Product Description:
The BTV20.3SA-28B-33C-S-FW machine operator panel is made by Bosch Rexroth for use in control systems. The panel integrates machine control keys and navigation features into a single hardware unit. It allows user interaction and operational control through a built-in keypad and LCD interface. The panel is built for machine-level interaction within industrial automation applications.
The BTV20.3SA-28B-33C-S-FW machine operator panel works on a 24 V DC supply that ranges between 20 to 30 V and has a maximum current consumption of 400 mA. The LCD display has a resolution of 128 x 64 pixels that allows full graphics in black and white and includes LED background illumination. The visible screen area spans 68 x 37 mm. It includes combined navigation keys, function keys from F1 to F10, and machine-specific buttons such as Start/Tippen and Sofort Halt. Alphanumeric and symbol keys are available for code and parameter input. The unit offers modes like single operating, standby, and error reset. Control keys include OK, ESC, PROG, CTRL, ALT, TAB, and DEL. The BTV20.3SA-28B-33C-S-FW offers integrated RS-485 and RS-232 interfaces that provide serial connectivity. The bottom side has multiple I/O ports that include DB-9 and DB-25 connectors, likely used for RS232, RS485, or private bus systems. The internal power supply and onboard cooling fan are apparent, suggesting that processing functions are handled locally without external hardware dependency.
The BTV20.3SA-28B-33C-S-FW front panel has IP 65 protection that stops dust and liquid ingress during operation. The housing has an IP20 grade, which means that solid objects bigger than 12.5 mm can not get in. The bottom side has an integrated cooling system that keeps the temperature stable during long periods of use. There are setup, number reset, and run-through keys on the panel. The machine operator panel can be used for both CNC programming and PLC-based tasks.
