Product Description:

The BTV20.3AA-56B-44C-D-FW is an operator panel manufactured by Bosch Rexroth Indramat and assigned to the BTV20 Machine Operator Panels series. The unit serves as the primary interface between numerical control or programmable logic devices and machine operators, combining hardware keys, display electronics, and local control functions to issue commands, acknowledge alarms, and monitor machining procedures in industrial automation cells. By integrating visualization and data entry in one enclosure, it reduces external hardware and supports centralized operation of multi-axis production equipment.

The panel follows Design 3, so the housing and connector arrangement match the third-generation layout used in the series. Operators receive direct control through 16 machine function keys arranged in two rows, and each key can be addressed by the software. Electrical power is accepted at AC 115 to 230 V, 50 to 60 Hz, allowing connection to common single-phase mains without an external transformer. A standard keyboard supports alphanumeric entry during program editing. For removable data, the front panel includes a 3.5-inch, 1.44 MB disk drive for machine programs, backups, or update files. All control logic operates under the function class MTA, which identifies terminals that run the application locally rather than on a remote PC.

The system software is ordered separately rather than supplied as a permanent part of the hardware, allowing the panel to be matched with different controller generations and loaded through the floppy drive when required. The device belongs to the BTV Panel family, which keeps it compatible with legacy mounting cutouts and standard communication cabling used across that range. Within that product structure, it is identified as product line 20, placing the terminal in the mid-range of the operator interface range. The enclosure combines display and input functions in a single front-mounted unit, which helps keep the control station compact while preserving direct access to machine commands and stored data.
