Product Description:
The BTV20.3SA-28B-45C-D-FW is an operator terminal produced by Bosch Rexroth Indramat for the BTV20 Machine Operator Panels series. It combines visual display and membrane keypad control so that CNC or PLC equipment can be commanded from a single front panel. Within an automation cell, this unit provides the human-machine interface needed to start, stop, and supervise motion programs, place the controller in setup mode, and acknowledge alarms without opening the electrical cabinet. Its front-mounted format lets routine operating commands stay close to the machine process, which helps keep daily interaction direct and organized.
The panel accepts a supply of AC 115 to 230 V, allowing installation on either side of common North American or European mains, and it operates at line frequencies from 50 to 60 Hz. Internal computing resources include 128 MB of RAM for buffering program data, operator messages, and diagnostic logs. Its front membrane offers 16 machine function keys that can be assigned to tasks such as jog, tool change, or coolant control. A processing core rated at min. 700 MHz handles screen refresh, communication tasks, and control-related processing quickly enough for responsive operator input. This arrangement supports clear navigation between operating screens and helps the panel react promptly to changes in machine state.
Communication with drives and PLCs is handled through RS485, which supports multidrop wiring over several meters in a noisy industrial environment. A 1.44 MB 3.5-inch disk drive is installed for transferring part programs when network access is unavailable. The hardware revision is Design 3, and the panel uses the ISP function type assigned to this family. A standard keyboard layout supplements the membrane keys for manual data entry, while the display and control functions remain integrated in one operator station. This combination makes the unit suitable for machine interfaces that need local command entry, status viewing, and dependable serial communication with the connected control system.
