Product Description:

The BTV20.3PA-56B-45C-D-FW operator panel is manufactured by Bosch Rexroth Indramat within the BTV20 Machine Operator Panels series. It is an industrial PC-based human-machine interface intended for machine tool and motion control stations where parameter entry, status monitoring, and drive diagnostics must be performed locally. The panel combines computing hardware, integrated keys, and field communication inside a single housing, allowing it to execute supervisory tasks while passing commands to Rexroth drives and PLCs. Its role in automation is to present real-time process data and accept operator commands without requiring separate input hardware at the machine station.

Its base system is specified at a minimum clock speed of 700 MHz, providing enough processing capacity for graphical screen updates and fieldbus communication. Serial communication is available through RS485, enabling direct connection to drive controllers and remote I/O over long cable runs. The supply section accepts AC 115 to 230 V at 50 to 60 Hz, so the panel can operate from common single-phase industrial power sources. Working memory totals 256 MB of RAM, giving space for the operating system, application data, and active control variables during multitasking use.

For removable storage, the front-mounted 3.5-inch disk drive holds 1.44 MB, which supports transfer of program files, machine recipes, and diagnostic records. Operators interact through 16 machine function keys arranged around the screen plus a standard membrane keyboard, reducing the need for repeated menu navigation during routine machine operation. The panel is identified as an IPC type within the series, and Design 3 indicates its mechanical layout and connector placement. This arrangement allows the unit to combine local interface functions with industrial computing in one enclosure.
