Product Description:

The BTV20.4AA-24B-55C-E-FW operator panel is produced by Bosch Rexroth Indramat within the BTV20 Machine Operator Panels series. It combines a display, keypad, and communication functions in one compact unit for mounting on the front of CNC or PLC-controlled equipment. In normal service, the panel acts as the point where the operator enters commands, selects machine functions, and monitors status messages returned by the control system. Its integrated layout helps keep the operator interface close to the machine process without requiring a separate industrial computer enclosure. This arrangement is suited to machine tools and other automation stations that need a dedicated local interface for setup and routine operation.

Processing tasks are handled by a base system rated at 1 GHz minimum, which provides adequate cycle time for screen refresh, menu handling, and diagnostic routines. An onboard RS485 channel links the panel to compatible control hardware without requiring an extra serial adapter. Volatile memory totals 1024 MB, so larger part programs, message buffers, and alarm histories can remain available during operation. The front panel includes 16 machine function keys for direct access to common commands, and power enters the unit at AC 115 to 230 V for use on common single-phase mains. This wide input range makes the panel easier to integrate into equipment built for different regional power systems.

Clock timing and internal switching remain synchronized because the power stage accepts 50 to 60 Hz mains frequency. Removable storage is provided by a built-in 3.5-inch floppy drive, which reads and writes 1.44 MB diskettes when network-based transfer is not available. The housing uses Design 4, and the front overlay follows the MTA functional classification so key legends and signal assignments remain consistent with matching panel layouts in the product line. This format supports applications that still rely on local media exchange and dedicated hard keys at the operator station.
