Product Description:

The BTV20.3AA-28B-33C-D-FW operator panel is produced by Bosch Rexroth Indramat and belongs to the BTV20 Machine Operator Panels series. Designed as a combined display and keyboard station, the unit serves as a human-machine interface in automated machining cells, allowing the control system to accept keyed commands and return status information during operation. It connects to drives and PLCs over proprietary buses, so operators can select cycles, view diagnostics, and edit programs directly from the panel. By combining the display and keypad in one housing, it reduces the need for separate input devices on the machine front. This arrangement supports direct machine interaction at the point of use and keeps routine control functions close to the process.

To start the installed operating environment, the base computer behind the panel requires at least 3 GB HDD of storage and a 300 MHz CPU. For active runtime variables and screen buffering, the electronics include 128 MB of RAM. Power is supplied through AC 115 to 230 V at 50 to 60 Hz, which allows connection to standard control cabinets without a step-down transformer. A bank of 16 machine function keys is arranged around the screen, and each key can be assigned to a CNC sequence, axis enable, or auxiliary action. This combination supports basic visualization, menu handling, and command entry without requiring a high-performance computer platform.

The hardware configuration is listed as Design 3, which is the third mechanical layout in the product line and affects connector orientation and housing depth. For removable media, the front door contains a 3.5-inch disk drive that reads and writes 1.44 MB disks, which can still be used to transfer small NC programs when network access is limited. Its front-door media access keeps small file transfers available at the panel itself. The panel uses the MTA function type for motion and tooling command handling when paired with compatible drive controllers.
