The base unit XVB7C21M of the Harmony XVB7 series from Schneider Electric is a modular signal device for visual and acoustic indication of operating states in industrial applications. It serves as a basic element for a custom-configurable light column with a mounting diameter of 70 mm and allows the installation of up to four modules, with possible combinations including three light elements and one buzzer or four light elements. The device is designed for use in environments with high requirements for protection rating and robustness, and is particularly suitable for areas such as automotive industry, machine tools, or material handling systems.

Applications
This base unit is designed for use in industrial environments where clear and reliable signaling is required. The modular design enables flexible adaptation to different indication functions, such as combining with various light elements in colors like red, green, blue, orange, white, or gray, as well as with acoustic signals. Applications range from simple status indication to complex warning and alarm functions in production systems.

Functions and Equipment in Detail
The device features an integrated cover and is finished in dark gray, with the housing made of polycarbonate. Electrical supply is via a voltage of 100 to 240 V AC (50/60 Hz) or 120 V DC. The current consumption is 3 mA, and the maximum output current is 230 mA. Connections are made via Push-In terminals suitable for cross-sections from 0.34 to 1.5 mm², allowing both cables with and without wire end ferrules to be connected. Cable entry is from the bottom.

Technology Explained Simply
The assembly is designed for use in harsh environments and offers an IP66 protection rating, meaning it is dust- and water-tight and also suitable for outdoor use. The operating ambient temperature ranges from -25 °C to +60 °C, while the storage temperature ranges from -40 °C to +70 °C. Vibration resistance is 6 gn with an amplitude of ± 0.5 mm in the frequency range of 10 to 500 Hz, and shock resistance is 30 gn for a duration of 6 ms. The rated insulation voltage is 264 V, and the impulse voltage withstand is specified as 2.5 kV. The protection class for electric shock is Class II.

Compatibility and Accessories
The base unit is compatible with a wide range of light elements and signal modules from the Harmony XVB7 series, including light elements in various colors and operating modes (steady light, flashing light, strobe light) as well as acoustic signals such as buzzers. It can be combined with mounting accessories such as mounting brackets (e.g. XVZ100T, XVZ250T) or mounting plates (e.g. XVZ11) to enable flexible installation on various surfaces. Mounting is done via direct or pipe mounting, with positioning possible in both upright and inverted orientations.

Mounting and Installation
Mounting is tool-free and therefore quick and easy to perform. The Push-In terminals allow for fast and secure connection of the wires. Cable entry is from the bottom, supporting clean and orderly wiring. Fixing is either directly to the surface or via a pipe, with mounting orientation possible in both upright and inverted positions.

Advantages in Operation
The base unit offers high reliability and longevity due to robust materials and a high protection rating. The modular design allows flexible adaptation to different requirements without needing to replace the entire device. The integrated cover protects internal components from contamination and mechanical impacts. Certifications according to UL 60947-5-1, IEC 60947-5-1, and CSA C22.2 No. 60947-5-1, as well as product certifications cULus, CCC, RCM, UKCA, and CE, ensure suitability for international use. Pollution degree class 2 and environmental influence class UL type 4X/13 highlight suitability for industrial applications with increased environmental requirements.
