Product Description:

The BTV20.3SA-28B-33C-D-FW is a machine operator panel produced by Bosch Rexroth Indramat within the BTV20 Machine Operator Panels series. It belongs to the wider BTV Panel product family and is identified within product line 20. The unit provides a combined display and input station for numerical control and PLC-based systems. Its role in industrial automation is to present status data, accept operator commands, and relay those commands to the drive or motion controller while consolidating the necessary control elements into a single enclosure.

Core computing resources on the panel follow the base system configuration of a minimum 300 MHz CPU aided by 128 MB RAM. Mass storage for the operating environment is specified as a minimum 3 GB HDD, giving space for the control software, diagnostic logs, and part programs. A removable 3.5-inch 1.44 MB disk drive is mounted on the front to load small files from legacy media. The unit is powered from factory mains spanning AC 115 to 230 V, and internal power-supply circuitry maintains regulation across that range while accommodating a supply frequency of 50 to 60 Hz. This input range allows installation in panels that already distribute either North American or European utility voltages without an external transformer.

Operator interaction is handled through a standard keyboard coupled with 16 machine function keys that can be mapped to axis homing, tool change, or program start. The panel uses the ISP function type, so it can host Indramat System Programming modules without an external PC. Design level 3 of the housing brings revised mounting flanges that match current cabinet cutouts, and the available memory supports larger HMI screens than earlier builds. Firmware is not supplied preloaded and must be ordered separately so the installed revision matches the target control strategy.
