• SAFETY PRECAUTIONS •

(Read these precautions before using this product.)
WARNING
CAUTION
Under some circumstances, failure to observe the precautions given under " serious consequences. Observe the precautions of both levels because they are important for personal and system safety. Make sure that the end users read this manual and then keep the manual in a safe place for future reference.
Indicates that incorrect handling may cause hazardous conditions, resulting in death or severe injury.
Indicates that incorrect handling may cause hazardous conditions, resulting in minor or moderate injury or property damage.
[Design Precautions]
WARNING" and " CAUTION".
CAUTION" may lead to
WARNING
• Install a safety circuit external to the programmable controller that keeps the entire system safe
even when there are problems with the external power supply or the programmable controller. Otherwise, trouble could result from erroneous output or erroneous operation. (1) The status of analog output changes depending on the setting of various functions that
control the analog output. Take sufficient caution when setting for those functions. For details of analog output status, refer to Section 3.4.5 ”Combinations of various functions”
(2) Normal output may not be obtained due to malfunctions of output elements or the internal
circuits. So build an external monitoring circuit that will monitor any single outputs that could cause serious trouble.
!
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(3.94inch) or more from each other. Not doing so could result in noise that would cause erroneous operation.
• At power ON/OFF, voltage or current may instantaneously be output from the output terminal of
this module. In such case, wait until the analog output becomes stable to start controlling the external device.
A - 1
[Installation Precautions]
!
CAUTION
• Use the module in the environment given in the general specifications of this Manual.
Using this programmable controller in an environment outside the range of the general specifications could result in electric shock, fire, erroneous operation, and damage to or deterioration of the product.
• For protection of the switches, do not remove the cushioning material before installation.
• Securely fix the module with a DIN rail or mounting screws. Tighten the screws within the
specified torque range. 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.
• Do not directly touch the module's conductive parts or electronic components.
Touching the conductive parts could cause an operation failure or give damage to the module.
[Wiring Precautions]
!
CAUTION
Shut off the external power suppy for the system in all phases before wiring.
Failure to do so may result in damage to the product.
• Be sure to ground the FG terminals to the protective ground conductor. Not doing so could result
in erroneous operation.
Use applicable solderless terminals and tighten them with the specified torque. If any solderless
spade terminal is used, it may be disconnected when the terminal screw comes loose, resulting in failure.
• When wiring in the programmable controller, be sure that it is done correctly by checking the
product's rated voltage and the terminal layout. Connecting a power supply that is different from the rating or incorrectly wiring the product could result in fire or damage.
• Tighten the terminal screws with the specified torque.
If the terminal screws are loose, it could result in short circuits, fire, or erroneous operation. Overtightening can damage the screw and/or module, resulting in drop, short circuit, or malfunction.
• Be sure there are no foreign substances such as sawdust or wiring debris inside the module.
Such debris could cause fires, damage, or erroneous operation.
• Do not install the control lines together with the communication cables, or bring them close to
each other. Failure to do so may cause malfunctions due to noise.
• When connecting the communication and power supply cables to the module, always run them
in conduits or clamp them. Not doing so can damage the module and cables due to loose, moved or accidentally pulled cables or can cause a malfunction due to a cable connection fault.
A - 2
[Wiring Precautions]
!
CAUTION
When disconnecting the communication and power supply cables from the module, do not hold
and pull the cable part. Disconnect the cables after loosening the screws in the portions connected to the module. Pulling the cables connected to the module can damage the module and cables or can cause a malfunction due to a cable connection fault.
[Starting and Maintenance Precautions]
!
CAUTION
• Do not touch the terminals while power is on. Doing so may cause malfunctioning.
• Be sure to shut off all phases of the external power supply used by the system before cleaning
or retightening the terminal screws. Not doing so can cause the module to fail or malfunction.
• Do not disassemble or modify the modules.
Doing so could cause trouble, erroneous operation, injury, or fire.
Do not drop or apply strong shock to the module. Doing so may damage the module.
Be sure to shut off all phases of the external power supply used by the system before mounting
or dismounting the module to or from the panel. Not doing so could result in damage to the product.
Do not install/remove the terminal block more than 50 times after the first use of the product.
(IEC 61131-2 compliant)
• Before touching the module, always touch grounded metal, etc. to discharge static electricity
from human body. Failure to do so can cause the module to fail or malfunction.
[Disposal Precautions]
!
CAUTION
• When disposing of this product, treat it as industrial waste.

1. OVERVIEW

1.1 Features

This user's manual describes the specification and handling of AJ65BT-64DAV digital analog voltage conversion module (abbreviated as AJ65BT-64DAV from here on) and AJ65BT-64DAI digital analog current conversion module (abbreviated as AJ65BT-64DAI from here on), which is used as the remote device station for the CC-Link system.
(1) AJ65BT-64DAV
This is a module which converts the digital values (16-bit encoded binary value) set in the programmable controller CPU to analog values (-10V to 0V to 10V voltage), and performs an external output to four channels.
(2) AJ65BT-64DAI
This is a module which converts the digital values (16-bit encoded binary value) set in the programmable controller CPU to analog values (4mA to 20mA current), and performs an external output to four channels.
In this manual, the name which refers to both AJ65BT-64DAV and AJ65BT-64DAI is abbreviated as “AJ65BT-64DAV/DAI.”
The AJ65BT-64DAV/DAI has the following features:
(1) One module can provide four channels of D/A conversion.
The AJ65BT-64DAV/DAI can produce output of analog values (voltage/current) to four external devices.
(2) The analog-output enable/prohibit setting is possible for each channel.
The sequence program can specify whether to enable or prohibit analog output to the external devices after the D/A conversion for each channel. Analog output from the channel where the analog output is prohibited will be 0V or 0mA.
(3) You can make the analog output hold/clear setting at a programmable controller CPU stop or link
error occurrence (all channels batch). Using the HOLD/CLR terminal, you can select whether to hold or clear the analog output at the instant the programmable controller CPU is set to a STOP status or a link error occurs.
(4) Offset and gain setting
When a fine I/O conversion characteristic is required, the offset and gain setting of each channel can be set without a volume control, enabling to modify the I/O conversion characteristic as desired.
