Product Description

Siemens Filter Modules are integrated or add-on components used to clean electrical signals and power lines. In industrial environments, devices like frequency converters and large motors generate significant electrical noise. These filter modules utilize inductive and capacitive circuits to attenuate this interference, ensuring that the system complies with Electromagnetic Compatibility (EMC) standards and preventing “crosstalk” between adjacent cables and modules.

Product Parameters

While technical specifications vary based on the voltage level and current rating, these modules are defined by several core parameters:

• Rated Voltage: Support for both single-phase and three-phase AC networks, as well as specific DC voltage ranges.

• Rated Current: Capacity to handle various load levels, typically measured in Amperes.

• Attenuation Frequency Range: The spectrum of noise frequencies (usually measured in kHz to MHz) that the module can effectively suppress.

• Leakage Current: The amount of capacitive current flowing to the protective earth, a critical factor for safety and RCD compatibility.

• Degree of Protection: Standard industrial ratings (such as IP20) ensuring protection against physical contact and dust.

• Power Loss: The amount of energy dissipated as heat during the filtering process.

Product Advantages

Implementing Siemens Filter Modules provides several technical and operational benefits:

• Enhanced System Stability: By removing electrical noise, these modules prevent erratic behavior in PLC logic and analog signal processing.

• EMC Compliance: They enable machinery to meet strict international standards for electromagnetic emissions and immunity.

• Extended Equipment Lifespan: Protecting downstream components from high-frequency voltage stress reduces thermal wear and premature hardware failure.

• Compact Integration: Many modules are designed to match the form factor of the controllers, allowing for seamless DIN-rail mounting and space-saving cabinet layouts.

• Reduced Downtime: Eliminating “phantom” faults caused by interference leads to higher production reliability and easier troubleshooting.

Important Considerations

To ensure the effectiveness of a filter module, the following guidelines should be observed:

• Proper Grounding: The module must have a low-impedance connection to the functional earth; without a solid ground, the filter cannot divert interference effectively.

• Cable Routing: Input (dirty) and output (clean) lines should be kept physically separate to prevent noise from jumping back onto the filtered lines.

• Heat Dissipation: Ensure adequate ventilation within the control cabinet, as filters generate heat during operation.

• Saturation Limits: Avoid exceeding the rated current, as excessive loads can saturate the internal inductors, rendering the filter ineffective.

• Compatibility: Verify that the filter type matches the specific switching frequency of the connected drive or power supply.

Product Applications

Siemens Filter Modules are essential in environments where precision and power quality are paramount:

• Motor Drive Systems: Suppressing high-frequency harmonics generated by pulse-width modulation (PWM) in variable speed drives.

• Sensitive Measurement Areas: Protecting high-precision analog sensors and weighing systems from power line noise.

• Sensitive Control Cabinets: Ensuring the “clean” power supply of PLCs, HMIs, and communication gateways in noisy factory environments.

• Renewable Energy: Filtering power outputs in solar or wind applications before they interface with the grid or local control systems.

• Medical and Laboratory Automation: Maintaining extreme signal integrity for automated testing and diagnostic equipment.
