Product Description:

The Bosch Rexroth Indramat BTV20.3EA-28B-33C-D-FW is an operator interface in the BTV20 Machine Operator Panels series. Identified in product line 20, this unit combines a display, keyboard, and internal PC resources so a CNC or PLC can be managed directly from the machine frame. It serves as the human-machine interface in automated cells where program selection, parameter entry, and diagnostic viewing must be handled close to the equipment. The panel also allows operators to review alarms and adjust machine settings without moving to a separate control station.

Electrical integration is straightforward because the panel accepts AC 115 to 230 V mains and supports line frequencies of 50 to 60 Hz. This wide input range helps the unit fit installations that use different standard supply voltages. Its PC board is equipped with 128 MB of RAM, which helps operator menus and motion programs load smoothly during normal use. When the panel is connected to an external industrial PC, the base system requires a minimum 3 GB hard drive and a minimum 300 MHz CPU. Operating software is ordered separately, allowing the panel to be matched to the required language package and application. A standard keyboard provides tactile feedback during numeric entry and menu navigation, reducing reliance on touch-only control.

On the front panel, operators have access to 16 machine function keys that can be mapped directly to PLC bits for cycle start, axis jog, or macro calls. Physical keys also support repeated operation when touch input is less practical. A front-mounted 3.5-inch, 1.44 MB disk drive supports loading part programs from legacy floppy media and allows older file libraries to remain usable. The hardware follows Design 3, which keeps connector placement and mounting dimensions consistent with earlier revisions. The unit is supplied as the MTA export version, so its I/O allocation and labeling suit international control cabinet requirements while preserving the standard BTV keyboard layout.
