Product Description:

The BTV20.4AA-24B-55C-D-FW is an operator panel produced by Bosch Rexroth Indramat for the BTV20 Machine Operator Panels series. Intended for machine tools and automation stations, the panel combines visual feedback with tactile commands so an operator can start, stop, and monitor connected axes or processes from a single front end. By integrating display electronics with an industrial keyboard and serial interfaces, the unit serves as the human-machine interface for local machine control. This arrangement keeps status messages and manual commands available at the same point on the machine during setup and routine operation.

The panel ships with a base system that includes a processor rated at minimum 1 GHz and RS485 communication, giving it local computing capacity and a standard serial link for drive or PLC data exchange. Power is accepted from AC 115 to 230 V supplies at 50 to 60 Hz, which allows the device to operate from common cabinet mains sources. A built-in memory module of 1024 MB stores part programs, screen data, and diagnostic information, while a 3.5-inch, 1.44 MB disk drive provides removable storage for legacy files. For direct machine actuation, the front membrane includes 16 machine function keys, and their scan codes are processed by the panel CPU instead of an external controller. Because the processing and interface functions are onboard, the panel can handle screen management and command entry without relying on a separate operator console.

The panel is Design 4 and belongs to Product line 20. Its control logic follows the MTA panel function type, so the unit supports message display, tool data entry, and axis jog commands from the front panel. A factory-mounted Standard keyboard provides alphanumeric input for parameter entry and operating commands. Operators can enter identifiers, values, and short text responses directly at the panel during normal machine use.
