Product Description:

The BTV20.3PA-28B-45C-S-FW operator panel is produced by Bosch Rexroth Indramat within the BTV20 Machine Operator Panels series. As an integrated human-machine interface, it allows machine builders to issue commands, monitor process status, and navigate control menus directly at the installation site. The unit combines keyboard entry with soft keys, giving operators immediate access to motion and diagnostic functions on numerically controlled equipment and other automated stations. This arrangement keeps routine inputs and screen-based feedback in one place, which is useful where the panel must stay close to the machine process.

The base electronics incorporate a minimum 700 MHz processor that handles visualization, program execution, and communication tasks, while an onboard RS-485 port provides a low-level channel for drive or PLC data exchange. System memory includes 128 MB of RAM, enough to buffer operating system components, application code, and real-time variables without external expansion during normal panel operation. User data such as part programs and backup parameters can be stored through a Smart Card interface, which provides removable media access for loading or transferring application files. Direct machine interaction is supported by 16 machine function keys, allowing quick access to frequently used commands such as cycle start, feed hold, or axis jog without relying only on on-screen navigation.

Mechanical layout follows Design 3, a format that matches the cutout and mounting scheme used across product line 20. Internally, the panel is classified as an industrial PC, so its panel function type is listed as IPC, which supports standard operating systems and panel-based control tasks. This architecture allows the unit to handle visualization duties alongside communication and local input functions in a single housing. Power may be supplied from AC 115 to 230 V, 50 to 60 Hz, allowing installation in both North American and international cabinets without a dedicated transformer.
