Overview
Configured for expander bus connection in the Bailey Infi 90 system, the ABB NKEB01 (NKEB01 Expander Bus Interconnect Cable) provides direct physical interconnection between MMUs. The cable carries bus connections across the specified expander interface and uses 24-26 AWG conductors with a 300 V AC voltage rating and a current rating of 1 A per conductor.

ABB Industrial Bus Interconnection Characteristics
The ABB NKEB01 provides a physical cable connection for the expander bus between compatible MMUs in the Bailey Infi 90 architecture. Correct cable routing supports orderly bus interconnection and reduces unnecessary mechanical stress on the connectors.
As a passive interconnect component, the NKEB01 does not perform independent signal processing or firmware execution. Therefore, bus communication behavior depends on the connected MMUs, associated control hardware, connector condition, and installation integrity.
The specified conductor gauge and cable length define the physical characteristics of the interconnection. During installation, maintain the intended routing path and avoid unnecessary cable extension or modification.
Frequently Asked Questions
Q: What is the primary function of the ABB NKEB01?
A: The NKEB01 connects the Expander Bus between MMUs within the Bailey Infi 90 system.
Q: Does the NKEB01 require an independent power supply?
A: No independent power consumption or external power requirement is specified for this passive interconnect cable.
Q: Can the NKEB01 cable length be changed during installation?
A: The specified cable length is 1 foot (0.30 meters). Cable modification or extension should not be assumed without verifying the electrical and system requirements of the connected equipment.
Field Installation Guidelines
Inspect the cable, insulation, and connectors before installation. Do not install the cable if the conductor insulation or connector assembly shows visible mechanical damage.
Route the NKEB01 separately from high-current power wiring where practical. This installation practice helps reduce exposure to electrical interference and prevents unnecessary mechanical loading.
Connect the cable only after confirming the correct Expander Bus interfaces on the MMUs. Ensure that each connector is fully seated and that the cable is not twisted, sharply bent, or placed under continuous tension.
Maintain appropriate cable support inside the control cabinet. In addition, avoid routing the cable across sharp edges or areas where repeated movement may damage the conductor assembly.
