Product Description:

The BTV20.3PA-28B-44C-D-FW is an operator panel produced by Bosch Rexroth Indramat within the BTV20 Machine Operator Panels series. It serves as the human-machine interface for numerical control or PLC-based automation, giving operators a single point for machine input and status viewing. The integrated display, keyboard, and embedded controller hardware allow one enclosure to handle visualization tasks, show process information and alarms, and send operating commands directly to drives, I/O racks, or higher-level control networks on the factory floor.

The front membrane includes 16 machine function keys that can be mapped to frequently used cycle, axis, or safety commands, reducing operator movement across layered screens. Internally, the panel carries 128 MB of RAM to hold real-time operating variables and user interface graphics without paging delays. Primary mass storage is provided by a 3.5-inch drive that accepts 1.44 MB DOS-formatted diskettes for recipe loading or software updates. Power is supplied from AC 115 to 230 V, and the built-in power supply remains stable across a line frequency range of 50 to 60 Hz. This input range supports installation on common industrial power systems without requiring a separate external power converter.

The unit is built to Design 3, which indicates the enclosure revision and connector layout used for this version. The front panel includes a standard keyboard, so programming shortcuts follow the typical PC scan code set and support familiar key-based input. Functionally, the unit is classified as an IPC, so the CPU, RAM, and fieldbus interfaces reside on the same motherboard instead of a separate industrial computer. It belongs to Product Line 20, which keeps it mechanically compatible with earlier BTV generation mounting frames and helps it fit established panel cutouts.
