[DESIGN PRECAUTION]

!

DANGER

• Do not write data into the "system area" of the buffer memory of intelligent function modules.
Also, do not use any "prohibited to use" signals as an output signal to an intelligent function
module from the PLC CPU.
Writing data into the "system area" or outputting a signal for "prohibited to use" may cause a
PLC system malfunction.

!

CAUTION

• Do not bunch the control wires or communication cables with the main circuit or power wires, or
install them close to each other.
They should be installed 100mm(3.9inch) or more from each other.

1 OVERVIEW

1 OVERVIEW

This User's Manual describes the specifications, handling and programming methods
for the type Q64A D -GH cha nn el isola t ed high re so lution analog-digital converter
module (hereinafter referred to as the Q64AD-GH) and type Q62AD-DGH channel
isolated high resol ut io n an al og -dig it al conv e rte r modu le (w ith sign al cond it io nin g
function) (hereinafter referred to as the Q62AD-DGH), which are used with the
MELSEC-Q series CPU modules.
The Q62AD-DGH is exclusively used for current input.
In this manual, the Q64AD-GH and Q62AD-DGH are collectively referred to as the A/D
converter modules.

1.1 Features
(1) Channel isolated

The channels are isolated.
The Q62AD-DGH is also isolated between the external supply power and
channels.

(2) High resolution

The resolution is as high as 32-bit signed binary (data part is 16 bits long). (When
the -10V to +10V range is selected)

(3) Power supply to 2-wire tr ansmitter ( Q62AD- D GH only)

Supplying power to the 2-wire transmitter, the Q62AD-DGH does not require the
power supply for the 2-wire transmitter.
Supply power can be switched ON/OFF channel-by-channel by the A/D
conversion enable/disable setting.

(4) Module protection provided by shor t-circ uit pr otecti on cir cui t

(Q62AD-DGH only)

If an excessive current flows into the module due to a short circuit of the wiring,
the short-circuit protection circuit limits the current to within 25 to 35mA,
protecting the module.

(5) Analog input check by check terminals (Q62AD-D GH only)

Measurement of a voltage at the check terminals allows the mA of the 2-wire
transmitter output to be checked without the wiring being disconnected.

(6) High accuracy

The reference accuracy 1 is as high as ±0.05% and the temperature coefficient

2

is as high as ±71. 4pp m/°C .

1 Accuracy of offset/gain setting at ambient temperature
2 Accuracy per temperature change of 1°C

Example) Accuracy when the temperature varies from 25°C to 30°C

0.05% (reference accuracy) + 0.00714%/°C (temperature
coefficient)

5°C (temperatu re va ri a tio n di ffe re n ce ) = 0. 0 857%

The input range 3 ca n ea sily be set fro m th e GX De vel o pe r.

3 Input range refers to the type of offset/gain settings. The most frequently

used range is set as the default but the user can also set the offset/gain.

(8) A/D conversion system

There are the following five A/D conversion systems.
(a) Sampling processing

Analog input values are converted into digital values one by one on a
channel basis and the digital output value is output at every conversion.

(b) Averaging processing

1) Time averaging
A/D conversion is averaged in terms of time on a channel basis and a
digital average value is output.

2) Count averaging
A/D conversion is averaged in terms of count on a channel basis and a
digital average value is output.

3) Move averaging
The specified number of digital output values measured per sampling
time are averaged .

(c) Primary delay filter

A digital output value is smoothed according to the preset time constant.

(9) Input signal error detection function

The voltage/cur ren t out sid e th e set ting ra nge is detected.

(10) Warning output

There are the following two warning outputs.
(a) Process alarm

A warning is output if a digital output value falls outside the setting range.

(b) Rate alarm

A warning is output if the varying rate of a digital output value falls outside
the preset varying rate range.

(11) Online module change

The module can be changed without the system being stopped.
Further, the dedicated instruction (G. OGLOAD, G. OGSTOR), write to the buffer
memory, or turning ON the Y signal enables "inheritance of offset/gain settings to
the new A/D conve rt er mod ule repl a ci ng th e old one changed online" and
"transfer of offset/gain settings to the other A/D converter module mounted on the
other slot". (These apply to the modules of the same model.)

1 OVERVIEW

(12) Offset/gain setting

GX Configurator-AD, dedicated instruction (G. OFFGAN) or mode switching
setting allows a shift to the offset/gain setting mode easily.

(13) Easy settings using the utility package

A utility package is sold separately (GX Configurator-AD).
The utility package is not a required item, however, it is useful for on-screen
setting of the intelligent function module parameters (initial setting/auto refresh
setting). In addition, FB

can be generated au to matically from the intelligent

function module parameters that have been set up and used in a sequence
program.

1: FB is the function for making a circuit block used in a sequence program

repeatedly a part (FB) to use it in the sequence program.
This function can improve the efficiency of program development and
minimize program bugs to improve program qualities.

For the details of FB, refer to "GX Developer Version 8 Operating Manual
(Function Block)."

3.1.2 I/O conversion characteristic

The I/O conversion characteristic represents the angle formed by a straight line
connecting the "offset value" and "gain value" when the analog signals (voltage or
current input) from outside the PLC are converted to digital values.

Offset value

The offset value denotes the analog input value (voltage or current) that makes the
digital output value 0.

Gain value

The gain value denotes the analog input value (voltage or current) that makes the
digital output value:
