Harmony XVB7 base unit, Ø70mm light tower, 24V AC/DC base with adapter and cover, grey XVB7C21B

Harmony XVB7 Signal Tower Base Module – the foundation of an effective system

This base module, part of the Harmony XVB7 series from Schneider Electric, is the foundation for building reliable and versatile signal towers. Designed for user mounting, it allows for easy creation of complete light and sound towers, tailored to specific industrial needs. With a diameter of 70mm, this base is compatible with a wide range of signaling modules, allowing you to create a visual system for warning and informing about the status of machines and processes.

Design and application

The XVB7C21B base module is powered by 24V AC/DC, providing flexibility in integration with existing electrical installations. It features pluggable terminals for easy electrical connection. Made of durable dark gray polycarbonate, it is resistant to harsh industrial conditions – impacts, dust, water and vibrations (IP66 or IP65 protection depending on the mounting method). This makes it ideal for demanding production environments where reliability and durability are key. The base is supplied with an adapter and cover, simplifying installation and ensuring an aesthetic appearance.

Advantages and benefits for installers and users

• Easy installation: The modular design allows for quick and easy creation of complete signaling towers without specialized tools.
• Versatility: Compatibility with various light and sound modules allows the system to be adapted to specific application needs.
• Durability: Resistance to external factors (IP66/IP65) ensures reliable operation even in harsh industrial conditions.
• Universal power supply: The ability to power both 24V AC and DC increases installation flexibility.
• Wide range of applications: Ideal for signaling machine status, production processes, traffic management and warning of potential hazards.
• Compliance with standards: Meets the requirements of UL 60947-5-1, IEC 60947-5-1 and CSA C22.2 No 60947-5-1 standards, guaranteeing safety and reliability. It also has CE, cULus, CCC, RCM and UKCA certificates confirming the high quality of the product.
• Energy saving: The use of LEDs minimizes energy consumption while maintaining high brightness of light signals.

Thanks to these features, the XVB7C21B base module is an optimal solution for both professional installers looking for easy-to-install and reliable components, and for end-users expecting an effective visual and sound signaling system.
