Product Description:

The BTV20.2SA-64B-10C-D-FW is an operator interface unit produced by Bosch Rexroth Indramat for the BTV20 Machine Operator Panels series. The panel serves as the human-machine link for CNC and PLC-based systems, combining a display, membrane keys, and software-driven soft functions so machine states can be entered or observed directly at the cabinet door or pendant station. Within a production line, it replaces discrete push buttons and indicator lamps, allowing context-sensitive menus and numeric data entry for motion and process parameters.

The panel accepts an input of AC 115 to 230 V, and its wide supply range is paired with a mains frequency window of 50 to 60 Hz, allowing the device to be wired to single-phase control transformers in many regions. Internal processing tasks rely on 64 MB of SDRAM, which stores the real-time operating kernel, graphic objects, and current machine variables during operation. A bank of 16 machine function keys sits below the screen, and each key can be mapped to a PLC bit so frequently used commands such as cycle start or feed hold can be triggered without navigating the on-screen menu. Long-term recipe data can be loaded through the built-in 3.5-inch disk drive, which uses 1.44 MB floppy disks for data transfer.

Application software requires at least 1 GB of mass storage and a CPU clock of at least 200 MHz, figures that support PC-based simulation before the project is transferred to the actual panel. The control logic is executed through the panel’s ISP function type, which combines visualization and sequence processing in one housing. A membrane keypad marked as Standard provides tactile feedback while maintaining a sealed front surface. Design level 2 indicates the second mechanical revision in the BTV panel family, and product line 20 identifies this model class within the broader operator-panel range.
