Product Description:

The BTV20.3SA-28B-33C-S-FW operator panel is produced by Bosch Rexroth Indramat as part of the BTV20 Machine Operator Panels series. It combines an industrial PC with a membrane-style operator interface so process values can be displayed and machine commands can be entered directly at the work cell. By integrating the display, keyboard, and dedicated keys in one housing, it serves as a local human-machine interface for CNC systems, packaging equipment, and other automated machinery that requires close operator access. This layout helps keep control and visualization functions near the machine rather than in a separate cabinet station.

The unit accepts a supply of AC 115 to 230 V, 50 to 60 Hz, which supports use with common single-phase control power sources. The embedded computer requires at least 3 GB HDD and a 300 MHz CPU, so diagnostics, visualization tasks, and motion-related software can run correctly. Working memory is 128 MB, providing space for the real-time kernel, operating data, and recipe handling. Persistent data can be stored through a Smart Card interface, allowing card changes when production parts or lot settings change. Direct machine commands are available through 16 machine function keys beside the keyboard, so frequently used PLC actions can be reached without navigating through multiple screens.

The panel uses an ISP environment that links keys and screen objects to PLC variables for operator control. Mechanical variant 3 determines the housing depth and mounting stud arrangement used by this version. The integrated keyboard is standard, providing full ASCII character entry for text fields and G-code input without an external keyboard. Within the product family, line 20 indicates compatibility with specific expansion modules. Operating software is ordered separately so the installed language set and technology options can be matched to the application.
