BTA20.3-NA-ZP-BA-BS
BTA20 Machine Control Boards
The Bosch Rexroth Indramat BTA20.3-NA-ZP-BA-BS is a member of the BTA20 Machine Control Boards series designed for precision industrial automation. Manufactured by Bosch Rexroth Indramat, this board features a nominal diameter of 20 mm and a maximum working pressure of 1500 bar. Constructed from bright annealed steel with a zinc-plated finish, it delivers robust structural integrity. Its primary function is to serve as a compact, high-performance control module for machine tool operation and process automation in demanding industrial environments.
This control board offers comprehensive technical capabilities, including 8 addressable digital inputs and 8 outputs for flexible I/O communication via INTERBUS-S or BT-BUS fieldbus systems. Housed in a light grey RAL 7035 enclosure with overall dimensions of 407 x 169 x 100 mm, the module supports RS232 communication internally converted to RS422 or RS485. The device conforms to the NA-ZP-VA design format and accommodates three module slots for application-specific extensions. Weighing 3.2 kg, it integrates a nitrile rubber seal for enhanced environmental resistance and features a bolt set (BS) with a stroke of 10 mm and bolt length range of 45 6 2 6 mm.
Additional features include an operating temperature range from 209C to +2009C, air pressure tolerance of 860 to 1060 hPa, and nominal heat loss of about 10 W during continuous use. The front panel is IP65 rated with a chemically resistant polyester foil over lacquered aluminum, while the rear enclosure meets IP20 standards for cabinet installation. This board supports installation up to 1500 m altitude and offers durability through corrosion-resistant materials. In industrial applications, the BTA20.3-NA-ZP-BA-BS delivers reliable performance, seamless integration, and efficient control communication, improving uptime and precision in automated systems.
