## Long description

The Siemens SIRIUS ACT LED module is a high-performance signaling component designed for industrial control environments. This blue LED module operates at 5V DC and is specifically engineered for integration onto printed circuit boards (PCB) using solder pin terminals. As part of the robust SIRIUS ACT series, it provides reliable visual status indication for pushbuttons and indicator lights, ensuring clear communication of system states in demanding operational settings.
Advantages
This LED module stands out due to its energy-efficient technology, which delivers high luminosity while maintaining low power consumption. The component is built to withstand harsh industrial conditions, offering resistance to dust, oils, and caustic substances. Its design facilitates seamless integration into the broader SIRIUS ACT ecosystem, allowing for quick and secure installation. The high-quality construction ensures long-term reliability and consistent performance, making it an ideal choice for professional control panel configurations.
Suitable for
Industrial control panels and signaling systems
PCB-based electronic control assemblies
Visual status indication for pushbuttons and indicator lights
Automation equipment requiring 5V DC signaling
When it may not be suitable
This module is designed specifically for PCB mounting via solder pins and is not suitable for applications requiring standard screw terminals or direct panel-mount wiring without a circuit board. It is also limited to a 5V DC power supply and cannot be used in systems operating at higher voltages without appropriate voltage regulation.
Key specifications
Color: Blue
Operating voltage: 5V DC
Connection type: Solder pins
Mounting: Printed circuit board (PCB)
Series: SIRIUS ACT
How to use
The module is intended for installation onto a printed circuit board. Ensure the board layout matches the solder pin configuration of the module. Once positioned, solder the pins to the designated pads on the PCB to establish a secure electrical and mechanical connection. After installation, verify that the power supply provides a stable 5V DC input to prevent damage to the LED component.
What to consider before purchase
Verify that your control system provides a 5V DC power supply.
Ensure your assembly process supports solder pin connections on a PCB.
Check the compatibility of the module with your existing SIRIUS ACT pushbutton or indicator housing.
Usage recommendations
For optimal performance and longevity, ensure the module is protected from excessive heat during the soldering process. Always verify the polarity of the power supply connection before energizing the circuit to prevent damage to the LED.
