Product Description

Siemens filter modules act as a protective barrier between the power supply and the control components. Industrial environments are often filled with electromagnetic interference caused by high-frequency switching, motor drives, and heavy machinery. These modules utilize passive or active filtering circuits to attenuate unwanted high-frequency noise and voltage peaks. By cleaning the incoming power or filtering the outgoing signals, they prevent system malfunctions, data loss, and hardware degradation, ensuring a “clean” electrical environment for the entire automation cabinet.

Product Parameters

The technical characteristics of these modules are defined by their ability to handle specific electrical loads and frequency ranges:

• Rated Voltage: Available for various voltage levels, including standard 24V DC for control circuits and higher AC voltages for power lines.

• Rated Current: Scalable capacity to handle different load requirements, measured in Amperes.

• Attenuation Characteristics: Specific decibel (dB) ratings across a range of frequencies (usually kHz to MHz) to define noise reduction efficiency.

• Leakage Current: Low-leakage designs to ensure safety and compatibility with sensitive residual current devices (RCDs).

• Connection Technology: Features high-quality screw or push-in terminals for vibration-resistant wiring.

• Mounting Type: Standard DIN rail mounting for quick integration into industrial control cabinets.

Product Advantages

• System Reliability: Significantly reduces the risk of CPU resets or communication errors caused by electrical surges and noise.

• Regulatory Compliance: Helps the entire machine or installation meet mandatory EMC directives and CE certification requirements.

• Extended Component Lifespan: By absorbing voltage spikes and high-frequency harmonics, the modules reduce the thermal and electrical stress on downstream components.

• Space-Efficient Design: Compact footprints allow for high-density installation in crowded electrical cabinets.

• Maintenance-Free Operation: High-quality internal components ensure long-term durability without the need for periodic adjustments.

Important Considerations

• Correct Placement: For maximum effectiveness, filter modules should be installed as close as possible to the source of interference or the sensitive device being protected.

• Proper Grounding: The efficiency of a filter module is highly dependent on a low-impedance connection to the functional earth; improper grounding can render the filter ineffective.

• Current Derating: Users must consider the operating temperature, as high ambient heat may require derating the maximum allowable current.

• Wiring Separation: Input and output cables should be routed separately to prevent “cross-talk,” where noise bypasses the filter through inductive coupling.

Product Applications

• Power Supply Protection: Installed upstream of sensitive PLCs and HMIs to shield them from “dirty” industrial power grids.

• Motor Drive Integration: Used in conjunction with frequency converters to suppress the electromagnetic interference generated by high-speed switching.

• Sensitive Measurement Systems: Ensuring stable readings for high-precision analog sensors and weighing modules by removing line noise.

• Communication Line Stability: Protecting data hubs and network switches from transient overvoltages in long-distance cabling.

• Control Cabinet Entry Points: Serving as a central filter at the main power entry point of a machine to isolate the internal electronics from the external factory network.
