USER’S GUIDE
JY992D74901C
This manual contains text, diagrams and explanations which will guide the reader in the correct installation
and operation of the FX
2N
-2DA special function block and should be read and understood before
attempting to install or use the unit.
Further information can be found in the FX SERIES PROGRAMMING MANUAL,FX
2N
SERIES
HARDWARE MANUAL of each PLC.
1. INTRODUCTION
The FX
2N
-2DA type analog output block (Hereafter referred to as the FX
2N
-2DA) is used to convert a
digital value of 12 bits into an analog output of two points (voltage output and current output), and to
forward the values to the Programmable controller (Hereafter referred to as a PLC).
FX
2N
-2DA can be connected with FX
0N
, FX
1N
, FX
2N
, and the FX
2NC
series Programmable controllers.
1) The analog out put is selected from the voltage output or the current output by the method of
connecting wires.
At this time, assume setting to be two channels common analog output.
2) The two analog output channels can accept output of 0 to 10V DC, 0 to 5V DC, or 4 to 20mA.
(The mixture use for the voltage output/the current output is possible.)
3) Resolution is 2.5mV (0 to 10V DC) and 4
µ
A(4 to 20mA).
4) The digital to analog conversion characteristics can be adjusted.
5) The block occupies 8 I/O points which can be allocated from either inputs or outputs.
6) The data transfer with the PLC uses the FROM/TO instruction.

4. CONNECTION WITH PROGRAMMABLE CONTROLLER
1) Up to 4 FX
2N
-2DA units can be connected to an FX
0N
series PLC, up to 5 for FX
1N,
up to 8 for FX
2N
or,
up to 4 for an FX
2NC
series PLC, all with powered extension units.
However the following limitation exists when undermentioned special function blocks are connected.
FX
2N
: Main unit and powered extension units of 32 points I/O or less. Consumption current available for
undermentioned special function blocks
≤
190mA
FX
2N
: Main unit and powered extension units of I/O 48 points or more. Consumption current available
for undermentioned special function blocks
≤
300mA
FX
2NC
: Up to 4 undermentioned special function blocks can be connected regardless of the system I/O.
FX
0N/1N
:Main unit and powered extension units. Up to 2 undermentioned special function blocks can be
connected regardless of the system I/O.
The consumption of the above units is to be subtracted from the service power supply of the host
PLC.
2) The blocks occupy 8 points (The 8 points can be allocated from either inputs or outputs).
3) FX
2N
-2DA consumes 5V DC 30mA.
The total of 5V consumption of all special function blocks connected to an FX
2N
or FX
2NC
main unit or
an FX
2N
extension unit must not exceed the 5V source capacity of the system.
4) The FX
2N
-2DA and main unit are connected by a cable on the right of the main unit.
5. SPECIFICATIONS

The D/A data is written in the binary in order of subordinate position 8bit and high rank
4bit,divided into two portions.
BFM#17:b0•••The D/A conversion of CH2 begins by changing of 1
→
0.
b1•••The D/A conversion of CH1 begins by changing of 1
→
0.
b2•••The subordinate position eight bit data for the D/A conversion is held by changing of 1
→
0.
Write data in above-mentioned buffer memory by "8.Program example".

Range of analog output
At shipping, the unit is adjusted to a digital range of 0 to 4000 for an analog
voltage output of 0 to 10V DC. When using FX
2N
-2DA by the current input or
the 0 to 5V DC output, it is necessary to readjust by the offset and gain
volumes.

Only subordinate position 12bit becomes effective when the data of 13bit or
more is input, and high rank bit any more is disregarded.
Use a digital value within the range from 0 to 4095.
The output characteristic can be set to each two channels.
