BTA20.3-NE-DC-BA-BS

The Bosch Rexroth Indramat BTA20.3-NE-DC-BA-BS control board delivers robust machine control functionality as part of the BTA20 Machine Control Boards series. Manufactured by Bosch Rexroth Indramat, this unit features a DC power supply and natural cooling for reliable operation in industrial environments. The board provides a rated output of 3.0 Nm and weighs just 7.3 kg, enabling straightforward installation and handling. Its enclosure meets IP54 ingress protection standards, ensuring resilience against dust and water spray while maintaining system uptime. A low noise profile of ≤65 dB further enhances suitability for factory floors and automated assembly lines.

The BTA20.3-NE-DC-BA-BS accepts a Power Supply of 18-30 V and draws a Max Power Consumption of 18 W with a Max Current Consumption of 1.0 A under full load. Its signal integration relies on Data 24 V inputs with a High Level range of 18-30 V, a Low Level range of 0-10 V, and an Input Current of 10 mA per channel. Output circuits deliver 200 mA per output, while the Enabling Circuit Switch Voltage Umax of 24 V DC / 42 V DC supports up to Enabling Circuit Switching Current Imax of 2 A DC / 3 A DC. The front panel offers enhanced protection with an IP65 rating, shielding internal electronics against contaminants. Communication is facilitated through the INTERBUS-S or BT-BUS protocols, ensuring seamless integration with higher-level controllers.

Operational performance is further optimized by the board’s natural convection cooling, which eliminates maintenance associated with fans and filters. Stable voltage regulation across the 18-30 V supply ensures consistent response to dynamic load changes, while the ENabling Circuit’s robust switching capacity supports inductive loads without degradation. Noise levels remain within ≤65 dB, minimizing interference in control cabinets. The interface handles rapid signal transitions and maintains data integrity, even under heavy switching conditions. Compact dimensions and a 7.3 kg mass contribute to reduced mechanical stress on mounting structures.

System integration is streamlined thanks to the BTA20.3-NE-DC-BA-BS’s compatibility with standard Bosch Rexroth Indramat control architectures. Its INTERBUS-S and BT-BUS connectivity allows direct communication with PLCs, motion controllers, and I/O networks. Ideal applications include CNC machine tools, automated assembly lines, packaging machinery, and process control installations where precise torque output and reliable signal management are critical. The board’s rugged design, combined with its array of electrical specifications, makes it an essential component for modern industrial automation solutions.
