Explanation of the icons
	Depending on control points, total 256 I/O extension devices can be connected. *Includes CC-Link remote I/O
	FX3U/FX3UC can count at high speed input frequency 100kHz (1-phase 6pts), 50kHz (2-phase 2pts), 10kHz (1-phase 2pts).
	Depending on control points, total 384 I/O extension devices can be connected. *Includes CC-Link remote I/O
	FX3S/FX3GC has 2 axes simple positioning function built into the main unit.
	Depending on the purpose, various special function blocks can be connected.
	FX3G/FX3U/FX3UChas 3 axes simple positioning built into the main unit.  *FX3G 14 pt, 24 pt models have independent 2 axes.
	Function can be easily added by mounting a function expansion board to the main unit.
	I/O can be connected in connector format, reducing wiring effort.
	In FX3UC-32MT-LT, CC-Link/LT master functionality is built-in.
	1 phase: 60 kHz x 4 pts/ 10 kHz x 2 pts    2 phase: 30 kHz x 2 pts/ 5 kHz 1 pt
	1 phase: 60 kHz x 2 pts/ 10 kHz x 4 pts     2 phase: 30 kHz x 1 pt/ 5 kHz 1 pt
	In FX3S-30MR/ES-2AD, FX3S-30MT/ES-2AD, and FX3S-30MT/ESS-2AD, 2ch analog input (current input) function is built-in.

 

Main Unit

All-in-one power supply, CPU, and I/O main unit. Built-in features include high-speed counters and positioning outputs.

I/O Extension

Both [I/O Extension Units] with a built-in power supply and [I/O Extension Blocks] without a power supply are available in various I/O sizes and configurations.

Analog Control

Options for analog inputs and outputs, temperature sensor inputs, and temperature control are available.

High-Speed Counting

Options are available to increase the performance of the built-in high-speed counters or provide additional high-speed counting capacity.

Positioning Control
