Product Description:
The BTA20.2-NB-FP-VB-BS control board is produced by Bosch Rexroth Indramat within the BTA20 Machine Control Boards series. It serves as a compact programmable node that supervises localized machine actions and feeds real-time I/O data to higher-level motion or CNC controllers in distributed automation systems. By integrating local discrete I/O, the board eliminates external terminal strips and simplifies cabinet wiring. INTERBUS-S and BT-BUS connectivity enable deterministic field communication, and two front override switches allow direct signal forcing from the panel when manual checking is required.
Sealing is divided between two zones. The front membrane, intended for exposed machine mounting, carries a sealing rating of IP65, which blocks dust ingress and water jets so status LEDs remain visible during washdown cycles. Behind the panel, the electronics sit in an enclosure rated IP20, which suits a protected cabinet interior and allows convection cooling. The board has a mounting footprint of 407 mm in width, 169 mm in height, and 100 mm in depth, permitting side-by-side stacking in crowded control racks. Communication to the master occurs over the INTERBUS-S / BT-BUS backplane, and a built-in converter translates RS232 service messages to the RS422/485 differential pair used by the network.
The logic section is powered from a stabilized rail of 24 V ±20%, so operation continues even when the supply drifts during machine startup. Each input is interpreted as high between 18–30 V and as low from 0–10 V, which removes the need for extra level shifters in typical control circuits. Process data are transferred in blocks three words long to match the controller addressing scheme used by the host system. The module provides opto-isolated inputs and sourcing outputs, and each output can deliver up to 200 mA while the combined load must remain below 800 mA. Opto-isolation helps separate field signals from the logic section during switching events.
