1. Introduction

The FX

-2AD-BD analog input expansion board (hereafter called “2AD” or “expansion board”) is to be

installed in an FX

or FX

series PLC, to increase the analog input by 2 points.

1.1 Features of 2AD

1) Analog input of two points can be increased using 2AD. If a 2AD is used, internal mounting in the top

of the PLC means that there is no need for a change to the installation area of the PLC.

2) Voltage input (0 ~10V) or current input (4 ~ 20mA) for analog to digital conversion can be set by

switching the auxiliary relays assigned to each channel.

Moreover, a digital value after conversion of each channel is stored in special data register allocated

to each channel, as shown in the table below.

However, the analog to digital conversion characteristic cannot be adjusted.

1.2 External Dimensions and Each Part Name

a) Terminals to connect analog module

The top face of this terminal block is higher than the top face of the

panel cover of the programmable controller by approximately 7mm

(0.28").

b) Mounting holes (2-

∅

4.0 / 0.16")

c) Connector for PLC

1.3 System Configuration

• Only one expansion board can be used on one FX

and FX

PLC main unit.

Do not try to install two or more expansion boards. (They will not function)

• The 2AD cannot be used with a FX

-EEPROM-8L or FX

-5DM.

3. Installation

Caution:

• Cut off all phases of power source before installing / removing or performing wiring work

on the master in order to avoid electric shock or damage of product.

• After the installation and wiring etc. replace the PLCs top cover before power ON.

Note:

• Securely install the expansion board, and fix to the PLC. Defective contact can cause

malfunction.

• The tightening torque for fix the board or top cover is 0.3 ~

0.6

m. Tighten securely to

avoid malfunction.

Note:

Only one expansion board can be used per main unit of FX

and FX

PLC. Do not try to

install two or more expansion boards.

Moreover, the 2AD cannot be used with the FX

-EEPROM-8L or the FX

-5DM.

The following is a generic explanation of how to install a expansion board to

the PLC.

a) Top cover for expansion board

b) M3 self-tapping screw to mount expansion board

c) M3 self-tapping screw to fix top cover

d) External port for optional equipment

e) Expansion board

Note: Do not remove this screw.

1) Remove the top cover of the main unit an keep.

2) Plug expansion board “e)” into the external port “d)”.

3) Fix expansion board to main unit using M3 self-tapping screws “c)”. (Tightening torque: 0.3 ~ 0.6N

⋅

4) Attach top cover for expansion board “a)” removing section “a)’” to expose connector etc.

5) Secure top cover with M3 self-tapping screw “b)”. (Tightening torque: 0.3 ~ 0.6N
