Product Description:

The C9900-L100-1814 USB accessory is produced by Beckhoff and belongs to the C9 PC Accessories series. Designed for industrial PCs, the unit connects through a standard USB interface to extend TwinCAT or Windows licensing functions and to store configuration data within an automation cell. Its compact mechanical outline and software-related identifiers allow it to be integrated into control cabinets or mounted directly on field devices where a removable, bus-powered module is preferred.

The module measures a height of 15.5 mm and has a thickness of 7.6 mm, giving a slim profile that avoids interference with neighboring connectors. Overall depth, including the protective cap, is 38.25 mm, while the exposed plug section contributes 12.5 mm to this dimension so that the USB contacts sit at the correct insertion depth. Electrical power and data are supplied via the USB 2.0 bus, eliminating the need for an external voltage line and ensuring compatibility with Beckhoff IPC front panels. These dimensions simplify routing when the installation position is variable and help maintain clearance distances in densely populated racks.

In addition to size considerations, the device withstands ambient temperatures from -25 °C up to +60 °C during operation and tolerates relative humidity levels as high as 95% RH without condensation, making it suitable for control rooms that experience seasonal climate swings. The enclosure carries an IP20 protection class, indicating finger-safe accessibility yet requiring placement in a closed cabinet for exposure to splashing liquids or dust. TwinCAT build 4018.26 or higher and Windows 11 build 4026 are the minimum software baselines, so users must verify host compatibility before use. Storage limits down to -40 °C and up to +85 °C allow the stick to be shipped with equipment or kept as a spare part without additional packaging requirements.
