1336-BDB-SP68D Allen-Bradley Filter Modules

Product  Description：

Allen-Bradley Filter Modules, produced by Rockwell Automation, are specialized electrical power conditioning and signal protection components designed to safeguard programmable automation controllers (PACs), programmable logic controllers (PLCs), variable frequency drives (VFDs), and sensitive instrumentation from electrical disturbances. These modules—including EMC/RFI line noise filters, power supply output filter modules, and inline suppression accessories—attenuate electromagnetic interference (EMI), radio frequency interference (RFI), transient voltage surges, and line harmonics.

By filtering unwanted high-frequency electrical noise generated by switching power supplies, fast semiconductor switching, heavy inductive switching, and motor drives, Allen-Bradley filter modules maintain clean power distribution and high signal integrity across control cabinets. They prevent logic resets, communication disruptions, sensor inaccuracies, and premature electronic component degradation in demanding industrial manufacturing environments.

Product Parameters

• Module Categories: AC Line Filters, EMC/RFI Noise Suppression Modules, DC Power Supply Output/Redundancy Filter Modules, and Drive Line Reactors/Filters.

• Operating Voltage Range: 100V AC to 480V AC for AC power line filters; 12V DC to 48V DC for DC control circuit filter modules.

• Rated Current Capacity: 1A to 30A for DIN-rail control cabinet filters, with higher current ratings available for motor drive line filters.

• Operating Line Frequency: 50 Hz to 60 Hz nominal power frequency.

• Interference Attenuation Frequency: Targeted high-frequency noise suppression from 150 kHz to 30 MHz (EMI/RFI band).

• Insertion Loss Rating: Up to 40 dB to 60 dB noise attenuation across target frequency bands.

• Mounting Style: 35 mm DIN-rail mounting or direct panel chassis mounting.

• Enclosure Protection Class: IP20 finger-safe housing for standard cabinet installation.

• Operating Temperature Range: -25°C to +70°C with standard thermal derating at elevated temperatures.

• Safety and Regulatory Compliance: UL Listed, CE Marked, CSA Certified, RoHS Compliant, and compliant with EN/IEC 61000 EMC standards.

Product Advantages

• Superior Noise Suppression: Effectively eliminates high-frequency noise, transient voltage spikes, and electromagnetic interference on power and signal lines.

• Enhanced System Uptime: Prevents unexplainable PLC CPU resets, fieldbus communication packet errors, and false sensor triggering caused by line disturbances.

• Regulatory EMC Compliance: Enables industrial control panels and OEM machinery to meet stringent international electromagnetic compatibility standards and CE directives.

• Seamless Panel Integration: Compact DIN-rail form factors allow quick installation alongside Allen-Bradley power supplies, circuit breakers, and controller racks.

• Prolonged Equipment Lifespan: Shields sensitive microelectronics, power supplies, and analog field instruments from damaging voltage transients and continuous electrical stress.

Important Precautions

• Grounding Integrity: Connect the filter module earth terminal directly to a low-impedance master ground bus bar using the shortest possible wire length, as filter efficiency relies heavily on a solid ground connection.

• Physical Wire Separation: Keep incoming unfiltered power wiring strictly separated from clean filtered output wiring to prevent noise from coupling back into filtered circuits.

• Observe Current Derating: Ensure the continuous load current does not exceed the module rated current rating, taking into account ambient control cabinet operating temperatures.

• High-Voltage Dielectric Testing: Disconnect or bypass filter modules during panel dielectric (Hi-Pot) insulation testing to avoid damaging internal filter capacitors or causing false leakage current trips.

• Airflow and Clearance: Maintain recommended clearance distances above and below the module during cabinet installation to ensure adequate thermal convection cooling.

Product Applications

• Variable Frequency Drive and Servo Systems: Suppressing electromagnetic interference generated by VFDs and servo drives to prevent line pollution back to the facility grid.

• PLC and PAC Control Cabinets: Cleaning input power feeds supplying ControlLogix, CompactLogix, and Micro800 system power supplies and expansion racks.

• Sensitive Analog and Sensor Instrumentation: Conditioning DC bus voltage supplying high-accuracy flow meters, pressure transmitters, and analytical sensors.

• Industrial OEM Machinery: Providing mandatory line-side noise filtering for export machinery requiring international electrical safety compliance.

• Packaging and Assembly Lines: Protecting automated sorting, robotic, and motion control systems operating in proximity to heavy switching inductive loads.
