Product Description

Siemens Filter Modules are engineered to suppress electromagnetic interference (EMI) and radio frequency interference (RFI) that can propagate through power lines or signal paths. In an industrial environment, large motors, frequency converters, and contactors create significant electrical “noise” that can cause malfunctions in PLC processors or errors in analog signal readings. Filter modules are installed to clean the incoming power supply or to stabilize the internal backplane bus. They are typically compact, rail-mounted units that integrate seamlessly with the rest of the control hardware, ensuring that the entire system operates within the required regulatory limits for electromagnetic emissions and immunity.

Product Parameters

The performance of a filter module is defined by its ability to attenuate unwanted frequencies while maintaining the flow of clean power:

• Rated Voltage: Compatibility with standard industrial power ranges, typically for 24V DC systems or 120V/230V AC lines.

• Rated Current: The maximum continuous current the module can handle without overheating.

• Attenuation Characteristics: The specific decibel (dB) reduction of noise across various frequency ranges (e.g., from 150 kHz to 30 MHz).

• Leakage Current: The amount of current that flows to the ground through the filter components, which is a critical safety parameter.

• Capacitance and Inductance Values: Internal electrical properties that determine the effectiveness of the filtering circuit.

• Operating Temperature: The range in which the module maintains its filtering efficiency and thermal stability.

Product Advantages

• Increased System Reliability: By removing electrical spikes and high-frequency noise, these modules prevent unexpected CPU stops and data corruption.

• Improved Signal Accuracy: Essential for analog applications, as they prevent “jitter” and fluctuations in sensitive measurement loops.

• Compliance with Standards: Helps the overall control cabinet meet strict international EMC directives and CE requirements.

• Extended Hardware Lifespan: Protects the internal capacitors and power stages of PLCs and I/O modules from the cumulative stress of electrical surges.

• Space-Saving Integration: Designed in the same form factor as standard PLC components, allowing for a uniform and organized cabinet layout.

Precautions for Use

• Correct Mounting: For maximum effectiveness, filter modules must be mounted with a low-impedance connection to the ground rail; paint or corrosion on the mounting surface can degrade performance.

• Wiring Separation: Input (dirty) and output (clean) cables should be routed separately. Crossing these cables can lead to “noise coupling,” where interference bypasses the filter through induction.

• Proper Sizing: Ensure the total current load of all downstream modules does not exceed the rated current of the filter module to avoid voltage drops or thermal failure.

• Orientation: Follow the manufacturer’s guidelines regarding mounting orientation to ensure proper heat dissipation.

• Grounding Connection: Use the shortest possible grounding straps with a large cross-sectional area to ensure that high-frequency interference is effectively diverted to the earth.

Product Applications

Siemens Filter Modules are utilized in environments where electrical cleanliness is a priority:

• Sensitive Measurement Areas: Protecting systems that handle high-resolution analog signals from sensors and transmitters in laboratory or precision manufacturing settings.

• High-Interference Environments: Used in cabinets that house variable frequency drives (VFDs) or large motor starters which generate significant switching noise.

• Telecommunications and Data Hubs: Ensuring clean power for communication modules that manage critical data links between remote sites.

• Power Quality Improvement: Serving as a localized stabilizer for PLC stations located at the end of long power distribution runs in large factories.

• Compliance Testing: Integrated into systems during the design phase to ensure the final product passes mandatory electromagnetic compatibility testing for global export.
