The A02B‑0338‑B502 system controller is a versatile Fanuc CNC controller module that supports several Fanuc platforms such as Series 21i‑MB, Oi‑TD, Oi‑MD, and Oi‑TF. It is engineered as a central control unit that integrates the main CPU, memory, and communication interfaces, enabling smooth coordination of CNC motion, HMI, and I/O logic in industrial machine‑control systems.
This Fanuc CNC system controller typically features a 10.4‑inch TFT‑LCD color display with an iHMI‑style interface, providing an intuitive environment for G‑Code programming, diagnostics, and machine operation. It supports Ethernet, USB, and RS232 communication for program transfer, backup, and remote monitoring, and is compatible with Fanuc drives and I/O modules via standard FSSB and I/O‑Link‑style interfaces. The controller is suitable for CNC lathes, milling machines, and robotics‑integrated systems that require a compact, high‑performance control brain.
Physically, the A02B‑0338‑B502 system host is built as a compact, panel‑mountable industrial unit with a low‑profile housing suitable for dense CNC cabinets. It is manufactured in Japan and typically supplied as a 100% tested or refurbished module with a 12‑month warranty for new and 3‑month for used units. With fast delivery and broad compatibility across multiple Fanuc series, this Fanuc CNC system controller is an excellent choice for control‑rebuild projects, retrofits, and OEM automation setups involving 21i‑MB, Oi‑TD, Oi‑MD, or Oi‑TF‑based machines.
