## Summary description

The Siemens SIRIUS ACT 3SU1401-1MC20-1CA1 is a professional-grade Profinet terminal module designed for industrial control systems. Featuring an integrated red LED indicator, this module is optimized for panel mounting applications. It ensures reliable signal transmission and status monitoring within the SIRIUS ACT series, providing a robust solution for automation and control panel configurations.

## Long description

The Siemens SIRIUS ACT Profinet terminal module is a professional-grade component designed for seamless integration into industrial control systems. This module serves as a command and LED interface, specifically engineered for panel mounting applications. It facilitates the connection of various actuating and signaling elements directly via the PROFINET communication protocol, ensuring efficient and reliable signal transmission within complex automation environments.
Advantages
This module features an innovative snap-on installation concept that allows for quick and secure mounting without the need for specialized tools. The design includes integrated twist prevention, which simplifies the assembly process on standard groove-free mounting holes. Built to withstand harsh industrial conditions, the unit offers a high degree of protection against dust, oils, and caustic substances, and it is even capable of enduring high-pressure jet cleaning. By utilizing PROFINET connectivity, users can significantly reduce wiring time and complexity while minimizing potential connection errors.
Suitable for
Industrial automation and control panel configurations
Applications requiring status monitoring via integrated red LED indicators
Systems utilizing PROFINET communication protocols
Environments where high-pressure cleaning or exposure to dust and oils is expected
When it may not be suitable
This module is specifically designed for use within the Siemens SIRIUS ACT ecosystem and may not be compatible with non-standard or third-party signaling devices that do not support the required mounting or communication interfaces. It is not intended for applications that do not utilize PROFINET for signal transmission.
Key specifications
Communication protocol: PROFINET
Integrated indicator: Red LED
Mounting type: Front plate / Panel mounting
Compatibility: SIRIUS ACT series
Installation method: Snap-on concept
How to use
The module is designed for simple, one-handed installation. Begin by preparing the mounting hole on the control panel, ensuring it is clean and free of debris. Align the module with the panel opening and utilize the snap-on mechanism to secure it firmly in place. Once mounted, connect the necessary actuating or signaling elements to the module. Finally, integrate the module into your existing PROFINET network architecture to enable communication and status monitoring.
What to consider before purchase
Ensure compatibility with your existing SIRIUS ACT control components
Verify that your control system supports PROFINET communication
Check the panel thickness and mounting hole requirements for the SIRIUS ACT series
Confirm that the red LED indicator meets your specific signaling requirements
Usage recommendations
For optimal performance and longevity, ensure that all connections are properly seated and that the module is installed in an environment that does not exceed its rated protection class. Regularly inspect the unit for signs of physical damage or debris accumulation, especially in environments subject to heavy industrial use.
