Product details

The Mitsubishi FX3U-48MT/ESS is a MELSEC-F series main unit offering 24 digital inputs and 24 transistor source outputs, powered by 100–240 V AC. Program memory holds 64K steps (RAM, battery-backed). With a scan time of 65 ns for LD and 642 ns for MOV instructions, it handles mid-speed automation tasks. Local I/O expands to 256 points, total remote I/O up to 384. Outputs are sourcing (source logic): load connects between output terminal and common (0 V). The transistor type supports high-speed pulse output for positioning applications. RS-422 is standard; USB is optional (requires add-on module or adapter).

Frequently asked questions

Does the FX3U-48MT/ESS have a built-in USB port?

No, USB is listed as optional on this model. The standard onboard interface is RS-422. For USB programming, an optional adapter module is required.
