1. Introduction

The FX

-1DA-BD analog output expansion board (hereafter called “1DA” or “expansion board”) is to be

installed in an FX

or FX

series PLC, to increase the analog output by 1 point.

1.1 Features of 1DA

1) Analog output of 1 point can be increased using 1DA. If a 1DA is used, internal mounting in the top of

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

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

switching a dedicated special auxiliary relay.

Moreover, the digital value for conversion is stored in a dedicated special data register, as shown in

the table below.

However, the digital to analog conversion characteristics 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 board. (They will not function)

• The 1DA cannot be used together with a FX

-EEPROM-8L or FX

-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

2.3 Performance Specifications

*1 The D/A conversion is started following the END statement and analogue signals will be sent after

10ms. Further analogue signals will be sent after the D/A conversion triggered by the next END

statement. Converting the present value stored in D8114 is dependent on PLC scan time.

Note:

1) When external load resistance is 2k

Ω

, the overall accuracy of voltage output is adjusted

“±1%”

If external load becomes larger than 2k

Ω

, the output voltage will increase slightly. When

the load is 1M

Ω

, the output voltage becomes about 3% higher than the correct value.

2) When using current output, be sure to have an external load resistance of 500

Ω

or less.

If the load is greater than 500

Ω

, the output current will be lower than the correct value.

3. Installation

Caution:

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

on the expansion board 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 fixing 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

series PLC. Do not try

to install two or more expansion boards.

Moreover, the 1DA cannot be used with the FX

-EEPROM-8L or FX

-5DM.

The following is a generic explanation of how to install an 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 and 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
