Product Description:

The BTV20.2SA-24B-55D-D-FW is an operator panel manufactured by Bosch Rexroth Indramat within the BTV20 Machine Operator Panels series. It serves as a decentralized human-machine interface for numerical control systems, allowing direct command entry and status feedback in automated machining cells. By combining display, keyboard, and communication hardware in one housing, the unit reduces cabinet wiring and provides a dedicated point for machine-level parameter adjustment and diagnostics.

The panel is powered from a DC 24 V supply, so it can share the low-voltage power rail already present in most control cabinets. A baseboard clocked at 1 GHz or higher handles soft-PLC tasks and screen updates, while the integrated RS485 port provides deterministic communication with drives, I/O islands, or legacy PLCs. System memory includes 1024 MB of DDR, giving adequate buffer space for part programs and operator messages without relying on external storage. For machine operation, the front panel provides 16 machine function keys that can be mapped to frequently used cycles, coolant commands, or axis jog modes, and a standard membrane keyboard for alphanumeric data entry completes the control surface.

Mechanical layout follows Design 2, meaning mounting points and bezel dimensions match the second iteration of the BTV20 enclosure. Control logic is executed under the panel's ISP function layer, identified by the ISP designation, which separates real-time tasks from the graphical shell. Nonvolatile storage is supplied by a front-accessible 3.5-inch 1.44 MB disk drive; this allows quick transfer of NC files in facilities where network access is restricted. Firmware is not factory-flashed and must be ordered as a separate sub-position so that the correct language set and machine option bits can be installed. Within the wider BTV Panel family, the device occupies product line 20, placing it in the mid-performance tier of Indramat operator interfaces.
