The LR6-USB Signal Tower is designed to connect to a PC or HMI and receive power and commands over a single USB connection. Featuring bright LEDs, the tower consumes little power and is expandable up to five LED color modules. It supports multiple operating platforms, including Windows and Linux. Four flash patterns and four alarm sounds are built-in to further provide clearer indication. The tower is available as modular segments, allowing users to customize the device to their specific application. Flexible mounting options are available, including brackets and poles to match the LR6-USB off-white and black base options.
