• SAFETY PRECAUTIONS •

(Read these precautions before using.)

When using Mitsubishi equipment, thoroughly read this manual and the associated manuals introduced in
this manual. Also pay careful attention to safety and handle the module properly.
The precautions given in this manual are concerned with this product. Refer to the user's manual of the
CPU module to use for a description of the PLC system safety precautions.
These

SAFETY PRECAUTIONS classify the safety precautions into two categories: “DANGER” and

“CAUTION”.

DANGER

Procedures which may lead to a dangerous condition and cause death or serious
injury if not carried out properly.

CAUTION

Procedures which may lead to a dangerous condition and cause superficial to
medium injury, or physical damage only, if not carried out properly.

Depending on circumstances, procedures indicated by CAUTION may also be linked to serious
results.
In any case, it is important to follow the directions for usage.
Store this manual in a safe place so that you can take it out and read it whenever necessary. Always
forward it to the end user.

[DESIGN PRECAUTIONS]

!

DANGER

• Configure a safety circuit so that the safety of the overall system is maintained even when an
external power error or PLC error occurs.
Accident may occur due to output error or malfunctioning.
(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 functions in each
part”

(2) Normal output may not be obtained due to malfunctions of output elements or the internal

circuits. Configure a circuit to monitor signals which may lead to a serious accident

!

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(3.9inch) 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.

[INSTALLATION PRECAUTIONS]

!

CAUTION

• Use the module in the environment given in the general specifications of this Manual.
Using the module outside the range of the general specifications may result in electric shock,
fire or malfunctioning, or may damage or degrade the module.

• Securely fix the module with seated P-shape pan screws to the installation holes (two locations).
Improper installation may result in breakdowns or cause the module to fall out.

• Do not touch the conducted area of the module.
Doing so may cause module malfunctioning or breakdowns.

[WIRING PRECAUTIONS]

!

CAUTION

Be sure to shut off all phases of the external power supply used by the system before installation

or wiring.
Not doing so can cause the product to be damaged or malfunction.

• Always ground the FG terminal to the protective ground conductor.
Failure to ground these terminals may cause malfunctioning.

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 the module, check the rated voltage and terminal layout of the wiring, and make
sure the wiring is done correctly. Connecting a power supply that differs from the rated voltage
or wiring it incorrectly may cause fire or breakdown.

• Tighten the terminal screws with the specified torque. If the terminal screws are loose, it may
result in short circuits, fire or malfunctioning.

• Be careful not to let foreign matter such as filings or wire chips get inside the module. These can
cause fire, breakdowns and malfunctioning.

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.

• 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 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.

A - 3

[STARTING AND MAINTENANCE PRECAUTIONS]

!

CAUTION

• Do not touch the terminals while the 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.
Undertightening can cause a drop, short circuit or malfunction.
Overtightening can cause a drop, short circuit or malfunction due to damage of the screws or
module.

• Never disassemble or modify the module.
This may cause breakdowns, malfunctioning, injury and/or fire.

Do not drop the module or give it hard impact since its case is made of resin. Doing so can

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 can cause the module to fail or malfunction.

Do not install/remove the terminal block more than 50 times after the first use of the product.

(IEC 61131-2 compliant)

• Always make sure to touch the grounded metal to discharge the electricity charged in the body,
etc., before touching the module.
Failure to do so may cause a failure or malfunctions of the module.

[DISPOSABLE PRECAUTIONS]

CAUTION

• When disposing of this product, treat it as industrial waste.

Conformation to the EMC Directive and Low Voltage Instruction

When complying with EMC Directives and Low-Voltage Directives by assembling a
Mitsubishi PLC compatible with EMC Directive and Low-Voltage Directives into the
user product, refer to Chapter 3 "EMC Directives and Low-Voltage Directives" in the
User’s Manual (Hardware) for the CPU module being used.
The CE logo is printed on the rating plate on the main body of the PLC that conforms
to the EMC directive and low voltage instruction.
To conform this product to the EMC Directive and Low Voltage Directive, refer to the
Section of "CC-Link Modules" in Chapter 3 "EMC Directive and Low Voltage
Directive" of the User's Manual (Hardware) of the CPU module used.

1. OVERVIEW MELSEC-A

1. OVERVIEW

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 PLC
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 PLC
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.”

1.1 Features

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 PLC 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 PLC 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.
