1 OVERVIEW
This User's Manual describes the specifications, handling and programming methods
for the Q64AD analog-digital conversion module (hereinafter referred to as the
Q64AD), Q68ADV analog-digital conversion module (hereinafter referred to as the
Q68ADV), and Q68ADI analog-digital conversion 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 conversion 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
µ
s/channel. Also, the
temperature drift compensation function can be performed using a processing
time of "conversion time for all ch 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 input range
Input range 1 change can easily be set using GPPW function software package
(hereinafter referred to as GPPW).
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.
(5) Easy settings using the utility package
A utility package is sold separately (SW0D5C-QADU-E).
The utility package is not a required item. However, it can be used to set initial
settings and automatic refresh settings on screen, reduce sequence programs,
and check settings and operating status.
