WARNING
• Configure safety circuits external to the programmable controller to ensure that the entire system
operates safely even when a fault occurs in the external power supply or the programmable
controller. Failure to do so may result in an accident due to an incorrect output or malfunction.
(1) Configure external safety circuits, such as an emergency stop circuit, protection circuit, and
protective interlock circuit for forward/reverse operation or upper/lower limit positioning.
(2) When the programmable controller detects an abnormal condition, it stops the operation and
all outputs are:
(a) Turned off if the overcurrent or overvoltage protection of the power supply module is
activated.
(b) Held or turned off according to the parameter setting if the self-diagnostic function of the
CPU module detects an error such as a watchdog timer error.
Note, however, that AnS series modules on the system turn off all outputs in both cases.
All outputs may turn on if an error occurs in a part, such as an I/O control part, where the
CPU module cannot detect any error. To ensure safety operation in such a case, provide a
safety mechanism or a fail-safe circuit external to the programmable controller. For a failsafe circuit example, refer to the user’s manual for the CPU module used.
(3) Outputs may remain on or off due to a failure of an output module relay or transistor.
Configure an external circuit for monitoring output signals that could cause a serious
accident.
A - 1 A - 1
[Design Precautions]
!
WARNING
• In an output module, 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.
• Configure a circuit so that the programmable controller is turned on first and then the external
power supply.
If the external power supply is turned on first, an accident may occur due to an incorrect output
or malfunction.
• For the operating status of each station after a communication failure, refer to relevant manuals
for each network.
Incorrect output or malfunction due to a communication failure may result in an accident.
• When changing data of the running programmable controller from a peripheral connected to the
CPU module or from a personal computer connected to an intelligent function module, configure
an interlock circuit in the sequence program to ensure that the entire system will always operate
safely.
For other controls to a running programmable controller (such as program modification or
operating status change), read relevant manuals carefully and ensure the safety before the
operation.
Especially, in the case of a control from an external device to a remote programmable controller,
immediate action cannot be taken for a problem on the programmable controller due to a
communication failure.
To prevent this, configure an interlock circuit in the sequence program, and determine corrective
actions to be taken between the external device and CPU module in case of a communication
failure.
!
CAUTION
• Do not install the control lines or communication cables together with the main circuit lines or
power cables.
Keep a distance of 100mm or more between them.
Failure to do so may result in malfunction due to noise.
• When a device such as a lamp, heater, or solenoid valve is controlled through an output module,
a large current (approximately ten times greater than normal) may flow when the output is
turned from off to on. Take measures such as replacing the module with one having a sufficient
current rating.
A - 2 A - 2
[Installation Precautions]
!
CAUTION
• Use the programmable controller in an environment that meets the general specifications in the
user’s manual for the CPU module used.
Failure to do so may result in electric shock, fire, malfunction, or damage to or deterioration of
the product.
• To mount the module, while pressing the module mounting lever located in the lower part of the
module, fully insert the module fixing projection(s) in the hole(s) in the base unit and press the
module until it snaps into place.
Incorrect interconnection may cause malfunction, failure, or drop of the module.
When using the programmable controller in an environment of frequent vibrations, fix the
module with a screw.
Tighten the screw 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.
• When using an extension cable, connect it to the extension cable connector of the base unit
securely.
Check the connection for looseness.
Poor contact may cause incorrect input or output.
• When using a memory card, fully insert it into the memory card slot.
Check that it is inserted completely.
Poor contact may cause malfunction.
• Shut off the external power supply for the system in all phases before mounting or removing the
module.
Failure to do so may result in damage to the product.
• Do not touch the module during turning on electricity and immediately after power supply
interception. There is fear of a burn.
• Do not directly touch any conductive parts and electronic components of the module.
Doing so can cause malfunction or failure of the module.

1. GENERAL SPECIFICATIONS AND PRECAUTIONS FOR USE
This chapter describes the general specifications and precautions for use of the I/O
modules.
1.1 General Specifications
Refer to the following manual for the general specifications of the I/O modules.
• QCPU User's Manual (Hardware Design, Maintenance and Inspection)
1.2 Precautions for Use
1.2.1 Input module
(1) Simultaneous ON points
The number of simultaneous on points of input module depends on the input
voltage and ambient temperature.
Refer to the derating chart of the input module specifications.
(2) Input response time and pulse width
Input modules may take in noise or the like as an input depending on the pulse
width of a signal.
This pulse width has a value as listed below depending on the parameter-set
response time. Set input response time while fully consider the operating
environment.

(a) Measure against back EMF
When an inductive load is connected, connect a diode to the load in parallel.
(3) Precautions for using the DC input module
1
Use a diode that meets the following conditions.
• Reverse breakdown voltage is 10 times as high as the circuit voltage or
more.
• Forward current is twice as high as the load current or more.
(4) Precautions for using the high-speed input module
Read the following precautions carefully when using the high-speed input modules
(QX40H, QX70H, QX80H, and QX90H).
(a) When switching to the high-speed input, the specifications of the high-speed
input modules and the input module QX40-S1 are identical. On the other
hand, when switching to the interrupt input, the specifications of the highspeed input modules and the interrupt module QI60 are identical too.
Therefore, the specifications of the input module (QX40-S1) are construed as
the specifications of the high-speed input module switched to the high-speed
input. Similarly, the specifications of the interrupt module (QI60) indicated in
the manuals other than this manual are construed as the specifications of the
high-speed input module switched to the interrupt input.
(b) By using setting switches on the bottom of the module (refer to Chapter 10),
the high-speed input module switches module types (high-speed input or
interrupt input) for 16 input points all together and between valid and invalid
noise filters as shown below.

(c) If the small number of value of input response time is set, the modules tend to
have impact of noise. Ensure that the modules do not have impact of noise.
For details of the measure against noise, refer to the QCPU User’s Manual
(Hardware Design, Maintenance and Inspection).
(d) The high-speed input modules connected with electric appliance such as
relays may load a chattering as a signal.
(e) To use a high-speed input module as a CE marked product, keep the cable
length 3m or less.
1.2.2 Output module
(1) Maximum switching frequency when the module drives inductive load
The output must be on for one second or longer and off for one second or longer.
(2) Load for connection
When connecting a counter or timer that has a DC-DC converter as a load, select
an output module whose maximum load current is larger than inrush current of the
load.
Selecting an output module by average current of the load may cause a failure of
the module because inrush current flows at a constant frequency at power-on or
during operation due to the connected load.
If an output module needs to be selected by average current of the load, take either
of the following actions to reduce an influence from inrush current.
MELSEC-Q
• Connecting a resistor to the load in
series
(3) Replacement of fuses
Fuses installed to an output module cannot be replaced.
(4) Built-in fuses
Built-in fuses works to prevent the external cables from being burned when a short
circuit occurs in the internal output circuit. For this reason, the output module may
not be protected if the fuses blow any other reasons except for a short circuit.
• Connecting an inductor to the load in
series

(b) Measures against inrush current
The actual relay life may be significantly shortened compared to the one shown
in (7)(a), depending on the type of a load connected and the characteristics of
inrush current.
Also, the inrush current may cause contact welding.
Take the following measures to prevent shortening of the relay life and the
contact welding.
• Select a load so that the inrush current will be within the rated current of the
module.
• Connect an external relay that can withstand the inrush current.
The following table shows the relation between the load and the inrush current.
Select a load so that the inrush current (i) and the rated current (io) will be within
the rated switching current specified for the output module used.

(c) Measures against back EMF
Configure a contact protection circuit for extending the contact life, preventing
noise when the contact is cut off, and suppressing the generation of carbide and
nitric acid due to arc discharge.
An Incorrect contact protection circuit may cause contact welding.
Also, when using the contact protection circuit, the recovery time may be long.
The following table shows the representative examples of the contact protection
circuit.

Refer to the following for
constants of the capacitor and
resistor. Note that the
following values may differ
depending on a nature of the
load and a variation of
characteristics of it.
• Capacitor 0.5 to 1 ( F)
against contact current of 1A
• Resistor 0.5 to 1 (Ω)against
contact voltage of 1V
Use a capacitor whose
withstand voltage is 200 to
300V. In AC circuit, use a
capacitor having no polarity.
Use a diode whose reverse
breakdown voltage is 10 times
as high as the circuit voltage
or more and whose forward
current is twice as high as the
load current or more.
Use zener voltage for the
zener diode equal to or more
than the power supply
voltage.
*1: When using AC power, impedance of CR must be larger enough than that of
the load. (prevention of a malfunction due to leak current from the CR)
If a load is from a relay or
solenoid, the recovery time
delays.
A capacitor suppresses
electric discharge while a
contact is off, and a resistor
restricts a flow of current
while a contact is on.
The recovery time is later
than the CR method.
The diode method is effective
when the recovery time is too
late.

POINT
Select a cut voltage (Vc) for
the varistor to meet the
following condition. Multiply
the value by root two for use
of AC power.
Vc Power supply voltage
1.5 (V)
Note that when selecting an
element whose Vc is too high,
its effect will weaken.
The recovery time delays
slightly.
(1) Avoid providing contact protection circuits shown below.
These circuits are effective for preventing an arc at shut-off. However, the
contact welding may occur because the charge current flows to capacitor when
the contact turns on or off.
A DC inductive load is usually harder for switching than a resistor load, but if a
proper protection circuit is configured, the performance will be similar to the
resistor load.
(2) A protection circuit must be provided closely to a load or contact (module). If
their distance is far, the protection circuit may not be effective. Appropriate
distance is within 50cm.

(8) Precautions for using the triac output module
Because of characteristics of a triac, a sudden change of voltage or current may
cause unstable operations of a triac used for the triac output module.
Whether the voltage or current change causes a problem differs depending on an
individual part (each triac), thus check the following when using the triac output
module.
(a) Checking of the load current
When the current consumption is equal to or smaller than the minimum load
current and the margin is low by using an inductive load such as a solenoid
valve, a triac may not turn on or off properly. In that case, an action such as
connecting a bleeder resistance is required.
For detail on actions, refer to Section 11.2.
(b) Precautions on a full-wave rectifier load
The load current of a full-wave rectifier load forms waves similar to rectangular
waves as shown below.
MELSEC-Q
Varistor method
A triac may not operate properly if the current forms rectangular waves
associated with sudden current changes. To avoid it, use a load with which the
load current does not form rectangular waves.
(c) Measures for connecting an inductive load
To connect an inductive load, take measures to reduce noise to the side where
the load is connected as shown below.
Circuit example Method for selecting elements Remarks
Select a cut voltage (Vc) for
the varistor to meet the
following condition.
• Vc > Power supply voltage
1.5(V) √2
This method is not effective
when the Vc is too high.
The recovery time delays
