end user.
[DESIGN PRECAUTION]
!WARNING
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 programmable controller CPU.
Writing data into the "system area" or outputting a signal for "prohibited to use" may cause a
programmable controller 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.
Not doing so could result in noise that may cause malfunction.

[INSTALLATION PRECAUTIONS]
!CAUTION
Use the programmable controller in an environment that meets the general specifications
contained in the user's manual of the CPU module to use.
Using this programmable controller in an environment outside the range of the general
specifications may cause electric shock, fire, malfunction, and damage to or deterioration of the
product.
While pressing the installation lever located at the bottom of module, insert the module fixing tab
into the fixing hole in the base unit until it stops. Then, securely mount the module with the fixing
hole as a supporting point.
Improper installation may result in malfunction, breakdown or the module coming loose and
dropping.
Securely fix the module with screws if it is subject to vibration during use.
Tighten the screws within the range of specified torque.
If the screws are loose, it may cause the module to fallout, short circuits, or malfunction.
If the screws are tightened too much, it may cause damage to the screw and/or the module,
resulting in fallout, short circuits or malfunction.
Be sure to shut off all phases of the external power supply used by the system before mounting
or removing the module.
Not doing so may cause damage to the module.
In the system where a CPU module supporting the online module change is used and on the
MELSECNET/H remote I/O stations, modules can be replaced online (during energizing).
However, there are some restrictions on replaceable modules and the replacement procedures
are predetermined for each module.
For details, refer to the chapter of the online module change in this manual.
Do not directly touch the conductive area or electronic components of the module.
Doing so may cause malfunction or failure in the module.
[WIRING PRECAUTIONS]
!WARNING
After installation and wiring, attach the included terminal cover to the module before turning it on
for operation.

1 OVERVIEW
1 OVERVIEW
This User's Manual describes the specifications, handling and programming methods
for the type Q64AD-GH channel isolated high resolution analog-digital converter
module (hereinafter referred to as the Q64AD-GH) and type Q62AD-DGH channel
isolated high resolution analog-digital converter module (with signal conditioning
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 range -10 to 10V is selected)
(3) Power supply to 2-wire transmitter (Q62AD-DGH 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 short-circuit protection circuit
(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-DGH 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 1is as high as ±0.05% and the temperature coefficient 2
is as high as ±71.4ppm/°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 (temperature variation difference) = 0.0857%

1 OVERVIEW
(7) Changing the input range
The input range 1can easily be set from the GX Developer.
1: 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/current outside the setting range 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 replaced without stopping the system.
Using a sequence program further enables the following (limited to same model
pairs, though).
• Inheritance of offset/gain values to the A/D converter module after online module
change.
• Transfer of offset/gain values to a different A/D converter module mounted on
another slot.

1 OVERVIEW
(12) Offset/gain setting
GX Configurator-AD, dedicated instruction (G(P). OFFGAN) or mode switching
setting allows a shift to the offset/gain setting mode easily.
(13) Easy configuration with GX Configurator-AD
GX Configurator-AD, which is sold separately, allows the configuration of an A/D
converter module on its screen, thus resulting in a reduction of sequence
programs.
The setting status and operating status of the modules can be checked easily.
FB 1can be generated automatically from the intelligent function module
parameters that have been set up, and is available 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)."
