PLC main unit for 80-point local I/O systems
The Mitsubishi FX3U-80MT/ESS is a MELSEC-F series main CPU unit with 40 integrated digital inputs and 40 transistor source outputs, all fed from a 100-240 VAC supply. Program memory is 64K steps in RAM with a 65 ns basic logic cycle, and the unit is expandable up to 384 total I/O points (local plus remote). The USB interface is listed as optional, so if you need USB programming, plan for a separate adapter module.
