Product Description

Siemens Filter Modules act as a barrier against electrical disturbances that originate from the power grid or from high-frequency switching devices like variable frequency drives. These modules clean the incoming or outgoing electrical signals by filtering out high-frequency noise and voltage peaks. By maintaining a “clean” electrical environment, they prevent data corruption in communication lines and ensure the stable operation of the PLC and its associated I/O modules in harsh industrial settings.

Product Parameters

• Rated Voltage: Designed to operate within standard industrial voltage ranges, such as 24V DC or various AC line voltages.

• Rated Current: Capacity to handle specific load currents without overheating or significant voltage drops.

• Attenuation Characteristics: Specific decibel (dB) ratings for noise reduction across a wide frequency spectrum (typically from kHz to MHz).

• Insertion Loss: Minimal loss of the primary signal or power while maximizing the suppression of unwanted frequencies.

• Mounting Type: Generally designed for DIN rail mounting to match the form factor of other PLC and power supply components.

Product Advantages

• Improved System Reliability: Significantly reduces the risk of random system resets, data errors, and hardware damage caused by electrical transients.

• Compliance with Standards: Helps the entire control cabinet meet strict electromagnetic compatibility (EMC) regulations and CE requirements.

• Hardware Longevity: By smoothing out voltage spikes, the module protects the internal circuitry of sensitive electronic components, extending their operational lifespan.

• Compact Design: Engineered to take up minimal space on the mounting rail while providing robust protection for the entire system.

• Passive Operation: Most filter modules do not require complex programming or external control, providing “set and forget” protection.

Safety and Operational Precautions

• Correct Grounding: The effectiveness of a filter module is highly dependent on a low-impedance connection to the functional earth; ensure the mounting rail or grounding terminal is properly bonded.

• Input/Output Separation: To prevent “noise coupling,” keep the unfiltered input wires physically separated from the filtered output wires within the cabinet.

• Current Rating: Never exceed the rated current of the filter, as saturation can occur, making the filter ineffective and potentially causing it to overheat.

• Leakage Currents: Be aware that some high-performance filters can produce small leakage currents to the ground; ensure this is compatible with the system’s residual current monitoring.

• Placement: For maximum effectiveness, the filter should be installed as close as possible to the source of the interference or the entry point of the power supply.

Product Applications

• VFD Integration: Suppressing high-frequency noise generated by motor drives to protect nearby analog signals and communication modules.

• Sensitive Measurement: Ensuring clean power for high-resolution analog-to-digital converters and precision sensors in laboratory or process environments.

• Unstable Power Grids: Protecting automation equipment in facilities where the main power supply is subject to heavy switching noise from large machinery.

• Telecommunications: Filtering DC power lines for communication gateways and industrial routers to maintain high data throughput without interference.
