Allen-Bradley 2198-BARCON-55DC200

Within ALLEN BRADLEY's Servo lineup, the 2198-BARCON-55DC200 functions as a DC bus conditioner bar connector, purpose-built for the Kinetix 5700 servo drive family. This component bridges DC bus power across multiple drive modules within a shared DC bus configuration, allowing multiple axes to draw from a common power rail rather than requiring independent AC input for each drive. The ALLEN BRADLEY 2198-BARCON-55DC200 is rated for 200A continuous DC bus current at 55mm bus bar spacing, positioning it for high-axis-count machine architectures where centralized power distribution is preferred. Its primary role is physical and electrical interconnection — it is not a drive or amplifier itself, but rather a structural bus connector that enables multi-drive systems to share regenerative energy and balance load across axes. The part number encodes its key ratings: 55 refers to the bus bar pitch in millimeters, DC200 reflects the 200A current capacity. This makes it a critical sizing component when specifying or expanding a Kinetix 5700 system.

Integration-wise, the 2198-BARCON-55DC200 is designed exclusively for use within Allen-Bradley Kinetix 5700 multi-axis servo drive configurations, where it physically connects adjacent drive modules along a shared DC bus rail. Unlike single-axis Kinetix 5500 drives that operate on independent AC inputs, the Kinetix 5700 architecture relies on bus conditioner bar connectors like the 2198-BARCON-55DC200 to distribute DC bus voltage across an axis grouping, enabling energy recovery from decelerating axes to be consumed by accelerating ones. This architecture reduces net energy draw and AC line sizing requirements in high-throughput applications. The component operates alongside Kinetix 5700 dual-axis and single-axis inverter modules, coordinated through Studio 5000 Logix Designer software and EtherNet/IP communication back to CompactLogix or ControlLogix PLCs. Typical deployment environments include automotive body welding lines, multi-axis CNC machining centers, food and beverage packaging lines, and semiconductor wafer handling equipment — anywhere that tightly coordinated multi-axis motion is required.

Like other Servo units in heavy industrial duty, the 2198-BARCON-55DC200 operates in close proximity to significant thermal and electrical stress, as DC bus currents of up to 200A pass continuously through its bus bar connections. Common failure modes in this component class include contact oxidation at the bus bar mating surfaces, mechanical deformation of the connector housing from repeated thermal cycling, and micro-arcing damage at connection points caused by improper torque during installation or vibration over time. These failure modes can manifest as intermittent DC bus faults, unbalanced voltage distribution across the axis grouping, or outright loss of communication between drive modules. Facilities evaluating a 2198-BARCON-55DC200 replacement due to bus fault conditions should inspect mating surfaces on adjacent drive modules before installing a new unit. Operators looking to buy 2198-BARCON-55DC200 stock for sparing purposes, or sourcing a 2198-BARCON-55DC200 refurbished unit as a cost-controlled option, can find both through our industrial Servo repair services team. The ALLEN BRADLEY 2198-BARCON-55DC200 is available as new, refurbished, or as a repair exchange depending on availability and lead time requirements. Facilities can ship the 2198-BARCON-55DC200 to Flexa Systems for board-level repair, exchange for a refurbished unit, or order new stock — repairs are backed by a 2-year warranty from our Lewisville, TX shop.
