1. Introduction
The FX
1N
-2AD-BD analog input expansion board (hereafter called “2AD” or “expansion board”) is to be
installed in an FX
1S
or FX
1N
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.

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-

c) Connector for PLC
1.3 System Configuration
•
Only one expansion board can be used on one FX
1S
and FX
1N
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
1N
-EEPROM-8L or FX
1N
-5DM.

2.1 General Specifications
Same as the programmable controller main unit. (Refer to the programmable controller main unit manual)
2.2 Power Supply Specifications
Power supplied by internal feed of the programmable controller main unit.
2.3 Performance Specifications
*1 The A/D conversion is started following the END statement. A/D conversion of Channel 1 and 2 is
preformed in turn and not in simultaneous operation. Channel 1 conversion is completed in
approximately 15ms, however, at the End statement conversion of the present value stored in D8112
is dependent on PLC scan time. Channel 2 will start at the same time that Channel 1 completes the
refresh of D8112.
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 N
x
m. Tighten securely to
avoid malfunction.
Note:
Only one expansion board can be used per main unit of FX
1S
and FX
1N
PLC. Do not try to
install two or more expansion boards.
Moreover, the 2AD cannot be used with the FX
1N
-EEPROM-8L or the FX
1N
-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
