Product Description:

The BTV20.3CA-28B-33C-D-FW is a human-machine interface unit from Bosch Rexroth Indramat in the BTV20 Machine Operator Panels series. The panel combines a display, keyboard, and integrated computer so users can issue commands, monitor process status, and adjust parameters directly at the machine. Within an automation line, it links controllers and drives and provides local access to diagnostics, motion sequences, operating data, and status messages without requiring a separate industrial PC. Its compact format suits CNC- and PLC-controlled equipment where a front-mounted interface must remain available at the work cell throughout normal operation.

The panel accepts an input supply of AC 115 to 230 V, which allows connection to common single-phase control power. It operates at mains frequencies from 50 to 60 Hz. The embedded computer uses a 300 MHz CPU, giving enough performance for screen refresh tasks, control communication, and fieldbus traffic. It is equipped with 128 MB RAM for runtime data, motion programs, and diagnostic buffers used by the Windows-based environment. Local storage begins with a 3 GB HDD, which provides space for the operating system, application files, and locally stored user data.

The operator interface includes 16 machine function keys that can be assigned to tasks such as cycle start, axis jog, or tool-change commands, while the standard keyboard supports alphanumeric entry for edits and setup values. A built-in 3.5-inch 1.44 MB disk drive supports loading files from legacy media when network access is not available. The enclosure follows Design 3, which matches the mounting cutout and installation depth used by later BTV housings. The panel uses the MTC function type so it can handle motion-related operation, technology cycles, and process diagnostics with compatible Rexroth control systems.
