BTA20.4-NA-BE-VB-BS

The Bosch Rexroth Indramat BTA20.4-NA-BE-VB-BS controller board represents a rugged and precise solution within the BTA20 Machine Control Boards series for industrial automation applications. Manufactured by Bosch Rexroth Indramat, this unit combines a ductile iron body with epoxy powder coated finish for enhanced corrosion resistance and mechanical durability. Offering a torque rating of 2000 Nm and a gear ratio of 20.4:1, it delivers robust power transmission and motion control. The enclosure features IP67 protection, safeguarding internal electronics against dust and water ingress. With support for any mounting orientation, the BTA20.4-NA-BE-VB-BS adapts easily to varied installation layouts.

The board’s mechanical and structural specifications ensure reliable operation under demanding conditions. The chassis is constructed from Ductile Iron and treated with Epoxy powder coated corrosion-resistant coating. It meets ISO 5211 flange standard specifications and integrates an ISO mounting output shaft with stainless steel construction for precise torque delivery. A visual Position Indicator provides real-time feedback on actuator position, while a standard Manual Override allows safe local operation during maintenance. The module’s physical dimensions of 407 × 169 × 119 mm (front panel) and 375 × 137 × 119 mm (mounting) support installation in compact control enclosures.

Operational performance is governed by stable electrical and environmental parameters. The BTA20.4-NA-BE-VB-BS accepts a Voltage Supply of 18 – 30 V DC with a maximum current consumption of approx. 1.0 A, limiting power draw to 18 W under peak load. It operates reliably across an Operating Temperature Range of -20 °C to +80 °C, and can be stored between -20 °C and +60 °C. The unit is designed for high-altitude installations up to 1500 m, withstanding air pressures from 860 to 1060 hPa. The integrated INTERBUS-S / BT-BUS communication bus supports distributed I/O networking with 48-bit data width for INTERBUS IN/OUT interfaces.

System integration is streamlined through compatibility with established Bosch Rexroth Indramat control architectures, facilitating direct connection to servo drives and HMI systems via the INTERBUS-S / BT-BUS interface. The controller’s Configuration NA-BE-VB enables flexible I/O mapping and diagnostic functions, while the series designation of Line 20, Design 4 identifies firmware feature sets for motion profile control. With robust ingress sealing and stainless steel output shafts, this board is particularly well-suited for demanding sectors such as packaging machinery, material handling systems, and heavy-duty process automation. Bosch Rexroth Indramat’s long-term reliability and precision control capabilities make the BTA20.4-NA-BE-VB-BS a core component in modern industrial machine designs.
