Product Description:

The BTV20.2SA-28B-10D-D-FW operator panel is produced by Bosch Rexroth Indramat as part of the BTV20 Machine Operator Panels series. This panel serves as the local human-machine interface for machine tools and automation cells, allowing the controller to display status information and accept operator commands on the shop floor. On production equipment, it presents operating states, alarms, and menu-based screens in one front-mounted interface. That arrangement lets the machine controller and the operator exchange information without a separate desktop computer or handheld terminal.

The base system calls for a minimum storage capacity of 1 GB and a processor clock speed of 200 MHz. These values describe the minimum hardware performance needed for software loading and basic visualization tasks. A factory-installed 128 MB RAM module supports active program execution and buffering of process variables. That memory helps the panel handle screen changes and process data during normal operation. The electronics are supplied from a single DC 24 V source, which simplifies cabinet wiring and fits common industrial control power schemes. For removable media, the front access door houses a 3.5-inch 1.44 MB disk drive, allowing data transfer or logging when network access is unavailable.

The operator section follows Design 2, a variant that combines a numerical keypad with a block of 16 machine function keys so users can trigger predefined PLC sequences without navigating menus. The dedicated keys support direct access to repetitive machine functions that would otherwise require additional screen changes. The internal control logic is classified under the integrated screen and processor panel function, identified here by the code ISP, which means the display, keyboard, and CPU are housed in one enclosure. Within the wider BTV panel family, this unit belongs to product line 20, indicating compatibility with VPP and VDP visualization software versions developed for that line. The standard membrane keyboard layout provides alphanumeric entry and cursor control for routine machine interaction.
