Product Description:

The BTV20.3CA-28B-33C-S-FW is an operator panel manufactured by Bosch Rexroth Indramat and delivered as part of the BTV20 Machine Operator Panels series. Within the broader BTV Panel product family and product line 20, this unit functions as the local human-machine interface for CNC machinery and automated production cells. It combines a display area, a standard alphanumeric keyboard, and dedicated machine keys so an operator can issue motion commands, enter process data, and observe controller feedback without relying on an external computer.

The panel includes a minimum 3 GB HDD and a minimum 300 MHz CPU, giving the internal computer adequate nonvolatile capacity and processing speed for diagnostics, visualization, and boot files. Working memory is fixed at 128 MB RAM, which is sufficient for the real-time operating tasks assigned by Indramat controllers. Primary removable storage is provided through a Smart Card interface; this slot holds program backups or recipe data and can be removed without tools. The power section accepts a wide-range supply of AC 115 to 230 V, allowing the same panel to be installed on machines tied to either North American or European mains. Software is ordered separately so the panel can be matched to the project controller.

The front membrane carries 16 machine function keys that the OEM can map to spindle start, axis enable, coolant, or similar direct actions. All circuitry operates on line frequencies of 50 to 60 Hz, matching the voltage range stated earlier. The panel is classified by Bosch Rexroth as an MTC function type, meaning it supports Multi-Technology Control sequences rather than basic visualization only. Mechanical layout is identified as Design 3, a version that aligns the display, keyboard, and connector positions with current MPx and PPC controllers while keeping enclosure dimensions unchanged from earlier BTV20 units.
