Product Description:
The BTA20.4-NG-TP-VB-BS control board is produced by Bosch Rexroth Indramat and belongs to the BTA20 Machine Control Boards series. As a machine control board, it interfaces safety, communication, and input-output signals between the higher-level controller and the drive hardware in automated lines. The board provides fail-safe stop channels, serial links, and fieldbus connectivity so that motion axes and auxiliary devices can be supervised from a single central node. This arrangement allows control signals and protective functions to be handled in one location, which helps keep system coordination clear during normal machine operation.
Core processing capacity starts with a data path width of 48 bits, allowing simultaneous handling of multiple status flags and motion words. For shop-floor exposure, the varnished aluminum front panel is sealed to IP65, preventing dust ingress and resistance to low-pressure water jets. Interbus communication is sent at 500 kbaud, matching the cycle times of standard Rexroth PLC networks. The complete board width is 407 mm, while its maximum height reaches 169 mm, dimensions that should be considered when allocating rack space. One RS-232 input, one RS-422 input, and a dedicated RS-422 output are positioned at the lower edge to keep service wiring separate from field communication lines and to support orderly cable routing inside the enclosure.
Depth is limited to 119 mm, so the module fits into shallow enclosures while still leaving room for airflow behind the backplane. Eight discrete inputs rated for external 24 V logic are provided, and the board includes 8 external 24 V inputs for machine status and command signals. Three independent enabling lines are integrated, and 3 enabling circuits allow separate sections of the machine to be released in a controlled way. Machine safety is further supported by 2 E-stop circuits that interrupt drive power when either channel opens. A mounting height of 137 mm and a mounting width of 375 mm establish the hole pattern for panel installation, and the available inputs and outputs support direct connection to sensors, indicators, and interlock devices used throughout the machine.
