Product Details:

REXROTH BTA20.3-NC-DB-VB-BS belongs to Indramat BTA20 series modular machine operator panel for System200 motion control platform. The 20.3 marks the upgraded hardware revision, NC is the dedicated base mainboard variant, DB is membrane keyboard module, VB is high-resolution electronic handwheel module, BS stands for INTERBUS-S fieldbus communication interface. It adopts flush panel mounting, front face IP65 protection grade, and each functional module is pluggable for individual replacement. This legacy operator panel is discontinued, available stock are refurbished spare units for CNC machine tools and automated machining production lines.

This operator panel works as the local operation station for on-site machine operation. It supports manual jog movement via handwheel, spindle and feed override adjustment, program selection, parameter input and cycle start-stop control through DB keyboard module. All keyboard signals and handwheel pulse data are transmitted bidirectionally to the Indramat main control rack over INTERBUS-S bus. Shielded bus wiring reduces electromagnetic interference generated by servo drives and harsh workshop environment.

The front housing is made of impact-resistant industrial plastic. Long-life membrane keys on DB module support frequent input operation. The VB handwheel encoder delivers smooth and precise axis jogging for tool setting and workpiece alignment. Rated supply voltage is DC24V. The modular slot structure enables technicians to replace only the failed module instead of the complete panel for convenient maintenance.

All units pass factory inspection before shipment, including bus communication test, keyboard contact test, handwheel pulse test and long-time aging test, to guarantee stable performance under continuous multi-shift industrial production.

It is widely used on CNC machining centers, mold milling equipment, automotive machining fixtures and metal forming automation lines. Typical application scenarios include local CNC manual operation, spare replacement for aging Indramat BTA20 System200 control systems and old machine tool electrical cabinet retrofit. Automation integrators select this Rexroth panel for its NC base variant, keyboard plus handwheel combination and reliable INTERBUS-S communication.
