Product Description:

The BTV20.3CA-28B-44C-D-FW operator panel is produced by Bosch Rexroth Indramat and belongs to the BTV20 Machine Operator Panels series. This panel combines a display, keypad, and drive interface in one housing, giving CNC or PLC-based equipment a compact human-machine interface. It provides direct machine status feedback and lets the operator start cycles, acknowledge alarms, and change process parameters without opening the control cabinet. Because the operating and display functions are integrated into one front-panel unit, external control elements can be reduced on the machine door. The panel is intended for stations where command entry and status visualization need to remain available at the point of operation.

It accepts an input supply of AC 115 to 230 V, 50 to 60 Hz, so it can be connected to standard single-phase control power without an external transformer. Its keypad includes 16 machine function keys, and each key can be assigned in the control program to commonly used commands. The integrated memory includes 128 MB of RAM for the operating system, graphical elements, and active user data during runtime. For removable storage, the panel is equipped with a mounted 3.5-inch, 1.44 MB disk drive, which allows boot files or logs to be read from standard floppy media. User text entry is handled through a standard keyboard layout, which supports familiar operation and straightforward input of machine data.

The control logic is classified as MTC, which means the panel can handle basic motion and technology functions locally before higher-level tasks are passed to the main CNC. This arrangement supports applications where simple interface-related processing is performed at the panel while the central control manages broader machine coordination. Bosch Rexroth identifies this unit as Design revision 3. It is assigned to Product Line 20 within the operator interface range and carries the family descriptor BTV Panel. That family designation keeps related mounting frames and cable accessories within the same interface group.
