Product Description:

The BTV20.2SA-28B-11C-D-FW machine operator panel is manufactured by Bosch Rexroth Indramat for use in the BTV20 Machine Operator Panels series. It serves as an interactive front end for machining centers and automated assembly stations, where it provides a direct interface for routine machine supervision in automated cells. Through the panel, the operator can supervise motion sequences, enter job data, acknowledge system messages, and interact with the machine without a separate PC at the work area.

The panel runs on an input supply of AC 115 to 230 V, 50 to 60 Hz, so it can be wired to common single-phase control transformers without additional converters. A dedicated system board carries 128 MB of RAM, giving the resident software room to buffer part programs and diagnostic logs during normal operation. Sixteen illuminated machine function keys are arranged in one column, and each key can be mapped to a PLC bit for tool change, cycle start, or other frequently used actions at the machine. A 3.5-inch disk drive with 1.44 MB capacity is mounted on the front panel, providing removable storage for parameter sets through standard DOS formats. The panel is classified as ISP, so the keyboard, display, and computer subassemblies share one enclosure, which simplifies wiring and cabinet layout.

The hardware baseline includes minimum 1 GB, 200 MHz, and RS485 support, which provides the CPU and backplane resources needed to load the panel operating image from flash or disk. The standard keyboard layout includes alphanumeric keys plus motion overrides, enabling direct value entry and motion-related input without an external PC during setup or routine use. Mechanical configuration code 2 indicates housing dimensions that fit the 19-inch front plate openings used throughout the series, while product line designation 20 places this model among mid-performance BTV units intended for milling or turning centers. Software loaded through the onboard drive becomes active at the next power cycle.
