[Design Precautions]
[Design Precautions]
WARNING
●In an output circuit, when a load current exceeding the rated current or an overcurrent caused by a
load short-circuit flows for a long time, it may cause smoke and fire. To prevent this, configure an
external safety circuit, such as a fuse.
●Do not write any data to the "system area" and "write-protect area" (R) of the buffer memory in the
intelligent function module. Also, do not use any "use prohibited" signals as an output signal from the
programmable controller CPU to the intelligent function module. Doing so may cause malfunction of
the programmable controller system.
●Outputs may remain on or off due to a failure of a transistor for external output. Configure an external
circuit for monitoring output signals that could cause a serious accident.
●When changing data and operating status of the running module from an external device such as a
personal computer connected, configure an interlock circuit external to the programmable controller to
ensure that the entire system always operates safely.
In addition, before performing online operations, determine corrective actions to be taken between the
external device and the module in case of a communication failure due to poor contact of cables.
CAUTION
●Do not install the control lines or communication cables together with the main circuit lines or power
cables. Keep a distance of 150mm or more between them. Failure to do so may result in malfunction
due to noise.
●During control of an inductive load such as a lamp, heater, or solenoid valve, a large current
(approximately ten times greater than normal) may flow when the output is turned from off to on.
Therefore, use a module that has a sufficient current rating.
WARNING Indicates that incorrect handling may cause hazardous conditions, resulting in
death or severe injury.
CAUTION Indicates that incorrect handling may cause hazardous conditions, resulting in
minor or moderate injury or property damage.

[Installation Precautions]
[Installation Precautions]
[Wiring Precautions]
WARNING
●Shut off the external power supply (all phases) used in the system before mounting or removing a
module. Failure to do so may result in electric shock or cause the module to fail or malfunction.
CAUTION
●Use the programmable controller in an environment that meets the general specifications in the Safety
Guidelines provided with the CPU module or head module. Failure to do so may result in electric
shock, fire, malfunction, or damage to or deterioration of the product.
●To interconnect modules, engage the respective connectors and securely lock the module joint levers
until they click. Incorrect interconnection may cause malfunction, failure, or drop of the module.
●Do not directly touch any conductive parts and electronic components of the module. Doing so can
cause malfunction or failure of the module.
WARNING
●Shut off the external power supply (all phases) used in the system before wiring. Failure to do so may
result in electric shock or cause the module to fail or malfunction.
●When connecting a differential output terminal to a differential receiver of a drive unit, connect the
high-speed output common terminal to the differential receiver common terminal of the drive unit.
Failure to do so may cause the module to fail or malfunction because of the potential difference that
occurs between the high-speed output common terminal and the differential receiver common
terminal.

[Wiring Precautions]
[Startup and Maintenance Precautions]
CAUTION
●Individually ground the FG and LG terminals of the programmable controller with a ground resistance
of 100 ohms or less. Failure to do so may result in electric shock or malfunction.
●Check the rated voltage and terminal layout before wiring to the module, and connect the cables
correctly. Connecting a power supply with a different voltage rating or incorrect wiring may cause a fire
or failure.
●Connectors for external devices must be crimped with the tool specified by the manufacturer or must
be correctly soldered. Incomplete connections may cause short circuit, fire, or malfunction.
●Place the cables in a duct or clamp them. If not, dangling cable may swing or inadvertently be pulled,
resulting in damage to the module or cables or malfunction due to poor contact.
●Tighten the connector screws within the specified torque range. Undertightening can cause drop of
the screw, short circuit, fire, or malfunction. Overtightening can damage the screw and/or module,
resulting in drop, short circuit, fire, or malfunction.
●Prevent foreign matter such as dust or wire chips from entering the module. Such foreign matter can
cause a fire, failure, or malfunction.
●A protective film is attached to the top of the module to prevent foreign matter, such as wire chips,
from entering the module during wiring. Do not remove the film during wiring. Remove it for heat
dissipation before system operation.
●Ground the shield cable on the encoder side (relay box). Always ground the FG and LG terminals to
the protective ground conductor. Failure to do so may cause malfunction.
●Mitsubishi programmable controllers must be installed in control panels. Connect the main power
supply to the power supply module in the control panel through a relay terminal block. Wiring and
replacement of a power supply module must be performed by qualified maintenance personnel with
knowledge of protection against electric shock. For wiring methods, refer to the MELSEC-L CPU
Module User's Manual (Hardware Design, Maintenance and Inspection).
WARNING
●Do not touch any terminal while power is on. Doing so will cause electric shock or malfunction.
●Shut off the external power supply (all phases) used in the system before cleaning the module or
retightening the connector screws. Failure to do so may result in electric shock.

[Startup and Maintenance Precautions]
[Disposal Precautions]
CAUTION
●Do not disassemble or modify the module. Doing so may cause failure, malfunction, injury, or a fire.
●Shut off the external power supply (all phases) used in the system before mounting or removing a
module. Failure to do so may cause the module to fail or malfunction.
●After the first use of the product (module and display unit), do not connect/disconnect the product
more than 50 times (in accordance with IEC 61131-2). Exceeding the limit may cause malfunction.
●Tighten the connector screws within the specified torque range. Undertightening can cause drop of
the component or wire, short circuit, or malfunction. Overtightening can damage the screw and/or
module, resulting in drop, short circuit, or malfunction.
●Before handling the module, touch a conducting object such as a grounded metal to discharge the
static electricity from the human body. Failure to do so may cause the module to fail or malfunction.
●When performing online operations of the running module from an external device such as a personal
computer connected, read the relevant manuals carefully and ensure that the operation is safe before
proceeding.
●Before changing any setting of the module, read the relevant manuals carefully, ensure the safety,
and change the operating status of the CPU module to STOP.
Especially when operating the module in the network system, ensure the safety thoroughly because

1FLEXIBLE HIGH-SPEED I/O CONTROL
MODULE
For the flexible high-speed I/O control module, users can easily create a high-speed, complicated hardware logic independent
from the CPU module by graphically combining input/outputs, logical operation circuits, and counters with the configuration
tool.
1.1 Features
Controls that have been performed using a microcomputer board or an FPGA board or combining several modules can be
performed only with the flexible high-speed I/O control module.
• High-speed, high-response control with μs orders
• Controls with stable response time
• Logic controls that requires rapidity
• Measurement control with sensor inputs
• Controls triggered by external inputs
By using this module instead of a microcomputer board or an FPGA board, which cannot be supplied steadily and constantly
due to their high introduction cost and design cost, users can configure a system only with a programmable controller,
reducing man-hours and the total system cost.
