Product Details

2198-DB42-F Product Description

The Allen-Bradley 2198-DB42-F is a dedicated EMC line filter engineered for Kinetix servo drive systems operating in high-demand industrial environments. Designed to suppress electromagnetic interference at the power input stage, this filter plays a critical role in energy-efficient motion control architectures — reducing conducted emissions, stabilizing drive input power quality, and protecting downstream automation components from noise-induced faults. With a rated current capacity suited for mid-to-large servo axis configurations, the 2198-DB42-F integrates seamlessly into Allen-Bradley's Kinetix 5500 and Kinetix 5700 servo drive families, enabling compliant, low-emission operation across smart manufacturing and process automation lines.

In modern production environments where energy visibility and load management are paramount, the 2198-DB42-F contributes directly to system-level efficiency. By attenuating high-frequency switching noise generated by PWM-controlled servo drives, it reduces reactive power disturbances on the supply bus, lowers thermal stress on upstream power distribution equipment, and minimizes the risk of nuisance tripping in sensitive control circuits. This translates to measurable reductions in energy waste, lower heat dissipation across the panel, and more stable operation of co-located automation assets.

The 2198-DB42-F is purpose-built to work within Allen-Bradley's integrated motion and energy control ecosystem. In a typical Kinetix 5700 multi-axis servo system, the filter is installed at the AC input of the shared DC bus module, ensuring that all downstream servo drives — including the 2198-S086-ERS3 and 2198-S160-ERS3 axis modules — operate with clean, filtered power. This directly reduces the switching noise that would otherwise propagate back into the facility power grid and affect co-located equipment.

Within a broader automation architecture, the 2198-DB42-F works in concert with the Allen-Bradley CompactLogix or ControlLogix PLC platforms, which coordinate motion profiles and energy demand scheduling across production cells. The PLC's motion task execution — managing acceleration ramps, deceleration regeneration, and torque limits — is made more predictable when the servo drive input is protected from EMI-induced voltage fluctuations. Paired with a PowerFlex 755 variable frequency drive on auxiliary motor axes, the filter helps maintain a stable common power bus, preventing cross-interference between servo and VFD switching frequencies.

Power monitoring is handled upstream by devices such as the Allen-Bradley PowerMonitor 5000, which tracks real-time energy consumption, power factor, and harmonic distortion across the production line. The 2198-DB42-F's EMI suppression capability directly improves the accuracy of these measurements by reducing noise artifacts on the current and voltage waveforms. This data feeds into the FactoryTalk Energy Manager or a SCADA system via EtherNet/IP, enabling energy managers to correlate drive-level efficiency with line-level consumption trends.

On the I/O and communications side, the filter supports stable operation of 1734 POINT I/O modules and 1756 ControlLogix I/O racks that share the same electrical panel. High-frequency EMI from unfiltered servo drives is a known cause of I/O communication errors and spurious fault signals — the 2198-DB42-F eliminates this risk. HMI terminals such as the PanelView Plus 7 also benefit from reduced electrical noise, maintaining reliable touchscreen responsiveness and display integrity in high-cycle production environments.

In smart factory deployments, energy optimization is not limited to selecting efficient motors or drives — it extends to every component in the power chain. The Allen-Bradley 2198-DB42-F addresses a frequently overlooked source of energy waste: electromagnetic interference that forces drives to operate with degraded efficiency, increases thermal output, and shortens component service life.

By installing the 2198-DB42-F at the servo drive input, production engineers achieve several measurable outcomes. First, the filter stabilizes the input voltage waveform seen by the Kinetix drive's rectifier stage, reducing the harmonic content that contributes to excess heat generation in the drive's power module. Lower thermal load means the drive's cooling system operates less aggressively, reducing fan energy consumption and extending bearing life. Second, the suppression of conducted emissions prevents interference with proximity sensors, encoder feedback lines, and resolver signals — all of which are critical to maintaining precise motion control and consistent production cycle times.

In regenerative braking scenarios — common in high-inertia servo applications such as press feeders, winding machines, and robotic transfer units — the 2198-DB42-F ensures that regenerated energy returned to the DC bus is not contaminated with switching artifacts that could destabilize the bus voltage. This supports more effective use of the Kinetix 5700's shared DC bus regeneration capability, reducing the need for braking resistors and the associated energy dissipation as heat.

From a predictive maintenance perspective, consistent EMI suppression provided by the 2198-DB42-F reduces the rate of insulation degradation in motor windings and cable assemblies. This extends mean time between failures (MTBF) for the entire servo axis, reducing unplanned downtime and the energy costs associated with emergency maintenance and production restarts. Combined with FactoryTalk Diagnostics or a connected SCADA platform, maintenance teams can monitor drive health trends and schedule interventions during planned downtime windows — keeping production lines running at optimal throughput and energy efficiency.

Q1: What energy efficiency benefit does the 2198-DB42-F provide in a Kinetix servo system? The 2198-DB42-F suppresses conducted EMI at the servo drive input, reducing reactive power disturbances on the supply bus, lowering thermal stress on the drive's power module, and improving the accuracy of upstream power monitoring. The net result is a more energy-efficient servo axis with reduced heat dissipation and longer component service life.

Q2: Is the 2198-DB42-F compatible with both Kinetix 5500 and Kinetix 5700 drive systems? Yes. The 2198-DB42-F is designed for use with Allen-Bradley Kinetix 2198-series infrastructure, supporting both the Kinetix 5500 single-axis and Kinetix 5700 multi-axis shared DC bus configurations. Always verify the rated current (42 A) matches your axis power requirements before installation.

Q3: Can this filter replace other EMC filters in the 2198 series, and what is the testing process before shipment? The 2198-DB42-F is specific to its rated current class within the Kinetix 2198 filter family. Substitution with other 2198-series filters (e.g., 2198-DB20-F or 2198-DB63-F) should only be made after confirming current rating compatibility with your drive configuration. All units supplied by NANKMOS undergo pre-shipment functional verification to confirm electrical integrity and compliance with original manufacturer specifications.

Q4: What is the warranty coverage and stock availability for the 2198-DB42-F? NANKMOS provides a 12-Month Warranty on the Allen-Bradley 2198-DB42-F, covering defects in materials and workmanship under normal operating conditions.
