## Summary description

The Siemens 3SU1401-2BB50-3AA0 is a high-quality blue LED module designed for industrial control panels and signaling applications. It operates on a 24V AC/DC voltage and features reliable spring-loaded terminals for secure and efficient installation. This component is part of the SIRIUS ACT series, ensuring durability and compatibility for various automation and human-machine interface systems.

## Long description

The Siemens LED module is a high-performance signaling component designed for integration with SIRIUS ACT pushbuttons and indicator lights. This blue LED module provides clear, high-luminosity visual feedback, utilizing energy-efficient LED technology to ensure long-lasting and reliable operation in demanding industrial environments. Engineered for versatility, it supports a 24V AC/DC voltage range and is built to withstand harsh conditions, including exposure to dust, oils, and caustic solutions.
Advantages
This module features an innovative snap-on design that allows for quick, one-handed installation without the need for specialized tools. The integrated twist prevention ensures that the unit remains securely in place once mounted. Its robust construction provides a high degree of protection, making it suitable for both indoor and outdoor industrial applications, including environments where high-pressure cleaning is required. The use of spring-loaded terminals facilitates a secure and efficient electrical connection, reducing installation time and maintenance requirements.
Suitable for
Industrial control panels
Human-machine interface (HMI) systems
Signaling and status indication for automation equipment
Outdoor control stations requiring high ingress protection
When it may not be suitable
This module is specifically designed for the SIRIUS ACT series and may not be compatible with other pushbutton or signaling systems. It is intended for 24V AC/DC power supplies and should not be connected to higher voltage circuits, as this will cause permanent damage to the LED component.
Key specifications
Voltage: 24V AC/DC
Color: Blue
Connection type: Spring-loaded terminals
Mounting type: Floor mounting
Series: SIRIUS ACT
How to use
To install the module, ensure the power supply is disconnected. The snap-on mechanism allows the module to be attached to the corresponding SIRIUS ACT holder or enclosure base with a simple click. Once the module is seated, insert the wires into the spring-loaded terminals. The spring-loaded design automatically secures the wire, providing a vibration-resistant connection. After installation, verify the connection by applying the rated 24V AC/DC voltage to confirm the LED illuminates correctly.
What to consider before purchase
Verify that your existing control system provides a 24V AC/DC power supply.
Ensure compatibility with your specific SIRIUS ACT pushbutton or indicator light housing.
Check the mounting space requirements within your control panel or enclosure.
Usage recommendations
For optimal performance and longevity, ensure that the module is installed in an environment that does not exceed the specified temperature ratings for the SIRIUS ACT series. Regularly inspect the spring-loaded terminal connections during routine maintenance to ensure they remain secure in high-vibration environments.
