Product Description

Siemens Filter Modules are passive or active electronic units used to suppress electromagnetic interference (EMI) and radio frequency interference (RFI). These modules are typically installed between the power supply and the control components or integrated into signal lines to clean the incoming electrical environment. By filtering out voltage spikes, harmonics, and transient noise, they ensure that input/output modules and CPUs receive stable power and clean data signals, preventing erratic system behavior or hardware failure.

Product Parameters

The technical specifications of filter modules are defined by their ability to attenuate unwanted electrical noise:

• Rated Voltage: Support for standard industrial ranges, typically 24V DC for logic circuits or 120V/230V AC for primary power lines.

• Rated Current: Capacity to handle specific current loads without overheating, often ranging from a few amperes to high-capacity industrial ratings.

• Attenuation Range: Specified frequency bands where the module effectively reduces noise, usually measured in decibels (dB).

• Leakage Current: Technical limits on the current that flows to the protective earth (ground) during operation.

• Mounting Type: Standardized DIN rail mounting compatible with other automation components in the control cabinet.

Product Advantages

• Enhanced System Stability: Significantly reduces the risk of “ghost signals” or CPU resets caused by external electrical interference.

• Component Longevity: Protects sensitive internal electronics from the cumulative wear of high-frequency transients and voltage fluctuations.

• EMC Compliance: Helps the entire control cabinet meet strict international standards for electromagnetic emissions and immunity.

• Compact Integration: Designed to match the form factor of the PLC or power supply series, ensuring a uniform and space-efficient cabinet layout.

• Passive Reliability: Most filter units are built with high-quality passive components that require no software configuration and have a very long service life.

Precautions

• Grounding Quality: The effectiveness of a filter module is highly dependent on a low-impedance connection to a functional earth; poor grounding can render the filter useless.

• Installation Proximity: For maximum effectiveness, the module should be installed as close as possible to the source of interference or the sensitive device being protected.

• Current Derating: Users must check the thermal limits and derating curves if the module is operated in high-temperature environments or at high altitudes.

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

Product Applications

Siemens Filter Modules are essential in environments with high electrical noise or where precision is critical:

• Heavy Industrial Environments: Protecting control systems in plants with large motors, frequency converters, or welding equipment that generate significant EMI.

• Highly Sensitive Instrumentation: Ensuring clean power for analog-to-digital converters and precision measurement modules in laboratory or process settings.

• Unstable Power Grids: Acting as a buffer in regions where the electrical supply is prone to surges, harmonics, or switching transients.

• Communication Networks: Shielding the power lines of interface modules to prevent noise from corrupting high-speed data transmission across the backplane.
