Brief Functions

• F3PU10

  Power supply for the FA‑M3 rack, 100–240 VAC input.
• F3SP28 (×2)

  High‑performance CPU for sequence control, high‑speed processing,

  suitable for mid‑to‑large FA‑M3 systems.
• F3SP20

  Standard CPU module, lower speed than SP28, for small‑to‑mid systems.
• F3WD64 (×2)

  32‑point DC input + 32‑point relay output hybrid module

  → used for field signals and driving relays/valves/indicators.
• F3BU06

  6‑slot backplane (base unit) where all modules mount.
• F3LC11

  RS‑422/RS‑485 communication module

  for connecting to PC, HMI, or other PLCs via MODBUS/PC Link.
