BTA20.3-NE-LP-KA-BS

The Bosch Rexroth Indramat BTA20.3-NE-LP-KA-BS is a robust machine control board in the BTA20 Machine Control Boards series designed for demanding industrial automation applications. This panel-mount device features a safety interlock switch type with a precision polyamide actuator material and lever-style actuator type for reliable engagement. Housed in a sturdy stainless steel body and encased in an IP67 enclosure rating shell, the board provides a high degree of protection against dust and immersion. It operates at a rated voltage of 250 VAC and a rated current of 10 A, while maintaining a low power footprint with 18 W power usage and 1 A maximum current consumption for control circuits. Advanced integration capabilities include the INTERBUS-S/BT-BUS communication bus for seamless network connectivity.

From a technical perspective, the BTA20.3-NE-LP-KA-BS offers a comprehensive suite of specifications tailored to industrial control environments. The front panel is manufactured from varnished aluminum combined with a chemical-resistant polyester foil, ensuring durability in corrosive settings. Electrical life is rated at 500,000 operations and mechanical life at 1,000,000 operations, reflecting long-term reliability under repeated cycling. The contact configuration comprises 1NO + 1NC contacts, supporting both normally open and normally closed safety functions. Cable entry is standardized to M20 x 1.5, simplifying installation and sealing. Its mounting type is a panel mount design, allowing straightforward integration into existing control cabinets.

Operational performance is defined by a wide ambient temperature range and robust switching capabilities. It functions reliably between +5 °C to +45 °C and survives storage or transit conditions from –25 °C to +70 °C. The device is rated to handle switching voltages up to 42 V AC and 24 V DC, while its input current remains below 10 mA and each output channel is limited to 200 mA. Its enclosure maintains an IP65 rating at the front panel for additional ingress protection, complementing the overall IP67 body rating. High-signal inputs operate between 18 to 30 V, enabling compatibility with common industrial PLC outputs. These operational features ensure high performance in assembly lines, packaging systems, and robotics where precise control and safety interlock compliance are critical.

Integration within broader automation systems is facilitated by standardized dimensions of 375 mm x 138 mm x 119 mm and a light gray (RAL 7035) finish that aligns with typical control cabinet aesthetics. The unit’s design designation is 3 with a configuration code of NE-LP-KA, allowing clear identification in spare parts and maintenance documentation. Communication interfaces include RS-232 IN, RS-422 IN, RS-422 OUT, as well as INTERBUS IN and OUT ports for distributed I/O architectures. The BTA20.3-NE-LP-KA-BS is ideally suited for industrial applications in manufacturing, material handling, and process automation where system uptime, safety interlocks, and environmental resilience are paramount.
