Product Description:
The BTA20.2-NA-WH-VA-BS is a machine control board manufactured by Bosch Rexroth Indramat for the BTA20 Machine Control Boards series. It coordinates digital and analog signals between a CNC or PLC and field devices, allowing feed-rate adjustment and discrete I/O handling in automated machining centers, transfer lines, and similar production equipment. By combining network conversion and local override logic on one card, the board streamlines panel wiring, reduces the need for separate interface modules, and helps maintain consistent machine response in demanding industrial environments.
The board links to higher-level controls through the INTERBUS-S / BT-BUS fieldbus, and its local I/O section transfers data across three words with a total width of 48 bits. A built-in converter changes serial traffic from RS232 to RS422/485, so both legacy terminals and differential multi-drop links can use the same hardware. Remote segments operate at up to 500 kbaud, which supports the timing needed for coordinated data exchange between the control system and connected devices. The electronics are mounted on a card that stands 169 mm high, leaving room for status LEDs, address selection, and the Interbus ID code 3 selector within common 19-inch rack clearances. Eight external inputs and eight external outputs connect through pluggable terminal strips, which keeps channel access straightforward when several field connections are grouped on the same board.
The feed override potentiometer is digitized with 4-bit Gray code and limits spindle or axis feed to a maximum of 120%, allowing manual adjustment without permitting excessive speed increase. The light gray housing, finished in RAL 7035, uses a front plate sealed to IP65, while the card edges inside the cabinet remain at IP20. This separation suits front-facing exposure to dust or water spray while keeping the installed card appropriate for cabinet use. The overall footprint includes a width of 407 mm and a depth of 100 mm, so the board fits shallow enclosures while still leaving room for airflow behind the backplane and access to front-panel connections.
