This manual describes the specifications of the CC-Link embedded I/O adapter used
as the remote I/O station of a Control & Communication Link (hereafter abbreviated to
CC-Link) system.
The following are the features of the CC-Link embedded I/O adapter.
(1) Device-embedded CC-Link remote I/O
This adapter is a modular remote I/O used as a device-embedded adapter.
(2) Direct installation to user board
Using a pin header as the external interface for adapter power supply,
transmission, I/O signals and others, the adapter can be installed directly to a
user board.
(3) Flexible noise reduction measures
Depending on external noise environment, the user board can be equipped with
a noise filter to enhance noise resistance as necessary.
(4) Insulation method
The adapter power supply uses a transformer insulation method and the external
I/O uses a photocoupler insulation method.
(5) Overload protection function, overvoltage protection function and
overheat protection function
The transistor output section has the overload, overvoltage and overheat
protection functions.
(6) Cascade connection
The CC-Link embedded I/O adapters can be cascaded. Two CC-Link embedded
I/O adapters can be installed side by side within the same board.

1 OVERVIEW
1.3 Cautionary Notes when Selecting a CC-Link Embedded I/O Adapter
The following explains the cautionary notes and specifications that apply when
selecting a CC-Link embedded I/O adapter for use in the CC-Link system:
(1) This is a embedded I/O adapter designed specifically for the CC-Link system.
Do not connect the adapter to other data-link systems, such as the
MELSECNET/MINI.
(2) 32 points are assigned per station for a CC-Link embedded I/O adapter.
The second-half 16 points of a 16-point CC-Link embedded I/O adapter are empty
but are not usable.
(3) For the maximum switching frequency when driving a load in the CC-Link
embedded output adapter, set to one second or more each for ON and OFF.
(4) When using a counter, a timer or the like that uses a DC/DC converter as the load
for a CC-Link embedded transistor output adapter having a maximum load current
of 0.1A, a rush current flows when the adapter is turned on and at fixed intervals
during operation. For this reason, malfunctions may occur if the average current
is set. When the above load is used, connect resistance or inductance in parallel
to the load, or use an output adapter having a large maximum load current in
order to minimize the effects of the rush current.

(5) When using the AJ65MBTL1N-16D, AJ65MBTL1N-16DT or AJ65MBTL1N-32D
CC-Link embedded I/O adapter, the maximum number of simultaneous input
points listed in the specifications will change, depending on the ambient
temperature.
The maximum number of simultaneous input points is shown in the diagram

5 HANDLING CC-Link EMBEDDED I/O ADAPTER
5.1 Precautionary Notes for Handling and Installation
MELSEC-
5
DANGER
CAUTION
The precautionary notes when handling and installing the CC-Link embedded I/O
adapter for the CC-Link system are described below.
• Do not touch the terminals or connector while the power is on.
Doing so may cause electric shock or malfunction.
• Make sure that there are no foreign substances such as sawdust or wiring debris
inside the CC-Link embedded I/O adapter.
Such debris could cause fire, failure or malfunction.
• Do not disassemble or modify the CC-Link embedded I/O adapter.
Doing so could cause failure, malfunction, injury or fire.
• Do not directly touch the CC-Link embedded I/O adapter's conductive parts.
Doing so could cause malfunction or failure in the CC-Link embedded I/O adapter.
• Because the case of the CC-Link embedded I/O adapter is made of resin, be careful
not to drop it or expose it to strong impact.
It may damage the CC-link embedded I/O adapter.
• When disposing of this product, treat it as industrial waste.
• Use the CC-Link embedded I/O adapter in an environment that meets the general
specifications contained in this manual.
Using this adapter in an environment outside the range of the general specifications
could result in electric shock, fire, malfunction, and damage to or deterioration of the
product.
• Before mounting or dismounting the user board loaded with the CC-Link embedded
I/O adapter to or from an enclosure, always switch power off externally in all
phases.
Failure to do so may damage the CC-Link embedded I/O adapter or cause
malfunction.
(1) Restrictions on close installation
Because of heat generation, do not install the CC-Link embedded I/O adapters
closely to each other.
Install the CC-Link embedded I/O adapters at least 5mm away from each other.

5 HANDLING CC-LINK EMBEDDED I/O ADAPTER
(2) Precautions for external wiring
Adapter power supply
Note the following when designing the user board side circuit and board patterns.
1) Use a user board of 1.6mm thickness.
2) When the noise immunity must be increased, insert a noise filter (FDK
make: NFR5UI203MB or equivalent) and Y capacitor (22000pF 630V) in the
adapter power supply line.
3) Connect the transmission SLD and FG within the board.
As a pattern, connect SLD and FG as near as possible to the external I/O
terminals.
4) Make the transmission patterns (DA, DB) as short as possible.
Design the patterns so that the capacitance is 20pF or less with the CC-Link
embedded I/O adapter mounted on the board. (Guidelines: Pattern length
5cm or less, pattern width 0.18mm or less)
5) Since the cascade communication signal pins (16-point adapter: A17 to A20
pins and B17 to B20 pins, 32-point adapter: A26 to A29 pins and B26 to B29
pins) are susceptible to noise, keep them as far away as possible from the
other patterns (power supply, I/O signal) that include noise.
6) When the adapters are not cascaded, always connect GND and RDGON
(16-point adapter: A17 pin and A18 pin, 32-point adapter: A26 pin and A27
pin) on the board side.
7) Wire the FG pattern so that it does not cross the I/O patterns on the front
and back sides of the board.
Doing so makes the adapter sensitive to noise.

(The points are paired as Y0/Y1, Y2/Y3, etc., and the overheat protector is activated
for two points in a pair simultaneously. If the overheat condition is prolonged, the
heat spreads and other overheat protectors may also be activated.)
2. The actual output voltage oscillates in the range of 0 V to the load voltage only if the
output is ON when the overheat protection function was activated. In this case, the
average voltage during oscillation with the load voltage of 24 V is approximately 7 V.
(No oscillation occurs when the output is OFF.)
To ensure that output turns OFF when the overheat protection function is activated,
use an external load that turns OFF at 7 V or more.
3. The overheat protection function automatically returns to normal operation when the
heat drops.

5.3 Connection Method of CC-Link Dedicated Cable
The procedure for connecting the master adapter and I/O adapter CC-Link dedicated
cable is shown below.
DANGER
CAUTION
• Before beginning any installation or wiring work, make sure all phases of the power
supply have been obstructed from the outside.
Failure to completely shut off the power supply phases may cause electric shock
and/or damage to the adapter.
• Make sure to switch all phases of the external power supply off before cleaning or
re-tightening the terminal screws.
Failure to do so may damage the CC-Link embedded I/O adapter or cause
malfunction.
• 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 100 mm (3.9 in.) or more from each other.
Not doing so could result in noise that would cause malfunction.
• Always ground the FG terminal to the protective ground conductor.
Doing so may cause electric shock or malfunction.
• Securely solder the CC-link embedded I/O adapter to install it to a user board.
Defective contact could cause malfunction.
• Make sure that the communication cable connected to the adapter is kept in the
duct or fixed with cramps.
Failure to do so may cause a damage to the user board or cables due to dangling,
shifting or inadvertent handling of cables, or misoperation because of bad cable
contacts.
• Do not grab on the cable when removing the communication cable connected to the
adapter.
When removing the cable with a connector, hold the connector on the side that is
connected to the adapter.
When removing the cable without a connector, loose the screws on the side that is
connected to the adapter.
Pulling the cable that is still connected to the adapter may cause a damage to the
user board or cable, or malfunction due to bad cable contacts.
