Product Description:

The BTV20.3EA-28B-44C-S-FW operator panel is produced by Bosch Rexroth Indramat within the BTV20 Machine Operator Panels series. This unit combines a graphical display, an integral keyboard, and an I/O interface to serve as the human-machine link for CNC and PLC-controlled machining centers. By placing machine commands and process feedback in one enclosure, it helps the user monitor operating states, enter commands, and respond to alarms from a single location. It is suited to applications where centralized operator access is needed for machine status, manual input, and screen-based supervision during normal production.

The panel is identified as Design 3, which is a build level used in the line 20 platform. It accepts an input supply of AC 115 to 230 V and handles line frequencies from 50 to 60 Hz, allowing direct connection to single-phase plant power without an external transformer. Operators have access to 16 machine function keys, each with tactile feedback and status LEDs for frequently used commands. Runtime data and graphical screens are stored in 128 MB of SDRAM, which supports mid-size HMI projects with language tables, alarm lists, and basic motion diagnostics. This arrangement allows the panel to present process information clearly while keeping routine control actions on the front of the machine.

For removable storage, the unit provides a Smart Card interface, allowing recipes and backup files to be exchanged without opening the housing. The operator input surface combines a standard keyboard with navigation keys, so text entry and parameter editing can be done directly on the panel instead of through an external PC. The keyboard layout supports direct entry of names, values, and menu selections during setup and daily operation. The MTA export version uses labeling and key legends intended for international delivery requirements. The unit is part of the BTV Panel product family.
