[DESIGN PRECAUTION]
WARNING
Do not write data into "System area" of the buffer memory of intelligent function modules. Also,
do not use any "Use prohibited" signals as an output signal to an intelligent function module
from the programmable controller CPU.
Writing data into "System area" or outputting a signal for "Use prohibited" 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 or more from each other.
Not doing so could result in noise that may cause malfunction.
WARNING
CAUTION

A-2 A-2
[SECURITY PRECAUTIONS]
WARNING
To maintain the security (confidentiality, integrity, and availability) of the programmable controller
and the system against unauthorized access, denial-of-service (DoS) attacks, computer viruses,
and other cyberattacks from external devices via the network, take appropriate measures such
as firewalls, virtual private networks (VPNs), and antivirus solutions.
[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.

A-3 A-3
[WIRING PRECAUTIONS]
WARNING
After wiring, attach the included terminal cover to the module before turning it on for operation.
Failure to do so may result in electric shock.
CAUTION
Individually ground the FG terminal of the programmable controller with a ground resistance of
100or less.
Failure to do so may result in electric shock or malfunction.
Use applicable solderless terminals and tighten them within the specified torque range. If any
spade solderless terminal is used, it may be disconnected when a terminal screw comes loose,
resulting in failure.
Tighten the terminal screws within the specified torque range.
Undertightening can cause short circuit, fire, or malfunction.
Overtightening can damage the screw and/or module, resulting in drop, short circuit, or
malfunction.
Be careful not to let foreign matter such as sawdust or wire chips get inside the module.
They may cause fires, failure or malfunction.
The top surface of the module is covered with protective film to prevent foreign objects such as
cable offcuts from entering the module when wiring.
Do not remove this film until the wiring is complete.
Before operating the system, be sure to remove the film to provide adequate ventilation.

A-4 A-4
[STARTING AND MAINTENANCE PRECAUTIONS]
WARNING
Do not touch any terminal while power is on.
Doing so will cause electric shock or malfunction.
Shut off the external power supply (all phases) used in the system before cleaning the module or
retightening the terminal screws or module fixing screws.
Failure to do so may result in electric shock or cause the module to fail or malfunction.
Undertightening can cause drop of the screw, short circuit, or malfunction.
Overtightening can damage the screw and/or module, resulting in drop, short circuit, or
malfunction.
CAUTION
Do not disassemble or modify the modules.
Doing so may cause failure, malfunction, injury, or a fire.
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 failure or malfunction of 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 install/remove the module to/from the base unit, or the terminal block to/from the module
more than 50 times after the first use of the product. (IEC 61131-2 compliant)

1 OVERVIEW
This User's Manual describes the specifications, handling and programming methods
for the Q64AD analog-digital converter module (hereinafter referred to as the Q64AD),
Q68ADV analog-digital converter module (hereinafter referred to as the Q68ADV), and
Q68ADI analog-digital converter module (hereinafter referred to as the Q68ADI), which
are used in conjunction with MELSEC-Q Series CPUs.
In this manual, the Q64AD, Q68ADV, and Q68ADI are collectively referred to as the
A/D converter modules.
1.1 Features
(1) Select the type of module according to the application.
• Q64AD ........... 4 channels, where the voltage input or current input can be
selected for each channel.
• Q68ADV ........ 8 channels, all of which are voltage input.
• Q68ADI .......... 8 channels, all of which are current input.
(2) High speed conversion
Conversion is performed at a high speed of 80 s/channel. Also, the
temperature drift compensation function can be performed using a processing
time of "conversion time for all channels + 160 s".
(3) High degree of accuracy
The degree of accuracy for the conversion process is ± 0.1% (When the ambient
temperature is 25 ± 5 °C).
(4) Changing the resolution mode
The resolution mode can be changed according to the application, and digital-
value resolution settings of 1/4000, 1/12000 or 1/16000 can be selected.
(5) Changing the input range
The input range 1can easily be set from 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.
(6) Easy settings with GX Configurator-AD
The number of sequence programs can be reduced since GX Configurator-AD
(sold separately) allows A/D converter module settings in the dialog box.
Also, GX Configurator-AD simplifies checking of the module settings and
operation status.
In addition, FB 1 can be automatically created from intelligent function module
parameters set in advance to use them 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 details of FB, refer to "GX Developer Version 8 Operating Manual (Function
Block)."
