Product Description:

The BTV20.3SA-28B-44C-D-FW is a machine-level operator panel produced by Bosch Rexroth Indramat within the BTV20 Machine Operator Panels series. It acts as the front end of an automation cell, giving operators direct access to axis data, NC programs, and diagnostics without opening the control cabinet. This arrangement lets routine interaction take place at the panel instead of through the main control hardware. As part of a complete drive and control platform, the panel supports routine adjustments, recipe changes, and alarm acknowledgments in packaging, metal-cutting, or material-handling equipment.

The panel accepts a wide supply window of AC 115 to 230 V, 50 to 60 Hz, so it can be installed in regions that use either North American or European mains voltages without a transformer. Its front fascia contains 16 machine function keys, and each key can be mapped to a PLC bit for direct access to common commands such as cycle start, coolant on, or jog mode. Inside the enclosure, the electronics use 128 MB of SDRAM, which is sufficient for buffering part programs, position tables, and screen graphics without delaying the control task. A built-in Disk drive 3.5 inch, 1.44 MB provides removable primary storage for standard floppy disks. Operator data entry relies on a Standard keyboard layout, making text editing and parameter input familiar to users accustomed to a PC-style interface.

The enclosure follows Design 3, indicating the third hardware revision with updated EMI shielding and connector placement. Control logic is executed through the panel’s ISP function type, so an integrated screen processor can handle soft-PLC tasks locally instead of relying only on the host CNC. The model is classified under Product line 20 inside the wider BTV Panel family, so cabling and mounting cutouts match other 20-series stations.
