BTA20.3-NA-DK-BA-BS

The BTA20.3-NA-DK-BA-BS module from Bosch Rexroth Indramat is a core component of the BTA20 Machine Control Boards series, designed for robust industrial automation. This terminal block features a voltage rating of 300V and a current rating of 20A, supporting a broad spectrum of machine control tasks. The module’s screw clamp connection method ensures secure and maintenance-free wiring, while its polyamide 6.6 insulation delivers exceptional mechanical strength and electrical protection. Configured as NA-DK-BA, the board offers three distinct positions and seamless integration with INTERBUS-S / BT-BUS communication networks. Early integration into factory automation lines is facilitated by a compact DIN rail mounting footprint that minimizes panel space.

Performance characteristics of the BTA20.3-NA-DK-BA-BS emphasize reliability under demanding conditions. The operating temperature range of –40°C to +105°C guarantees consistent performance in extreme environments, from cold storage to foundry applications. Brass terminal material provides excellent conductivity and corrosion resistance, supporting repeated cable insertions without performance degradation. End plate compatibility allows for flexible expansion, adding or removing modules without interrupting the communication bus. Wide wire size compatibility (12–22 AWG) accommodates standard industrial wiring practices, while the board’s product designation ("BTA") aligns with Bosch Rexroth’s modular control architecture. Whether coordinating high-speed packaging lines or complex CNC machining centers, the board’s architecture ensures minimal signal latency and dependable current delivery.

Built for seamless system integration, the BTA20.3-NA-DK-BA-BS offers a high degree of reliability and ease of use. The compact design and standardized DIN rail mounting simplify enclosure layout and reduce installation time. Its terminal block type configuration is ideally suited for retrofits and new installations in sectors such as assembly automation, material handling, and process control. With protection against mechanical stress and robust temperature tolerance, the module maintains uninterrupted network connectivity and precise control signal distribution. Bosch Rexroth Indramat’s quality assurance protocols assure consistent performance over extended duty cycles in industrial automation environments.
