Product Description:

The BTV20.3EA-28B-44C-D-FW operator panel is produced by Bosch Rexroth Indramat as part of the BTV20 Machine Operator Panels series. It serves as a human-machine interface for numerical control equipment, combining display electronics and a sealed keypad in one housing for machining centers, transfer systems, and other automated stations. The panel routes operator inputs directly to the drive or PLC layer, which streamlines routine commands, setup functions, and diagnostic access on the plant floor. Because the screen and keypad are integrated into one front-mounted unit, status viewing and command entry take place at the same location.

The panel ships in design version 3, which sets the enclosure dimensions and connector placement for cabinet integration. It accepts a supply of AC 115 to 230 V, 50 to 60 Hz, allowing connection to standard control transformers without external adapters. A membrane section with 16 machine function keys can be mapped to rapid-access NC or PLC commands, which reduces menu navigation during production changes. System memory includes 128 MB of SDRAM to buffer variable data and interim process values, supporting screen activity and temporary process handling. Long-term file transfer is handled through a mounted 3.5-inch, 1.44 MB disk drive, providing removable media when network access is restricted. This arrangement supports offline transfer of machine files and stored records without requiring a permanent network connection.

Within the broader BTV Panel product family, the unit carries product line identifier 20, which marks its display size and I/O scale relative to earlier models. The keyboard follows the Standard layout, so operators familiar with older BTV panels encounter no change in key placement or tactile response. That familiar arrangement helps reduce input errors when similar panels are used across multiple machines. Its panel function type is MTA, export version, which indicates a variant intended for non-EU markets. This version uses region-specific legends and safety markings while keeping the same basic operating role as other panels.
