Extension units

Powered extension units are I/O extension devices with built-in power supply.

Like with the main unit, various I/O devices and special devices can be connected after a powered extension unit.

Regarding connection cable

A connection cable (length: 55mm), used to connect to the the right side of the device in front of the powered extension unit, is included with the powered extension unit.
To extend the distance of the connection, please use the optional "extension cable".

Function expansion board

The expansion board is designed to add the input and output terminal whose points are small to FX3S or FX3G PLCs. The board can be built in the PLC.

Model		Total number of points	Number of input/output points Input/output type				Applicable FX PLC
			Input		Output		FX 3S	FX 3G	FX 3U	FX 3GC	FX 3UC
	FX3G-4EX-BD	4 points	4 points	24 V DC (sink/ source)	-	-	*1 ○ Max. 1 unit	*2 ○ Max. 1 unit	×	×	×
	FX3G-2EYT-BD	2 points	-	-	2 points	Transistor (sink/ source)	*1 ○ Max. 1 unit	*2 ○ Max. 1 unit	×	×	×

*1: Supported by FX3S ver.1.10 and later.

*2: Supported by FX3G ver.2.20 and later.

Extension blocks

Extension block is an I/O extension device that receives power from the main unit or powered extension unit.

It can be connected in 8 point or 16 point units. The connectable number of points is determined by each main unit or powered extension unit

*1 :For connection to FX3GC or FX3UC, FX2NC-CNV-IF or FX3UC-1PS-5V is required.

*2 :Depending on the model name of the main unit, I/O extension device connection may or may not be allowed. For details, refer to the manual of the main unit.

Regarding connection cable

A connection cable, used to connect to the right side of the device in front of the extension block, is included with the extension block.

To extend the distance of the connection, please use the optional "extension cable (FX0N-30EC/FX0N-65EC)" and "connector conversion adapter (FX2N-CNV-BD)".

Extension block for connector type main unit (FX3GC, FX3UC)

These I/O extension devices can be directly connected to FX1NC, FX3GC, FX2NC, FX3UC PLCs.

They can be compactly extended because connection cables are not needed.
