1 OVERVIEW
This user's manual explains the specifications, handling, programming methods and
others of Type AJ65SBT-62DA digital-analog converter module (hereafter abbreviated
to the "AJ65SBT-62DA") which is used as a remote device station of a CC-Link
system.
The AJ65SBT-62DA is a module designed to convert digital values (16-bit signed BIN
data) from outside the PLC into analog values (voltages or currents).
1.1 Features
This section gives the features of the AJ65SBT-62DA.
(1) High accuracy
This module performs D/A conversion at the accuracy of ±0.4% relative to the
maximum value of the analog output value at the operating ambient temperature
of 0 to 55°C, or at ±0.2% relative to the maximum value of the analog output
value at the operating ambient temperature of 25±5°C.
(2) Output range selectable per channel
You can choose the analog output range per channel to change the I/O
conversion characteristics.
(3) High resolution of 1/±4000
By changing the output range, you can choose and set the resolution to either
1/4000 or 1/±4000 (when the -10 to +10V range or user range setting 1 is
selected) to provide high-resolution analog values.
(4) Setting of analog output hold or clear at STOP of PLC CPU
You can specify whether to hold or clear the analog value which is being output
from each channel of the unit when the PLC CPU has entered the STOP mode
or the AJ65SBT-62DA has stopped D/A conversion due to error occurrence.
(5) Smaller than the conventional D/A converter module
This module is 60% smaller in installation area and 38% less in volume than the
conventional CC-Link D/A converter module (AJ65BT-64DAV/DAI).
(6) Up to 42 modules connectable
You can connect up to 42 AJ65SBT-62DA modules to one master station.
