Product Description:

The BTV20.3PA-28B-44C-S-FW operator panel is produced by Bosch Rexroth Indramat within the BTV20 Machine Operator Panels series. As a human-machine interface, the unit combines a display, control keys, and integrated PC functionality so CNC or PLC systems can be monitored directly at the machine. In automated production cells, it provides the access point for running parts programs, acknowledging alarms, and adjusting process parameters without opening the control cabinet. This arrangement keeps machine interaction local to the operating station and supports routine control tasks from the panel front.

For electrical integration, the panel accepts a single-phase supply of AC 115 to 230 V, 50 to 60 Hz, allowing use on a wide range of plant power systems. The front fascia carries 16 machine function keys, each mapped to PLC bits so commonly used cycles can be triggered with a single press. Internal computing resources include 128 MB of DRAM for the active NC kernel and visualization data. Long-term recipes or parameter sets can be stored through the Smart Card interface, which allows data to be moved between stations when the application requires the same setup at multiple machines. Control tasks are handled by an industrial PC core classified as IPC, so the panel supports PC-based control and visualization functions in one housing.

The hardware layout follows Design 3, so the processor board, power supply module, and I/O backplane are integrated into one compact housing that fits the panel cutout. A Standard membrane keyboard below the display provides tactile input for routine machine commands. The identifier places the unit in product line 20, which gives it the connector arrangement and enclosure format used across BTV20 variants. Application code is loaded from flash memory, so operating data remains available after normal power cycling. The compact layout also reduces the number of separate modules required at the front of the machine.
