## Summary description

The Siemens SIRIUS ACT 3SU1400-1LK10-3AA1 is a standard PROFINET interface module designed for industrial automation systems. It operates on 24V DC and features reliable spring-type terminals for secure connections. This module is engineered for panel mounting and facilitates efficient communication within the SIRIUS ACT command and signaling device range, ensuring robust performance in demanding industrial environments.

## Long description

The Siemens SIRIUS ACT PROFINET standard interface module is a high-performance component designed to integrate command and signaling devices into industrial automation networks. Operating at 24V DC, this module serves as a critical link between physical control elements and the PROFINET communication protocol, enabling efficient data exchange and streamlined control system architecture.
Advantages
This interface module offers significant benefits for industrial control panel design by simplifying the connection of multiple actuating and signaling elements. The integration of PROFINET technology allows for reduced wiring complexity and minimized installation time compared to traditional hard-wired systems. Its robust construction ensures reliable operation in demanding environments, while the spring-type terminal design provides secure, vibration-resistant connections that maintain signal integrity over time. The module is engineered for easy front-plate mounting, supporting a flexible configuration that can accommodate up to 20 terminal modules, making it a versatile solution for complex control panels.
Suitable for
Industrial automation and control systems
Integration of pushbuttons and signaling devices into PROFINET networks
Control panels requiring high-density device connectivity
Applications where reduced wiring and simplified maintenance are required
When it may not be suitable
This module is specifically designed for use within the SIRIUS ACT ecosystem and may not be compatible with non-Siemens proprietary signaling hardware. It is not intended for applications requiring communication protocols other than PROFINET, such as Modbus or EtherNet/IP, without the use of additional gateways.
Key specifications
Supply voltage: 24V DC
Communication protocol: PROFINET
Connection type: Spring-type terminals
Mounting type: Front plate mounting
Capacity: Up to 20 terminal modules connectable
How to use
The module is designed for straightforward installation using a snap-on concept that allows for one-handed mounting without the need for specialized tools. Begin by securing the module to the front plate of your control panel. Once mounted, connect the signaling or actuating elements to the module using the spring-type terminals. Ensure that the wiring is organized according to your system diagram. Finally, connect the PROFINET network cable to the interface port to establish communication with your controller. Always verify that the power supply is disconnected before performing any wiring tasks.
What to consider before purchase
Ensure your control system supports the PROFINET communication protocol.
Verify that the total number of connected terminal modules does not exceed the capacity limit of 20.
Confirm that the 24V DC power supply is compatible with your existing infrastructure.
Check the physical space requirements on your control panel for front-plate mounting.
Usage recommendations
For optimal performance and longevity, ensure the module is installed in an environment that adheres to the specified protection ratings. Regularly inspect the spring-type terminal connections during routine maintenance to ensure they remain secure and free from debris.
