OVERVIEW

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.

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.
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
High degree of accuracy
The degree of accuracy for the conversion process is ± 0.1% (When the ambient
temperature is 25 ± 5 °C).
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.

The input range can 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.
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 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)."
