDC at up to 8 A for local bus logic power and 30 VDC at up to 6.5 A for bussed field power.
Q: Is the KJ4001X1-NB1 carrier extender rated for harsh airborne environments?
A: Yes, the unit complies with ISA-S71.04 Class G3 standards for airborne contaminants and operates within a temperature range of -40 to +70 deg C.
Q: How does the extender mount within an existing DeltaV carrier setup?
A: The module snaps directly onto the standard DeltaV 1-wide DIN rail carrier slot, extending backplane logic and power connections to secondary carriers.
Field Installation Guidelines
- Isolate all 12 VDC local bus and 30 VDC bussed field power sources before attaching the extender module to the carrier assembly.
- Align the rear connector pins of the KJ4001X1-NB1 with the primary DeltaV carrier slot interface and press firmly into place.
- Verify that the DIN rail grounding latch engages fully to ensure proper chassis earth bonding and surge suppression.
- Route field wiring away from the bus extender logic interfaces to reduce electromagnetic interference.
- Confirm that total combined current draw on adjacent expanded slots does not exceed 8 A on the 12 VDC bus or 6.5 A on the 30 VDC field bus.
