Product Description:

The BTV20.3AA-28B-45C-D-FW is an operator interface produced by Bosch Rexroth Indramat for the BTV20 Machine Operator Panels series. It serves as the human-machine interface in automated production cells by combining a display, keypad input, and motion-related entry functions in one panel. This arrangement lets operators send commands to CNC or PLC systems without relying on separate terminals or external selector stations. It can be used for routine interactions such as selecting jobs, acknowledging faults, entering values, and navigating control screens during normal machine operation. Its integrated format also reduces the need for multiple standalone input devices on the machine.

The base system has a minimum processing speed of 700 MHz and includes an onboard RS485 interface for direct communication with compatible axes and peripheral devices. Power is supplied at AC 115 to 230 V, and the unit operates on a mains frequency of 50 to 60 Hz. For manual machine actions, the panel provides 16 machine function keys that can be assigned to tasks such as clamping, coolant control, or mode selection. A standard membrane keyboard completes the numeric and alphanumeric input functions, giving the panel a practical layout for entering commands, parameter values, and production data. This combination supports both fixed machine actions and flexible text or number entry from the same front interface.

The hardware platform uses Design 3, so the enclosure and connector arrangement follow the layout used for this version of the panel. Primary removable storage is a 3.5 inch disk drive with a capacity of 1.44 MB for transferring programs or related panel files. Panel functionality is classified as MTA, which means motion, terminal, and automation functions are combined in one operating environment. This allows the panel to handle operator interaction and control-related input from a single unit rather than splitting those tasks across multiple devices. The result is a compact interface that supports machine operation, data entry, and control access through one front-mounted panel.
