6KA9902/EL1/621
- Processing Speed: Although specific processing speed data is not provided, as an industrial control module, it is designed to process input signals and generate control outputs in a timely manner. It can quickly respond to changes in the industrial process, ensuring real – time control. In a fast – paced manufacturing process, it can rapidly adjust the operation of machinery based on sensor feedback.
- Communication Speed: With the Profinet communication protocol, it can achieve relatively high – speed data transfer. Profinet is known for its fast and reliable communication capabilities, allowing for quick exchange of data between the module and other devices in the industrial network. This enables real – time monitoring and control, reducing the latency in the control loop.
3.3 Environmental Parameters
- Operating Temperature Range: The module is designed to operate within a temperature range of – 25 °C to + 60 °C. This wide temperature tolerance makes it suitable for use in various industrial environments, from cold storage facilities where products need to be stored at low temperatures to hot manufacturing workshops where machinery generates heat.
- Relative Humidity: It can withstand a relative humidity range of 5% to 95%. This humidity tolerance allows it to be used in humid industrial areas, such as food processing plants where there is often high humidity due to the nature of the production process, or in coastal – area industrial facilities where the air contains more moisture.
4. Product Specifications

- Physical Dimensions: The Siemens 6KA9902/EL1/621 has dimensions of 120 mm x 75mm x 35mm. Its compact size makes it convenient for installation in standard industrial control cabinets or within machinery with limited space.
- Weight: It weighs 0.3 kg. This lightweight design is beneficial for installation and maintenance, as it reduces the physical effort required by technicians. It also has minimal impact on the overall weight and balance of the equipment in which it is installed.
- Protection Level: As mentioned earlier, it has a protection level of IP54. This provides protection against dust ingress and water splashing from any direction. In industrial environments where dust and water can pose a threat to the normal operation of electronic components, the IP54 protection level helps to ensure the module’s reliability and longevity.
- Installation Method: While not explicitly stated in the given sources, common installation methods for industrial modules like this include DIN – rail mounting. DIN – rail mounting is a popular choice in industrial applications as it allows for quick and secure installation of components in control cabinets. This method enables easy replacement or addition of modules during system upgrades or maintenance.
