ment cond
itions given in the
generalspecifications.
▶If operated in other
environment
not specified in the general
specifications, it can cause an
electric shock, a fire, malfunction
or damage or degradation of the
module
▶
Make sure the module fixing
projectio
ns is inserted into the
module fixing hole and fixed.
▶Improper installation of the mod-
ule can cause malfunction, dis-
order or falling.
CAUTION
!
WiringPrecautions
▶When grounding a FG terminal,
be sure to provide class 3
grounding which is dedicated to
the PLC.
▶Before the PLC wiring, be sure to
check the rated voltage and ter-
minal arrangement for the mod-
ule and observe them correctly.
If a different power, not of the
rated voltage, is applied or
wrong wiring is provided, it can
cause a fire or disorder of the
nodule.
▶Drive the terminal screws firmly
tothedefinedtorque.
If loosely driven, it can cause
short circuit, a fire or malfunc-
tion.
▶
Be care
ful that any foreign matter
like wire scraps should not enter
into the module.
It can cause a fire, disorder or
malfunction.

Chapter 1. INTRODUCTION
The G3F-DA4V, the G3F-DA4I and the G4F-DA1A are digital/analog conversion modules for use with the GLOFA
PLC GM 1/2/3/4 series CPU module and the MSTER-K300S/1000S series CPU module. The G4F-DA1A is used
on the GM4 series module and the K300S series module. the G3F-DA4V and the G3F-DA4I are used on the
GM1/2/3 series module and the K1000S series module. (Here-in-after the G4F-DA1A, G3F-DA4V and G3F-DA4I
are called the D/A conversion module)
The D/A conversion module is to convert a 16-bit, signed BIN digital value into an analogoutput signal (voltage or
current).
1.1 Features
1.1.1 G3F-DA4V / G3F-DA4I
1)Allows digital to Analog conversion for 16 channels per a module.
G3F-DA4V: 1 module can be performed for D/A conversion (voltage output) of 16 channels.
G3F-DA4I: 1 module can be performed for D/A conversion (current output) of 16 channels.
2) High resolution of 1/16000
A digital value resolution can be selected among 1/16000 and so the analog value of high resolution
iskept.
4)The number of the D/A conversion module mounted on one base is unlimited.
On use of power supply module of the G3F-PA1A or G3F-PA2A, the G3F-DA4V and G3F-DA4I can
be mounted up to 4.

1.2 Glossary
1.2.1 A-Analog Value
Analog value is a sequentially changing value such as voltage, current, temperature, speed, pressure,
flux, etc.
Temperature, for example, is sequentially changing according to the time. Because this temperature is
not input on the PLC directly, the same analog value of DC voltage (0 to ±10V) or current (4 to 20mA)
inaccordance with the temperature should be input on the PLC through transducer.
1.2.2 D-Digital Value
Digital value is non-sequentially changing value written
as the number like 0, 1, 2, 3. The signal of on or off is
written as digital value of 0 or 1. There are BCD value
and binary value in the range of digital value.
Analog value isn't written directly on the CPU. For
analog input to the CPU operation, analog converted
to digital value has to be input on the CPU. and for
analog output, the digital of CPU should be
converted to analog.

2.5 Input/Output Conversion Characteristics
I/O characteristics are displayed as a slant of the line connecting offset value and gain value in converting an
digital signal from the external PLC into an analog signal(voltage or current).
The I/O conversion characteristics of the D/A conversion module are shown.
2.5.1 Offset/ Gain Value
1)Offset and gain value is as follows
a)Offsetvalue
Data formatof -8192～8191: When digital input value is -8000, offset value is analog output value.
Dataformatof -192～16191: When digital input value is 0, offset value is analog output value.
b)Gain value
Dataformatof -8192～8191: When digital input value is 0, offset value is analog output value.
Dataformatof -192～16191: When digital input value is 8000, offset value is analog outputvalue.
2)Factory set value of offset and gain value is like table 2.4.
Module name Analog input range Offset value Gain value
G3F-DA4I DC 4～20 mA DC4mA DC 12 mA
G3F-DA4V -10 ～10 VDC -10 VDC 0 VDC
G3F-DA1A -10 ～10 VDC -10 VDC 0 VDC

2.5.3 Relations between Offset/ Gain Value andAnalog Output
The resolution of D/A conversion module can be changed by changing offset/ gain value. At the change of
offset/ gain value, the below formula can calculate resolution of analog value and analog output value by
digitalinput value.
Gain value -Offsetvalue
Resolution =
8000
Gain value -Offsetvalue
Analog output = 5Digital input value ＋Offsetvalue
8000
Analog output = Resolution 5Digital input value 5Offsetvalue
Ex) Gain value : 0 VDC Offset value : -10 VDC Digital input value : 12000
0 –(-10)
Resolution = = 0.00125
8000
Analog output = 0.00125 512000 ＋(- 10) = 5(V)
Since maximum resolution of D/A conversion module is like values on table2.5, if digital input value increase
or decrease one at a time, analog output value may be different with a result of above formula
Product code Analog output range Maximum resolution
G3F-DA4I DC 4～20 mA 1μA
-10 ～10 VDC 1.25 mV
G3F-DA4V -5 ～5 VDC 0.625mV
DC 4～20 mA 1μA
G4F-DA1A -10 ～10 VDC 1.25 mV
