CHAPTER1 OVERVIEW

This user's manual provides the specifications, handling instructions, programming
procedures, and other information of the Q64AD2DA analog input/output module
(hereinafter the "Q64AD2DA"), which is designed to use with the MELSEC-Q series CPU
module.
1.1

Features

(1) Analog input and output using a module
(2) Ranges can be set for each channel
(3) Switching resolution mode
(4) Scaling function
(5) Shifting function
(6) Input range extended mode function
The Q64AD2DA can perform both A/D conversion using four channels and D/A
conversion using two channels.
Various voltage or current range can be set for each channel.
Also, the ranges can be switched by using GX Developer.
* 1 Set in Switch setting for I/O and intelligent function module dialog box.
A resolution can be selected from a normal resolution mode (1/4000) and high
resolution mode (1/12000 or 1/16000).
* 2 Set in Switch setting for I/O and intelligent function module dialog box.
Digital output values can be converted to scaling values (ratio (%)) and the converted
values can be stored into buffer memory.
In D/A conversion, an input range of digital input values can be changed to a setting
range and the analog output can be performed.
In A/D conversion, a given value is added to an A/D converted digital output value.
In D/A conversion, a given value is added to a digital input value and an analog value
is output.
Changing a shifting quantity reflects the output value in real time. Therefore, the
output value can be adjusted with the shifting function when the CPU is powered on.
The analog input range, 4 to 20mA and 1 to 5V can be increased to the input range of
0 to 22mA and 0 to 5.5V, respectively.
A/D conversion can be performed even if the input range falls below 4mA or 1V, when
sensors do not measure concrete values.
Combining the input range extended mode function and input signal error detection
function detects a disconnection.
* 3 Set in Switch setting for I/O and intelligent function module dialog box.
