Hardware Specifications

Backplane Communication Velocity & Firmware Compatibility

The module integrates directly with the central processing backplane via high-speed communication channels, supporting deterministic network topologies. Firmware flash compatibility ensures seamless system updates without interrupting active control signals. Furthermore, backplane bus communication velocity guarantees rapid data transfer from the controller CPU, while I/O density scaling allows efficient system expansion across multiple modular nodes without sacrificing conversion precision.
