The BL234 EdgePLC series is an industrial edge controller designed for the convergence of real-time control and edge computing. As industrial automation evolves toward “Control + Edge Intelligence,” traditional PLCs often lack computing capability, while industrial PCs struggle with deterministic real-time control.
High-performance ARM-based edge controller merging real-time control and edge computing. Supports up to 32 N‑series I/O modules, multiple PLC runtimes, and rich industrial protocols for smart manufacturing and energy systems.
