BTA20.4-NA-PP-VE-BS
BTA20 Machine Control Boards
The Bosch Rexroth Indramat BTA20.4-NA-PP-VE-BS from the BTA20 Machine Control Boards series combines robust construction and precise control for demanding industrial automation tasks. This board features a compact 20 mm profile width and 20 mm profile height, forged from polypropylene with a tensile strength of 38 MPa and flame resistance rated at UL94 HB. Measuring 407 mm × 169 mm × 119 mm and weighing 2.1 kg, it serves as a reliable control interface for machine operation. The primary function of this control board is to manage emergency stop circuits, user inputs, and feed control signals via the INTERBUS communication bus, ensuring safe and responsive machine control in automated systems.
In technical operation, the BTA20.4-NA-PP-VE-BS requires a regulated 24 VDC ±20% power supply and draws up to 1 A, consuming 18 W under full load. The board integrates an emergency hard-wired stop pushbutton with status indicator lamp alongside 8 programmable switching buttons, and supports two redundant safety circuits for enhanced machine protection. The VE module provides 2 feed overrides via a 4-bit gray-code switch with up to 120% override level, transmitting signals on dedicated INTERBUS input addresses. Data communication is handled through RS-232/RS-422 auto-switching interfaces and INTERBUS I/O, supporting baud rates up to 38400.
Built for durability and efficiency, the control board housing is made of aluminum and wrapped in a chemical-resistant polyester foil, with an IP65-sealed front panel to guard against dust and water splashes. Its cutout dimensions of 375 mm W × 137 mm H × 119 mm D simplify panel integration, while the 8 isolated inputs/outputs and up to 90% RH humidity tolerance support versatile installation environments. The construction materials and temperature resistance of -20°C to +80°C ensure stable performance under fluctuating conditions. By adhering to industry standards such as UL94 HB and leveraging INTERBUS-S for seamless machine control, this board delivers enhanced safety, reliability, and precision for industrial automation applications.
