Product Description:

The BTV20.3CA-2BB-45C-D-FW operator panel is produced by Bosch Rexroth Indramat and belongs to the BTV20 Machine Operator Panels series. Within an automation cell, this human-machine interface supplies push-button, key, and display resources so CNC or PLC controllers can be commanded directly at the machine frame. Its housing and electronics are intended for front mounting on control cabinets, allowing machine builders to place motion, spindle, and auxiliary controls on one panel while reducing separate operator wiring. The panel combines local command entry with screen-based feedback, so routine actions such as mode selection, start, stop, and acknowledgment can be handled without a separate pendant.

Inside the panel, a base system configured with minimum 700 MHz with RS485 provides processing capacity for soft-PLC tasks and an RS485 channel for connected devices. The supply circuit accepts AC 115 to 230 V at 50 to 60 Hz, so the same unit can operate from common North American or European mains. Operators issue frequent cycle commands through 16 machine function keys arranged beneath the display, and each key can be assigned to an NC sequence or auxiliary function. This arrangement keeps repetitive commands easy to reach during cycle operation. A 3.5-inch, 1.44 MB disk drive is mounted internally so files can be loaded from standard floppy media. The keyboard uses a standard layout, keeping key positions familiar across similar panels.

The mechanical configuration is identified as 3, indicating the third design revision of the front panel mechanics and sealing concept. At the application layer, the panel runs the MTC function package, so tool-specific screens and context-sensitive soft keys are available for machining centers. The unit is part of the BTV Panel product family, and the hardware generation is coded as 20. This separates the application package from the physical revision and places the panel within the related control-platform components introduced during the same product cycle.
