BTA20.3-NB-FP-VB-BS

The BTA20.3-NB-FP-VB-BS, Bosch Rexroth Indramat, BTA20 Machine Control Boards module is a precision machine control board engineered for advanced automation applications. It leverages an INTERBUS-S / BT-BUS communication bus and integrates an NB-type emergency stop module for direct BTC06 control-unit connectivity. The board also incorporates a VB feed module equipped with two gray code override switches for both spindle and feed adjustment. As part of the BTA20 series, it seamlessly mates with BTV20 series components to form a sophisticated, user-oriented control panel tailored for high-performance drive systems.

This control board features a 2.1 kg mass and operates reliably in ambient temperatures from 5 °C to 45 °C, with transport tolerances from –20 °C to 60 °C. Heat dissipation is limited to 10 W under nominal load, while the main housing maintains an IP20 rating and the front-module plate achieves IP65 ingress protection. Constructed of varnished aluminum coated with polyester foil and finished in light grey (RAL 7035), the front plate resists chemical exposure and industrial contaminants. The unit supports installation at altitudes up to 1500 m above sea level and functions across air pressures of 860 to 1060 hPa, ensuring stable performance in varied environments.

Engineered for seamless integration into drive cabinets, the BTA20.3-NB-FP-VB-BS control board enhances system reliability through robust ESD-protected interfaces and a safe operating design. Its compact form factor and modular configuration simplify maintenance and field upgrades, reducing downtime. Ideal for demanding industrial automation installations, this board delivers precision control, proven durability, and straightforward connectivity in critical machine-tool and production-line applications.
