Product Details:

REXROTH BTA20.3-NA-HP-VB-BS belongs to Indramat BTA20 series modular machine operator panel for System200 motion control platform. The suffix 20.3 stands for upgraded hardware revision, NA is the main base circuit board, HP is operating mode selector module, VB is electronic handwheel override module, BS represents INTERBUS-S fieldbus communication interface. It adopts flush panel mounting structure, front face IP65 protection grade, and each functional module is pluggable for separate replacement. This legacy operator panel is discontinued, available stock are refurbished spare units for CNC machine tools and automated tightening production lines.

This operator panel serves as local machine operation terminal for on-site manual intervention. It supports operating mode switching, spindle speed and feed rate override adjustment, manual jog movement by high-resolution handwheel, cycle start and stop control. All operation signals and handwheel pulse data are transmitted back to the Indramat main control rack through INTERBUS-S bus. Shielded bus cable reduces electromagnetic interference generated by servo drives and harsh workshop environment.

The front panel housing is made of impact-resistant industrial plastic with matte grey surface. The VB handwheel module integrates high-precision encoder for smooth jog positioning. The HP mode selector module provides stable multi-gear mode switching for automatic, semi-automatic and manual operation. Rated supply voltage is DC24V. The modular slot design allows maintenance to swap only the faulty module instead of the whole panel, lowering maintenance cost.

All units pass strict testing before shipment including bus communication test, handwheel pulse test, switch contact test and long-time stability aging test, to guarantee reliable performance under long-time multi-shift industrial operation.

It is widely used on CNC machining centers, grinding machines, automotive assembly jigs and metal forming equipment. Typical application scenarios include local manual machine operation, spare replacement for aging Indramat BTA20 System200 control systems and old machine tool electrical retrofit. Automation integrators select this Rexroth panel for its 20.3 hardware revision and stable INTERBUS-S bus communication.
