Product Description

Siemens filter modules are engineered to clean and stabilize the power supply or signal lines within a PLC rack or a distributed I/O station. In industrial environments, large motors, frequency converters, and switching power supplies often generate significant electromagnetic interference (EMI). These modules utilize inductive and capacitive filtering circuits to dampen voltage spikes, harmonics, and electrical noise. By providing a “clean” electrical environment, they protect sensitive electronic components from premature aging and prevent logic errors caused by transient interference.

Product Parameters

The technical performance of a filter module is defined by its ability to attenuate noise across a specific spectrum:

• Rated Voltage/Current: The maximum continuous operating levels for power line filtering.

• Attenuation Characteristics: Specified in decibels (dB), indicating the module’s effectiveness at reducing noise at various frequencies.

• Leakage Current: The amount of current that flows to the ground through the filter, which is critical for safety and RCD compatibility.

• Frequency Range: The spectrum of electromagnetic interference (EMI) that the module is designed to suppress.

• Capacitance and Inductance Values: Internal electrical properties that define the filtering strength.

• Operating Temperature: The thermal range within which the module can maintain its filtering efficiency.

Product Advantages

• Enhanced System Reliability: Dramatically reduces the risk of intermittent software glitches and hardware resets caused by electrical noise.

• Signal Integrity: Ensures that analog measurement values remain stable and accurate by eliminating high-frequency fluctuations.

• Extended Hardware Lifespan: Protects internal semiconductor components from the stress of voltage transients and spikes.

• EMC Compliance: Helps the entire control cabinet meet stringent international electromagnetic compatibility standards and regulations.

• Space-Efficient Design: Compact form factors allow for easy integration into standard PLC rails without requiring extensive cabinet redesign.

Usage Precautions

• Correct Placement: Filters should be installed as close as possible to the source of interference or the sensitive component being protected.

• Grounding Connection: High-performance filtering relies on a low-impedance connection to the functional earth; ensure the mounting rail or grounding terminal is properly bonded.

• Current Derating: Be mindful of the module’s thermal limits; if operating in high-ambient temperatures, the maximum allowable current may be reduced.

• Wiring Separation: Keep the “dirty” input wires and the “clean” output wires physically separated to prevent noise from jumping across cables via induction.

• Series vs. Parallel: Ensure the module is wired according to the manufacturer’s specifications, as power filters and signal filters have different installation requirements.

Product Applications

Filter modules are essential in environments with high levels of electrical “pollution”:

• Heavy Industrial Plants: Used in facilities with large inductive loads, such as arc furnaces, heavy-duty cranes, or welding stations.

• Precision Measurement: Integrated into systems where high-resolution analog sensors are sensitive to micro-volt fluctuations.

• Distributed I/O Stations: Protecting remote racks that are located far from the main power source and are susceptible to line noise.

• Variable Speed Drive Systems: Placed near frequency converters to suppress the harmonics generated by high-speed switching transistors.
