Product Description:
The BTA20.2-NA-ZP-VA-BS is a machine control board produced by Bosch Rexroth Indramat and supplied within the BTA20 Machine Control Boards series. It provides centralized operator and safety functions for multi-axis cells by mounting directly in the front panel of a control cabinet and relaying field signals to the drive and PLC layers. The board is intended to simplify installation in industrial automation lines where organized wiring and integrated emergency-stop handling are required. Its panel-mounted layout also keeps operator controls and machine-status functions in one accessible location.
The unit communicates over INTERBUS-S / BT-BUS, and its backplane moves a 48-bit data word during each internal cycle, allowing status, command, and diagnostic information to be exchanged across as many as eight axes. A remote transmission speed of 500 Kbaud is supported, which matches common INTERBUS-S couplers and helps maintain reliable communication over extended machine sections. Local I/O includes 8 inputs and 8 outputs, so sensors, limit switches, and valve coils can be connected directly without additional interface hardware. The board occupies eight built-in positions inside the BTA rack, with separate locations reserved for process control, safety functions, and override tasks, while the first slot is fitted with an emergency-stop channel and the second contains the ZP basic module that distributes the internal bus.
The front panel is rated IP65 for exposed operator areas, while the rear housing is rated IP20 for protected cabinet installation where convection cooling is sufficient. The aluminum housing is 407 mm wide, 169 mm high, and 100 mm deep, and it fits a rectangular panel cutout measuring 376 mm by 137 mm. Slot 1 contains the Emergency-Stop Type NA module, and Slot 3 carries the VA feed-override module so the operator can reduce machine speed during setup. The exterior uses RAL 7035 gray, which matches the neutral finish commonly used across the Indramat control family.
