Product Details:

REXROTH BTA20.3-NC-DB-VD-BS belongs to Indramat BTA20 series modular machine operator panel for System200 motion control platform. The 20.3 represents upgraded hardware revision, NC is dedicated base mainboard variant, DB is membrane keyboard module, VD is electronic handwheel module, BS stands for INTERBUS-S fieldbus communication interface. It adopts flush panel mounting structure, front protection grade IP65, 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 machining automation lines.

This operator panel serves as local on-site operation terminal for machine operators. The DB membrane keyboard supports program selection, parameter input, function trigger and cycle control commands. The VD handwheel module provides high-resolution pulse output for manual axis jogging, tool setting and workpiece alignment. All keyboard signals and handwheel pulse data are transmitted bidirectionally to the Indramat main control rack through INTERBUS-S bus. Shielded bus wiring reduces electromagnetic interference generated by servo drives and harsh workshop environment.

The front panel shell is made of impact-resistant industrial plastic. The membrane keys feature long service life for frequent repeated operation. The VD handwheel has optimized internal encoder structure for smooth low-vibration jogging response. Rated supply voltage is DC24V. The modular slot design allows maintenance staff to replace only the faulty module instead of the whole panel, greatly cutting maintenance downtime and cost.

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

It is widely used on vertical and horizontal machining centers, mold milling machines, automotive fixture clamping stations and metal forming automation equipment. Typical application scenarios include local manual CNC 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, keyboard plus VD handwheel combination and reliable INTERBUS-S communication.
