BTA20.3-NA-LF-VB-BS

The Bosch Rexroth Indramat BTA20.3-NA-LF-VB-BS is part of the BTA20 Machine Control Boards series and serves as a robust interface for industrial automation tasks. Designed to coordinate operator commands with system-level responses, it features a current rating of 20A, a voltage rating of 600V, and a surge current capacity of 200A. This control board functions as a central processing module that ensures precise task execution, streamlined feedback loops, and reliable performance in demanding automated environments.

This module employs snubberless triacs for output switching, efficiently handling both inductive and resistive AC loads while minimizing electrical noise and transient spikes. It is equipped with a voltage insulated tab to isolate active circuitry from its mounting surface and prevent unintended grounding or shorts. Additional technical specifications include a gate trigger current (Igt) of 35mA, a gate trigger voltage (Vgt) of 1.3V, and a holding current (Ih) of 50mA. The off-state leakage current (Idrm) is rated at 2µA and the on-state voltage (Vtm) at 1.55V, all backed by an isolation voltage of 2500Vrms. Communication is handled via the INTERBUS-S/BT-BUS protocol, enabling seamless integration with modern control networks.

Built for durability, the board uses through-hole mounting to provide strong mechanical and electrical connections that resist vibration and mechanical stress. It operates reliably across an operating temperature range of -40°C to +125°C, making it suitable for harsh thermal environments. The module is RoHS compliant and constructed with lead-free materials, supporting environmental and safety standards. With its compact footprint and intelligent processing capabilities, the BTA20.3-NA-LF-VB-BS delivers enhanced efficiency, consistent control accuracy, and long-term reliability for a wide range of industrial automation applications.
