BTA20.3-NA-WK-BA-BS
BTA20 Machine Control Boards
The BTA20.3-NA-WK-BA-BS from Bosch Rexroth Indramat is a precision-engineered module in the BTA20 Machine Control Boards series, combining robust design with versatile functionality. It is rated for 20 A rated current at a 600 V rated voltage, and mounts securely on DIN rails via its DIN Rail Mount design. The board features a polyamide housing with brass, tin-plated Contact Material, ensuring corrosion resistance in demanding environments. With a compact footprint and standardized Configuration NA-WK-BA, it integrates seamlessly into industrial automation racks.
Built for high-performance connectivity, this control board offers one RS422 IN and one RS422 OUT channel alongside dedicated INTERBUS IN and INTERBUS OUT ports. Communication is handled via the INTERBUS-S / BT-BUS, supporting synchronized data exchange across distributed systems. The unit accommodates wire sizes from 22-12 AWG with secure Screw Clamp termination, and its Number Of Poles 3 configuration ensures reliable input/output isolation.
Engineered for durability, the board withstands temperatures from -40°C to +105°C, while maintaining an Insulation Resistance ≥ 10^9 Ω to protect against transient surges. A precisely tuned Torque 0.5–0.6 Nm on its clamp screws guarantees consistent electrical contact over extended duty cycles. Whether used for emergency stop circuits or switching between 24 V DC and 42 V AC control lines, this module delivers dependable performance in the most challenging industrial settings.
