[Design Instructions]
!DANGER
• Install a safety circuit external to the PLC that keeps the entire system safe if there are problems
with the external power supply or PLC. Not doing so may cause false output or malfunction,
leading to accidents.
(1) Outside the PLC, construct mechanical damage preventing interlock circuits, e.g. emergency
stop circuits, protective circuits, forward/reverse or other conflicting operation interlocking
circuits, and upper and lower positioning limit switches.
(2) When the PLC detects either of the following problems, it will stop arithmetic operation and
turn off all outputs in the case of (a). In the case of (b), it will stop arithmetic operation and
hold or turn off all outputs according to the parameter setting.
(a) The overcurrent protection or overvoltage protection of the power supply module is
activated.
(b) The self-diagnostic function of the PLC CPU has detected a fault such as the watchdog
timer error.
In addition, all outputs may be turned on when there are problems undetectable by the PLC
CPU, such as in the I/O controller. Build a fail-safe circuit or provide a mechanism externally
of the PLC to operate the machine safely at such times. Refer to the CPU module user's
manual for fail-safe circuit examples.
(3) Output could be left on or off when there is trouble in the output module's relays, transistors,
etc. So build an external monitoring circuit that will monitor any output signal that could lead
to a serious accident.

A - 2 A - 2
[Design Instructions]
!DANGER
• When overcurrent exceeding the rated load current or caused by a shorted load or the like flows
in the output module for a long time, it may cause smoke or fire. To prevent this, configure an
external safety circuit, such as fuses.
• Build a circuit that turns on the external power supply after the PLC power supply has been
turned on. If the external power supply is turned on first, it could result in false output or
malfunction.
• When there are communication problems with the data link, refer to the corresponding data link
manual for the operating status of each station. Not doing so could result in false output or
malfunction.
• When connecting a peripheral device to the CPU module or connecting a personal computer or
the like to the intelligent function module to exercise control (data change) on the running PLC,
configure up an interlock circuit in the sequence program to ensure that the whole system will
always operate safely.
Also before exercising other control (program change, operating status change (status control))
on the running PLC, read the manual carefully and fully confirm safety.
Especially for the above control on the remote PLC from an external device, an immediate
action may not be taken for PLC trouble due to a data communication fault.
In addition to configuring up the interlock circuit in the sequence program, corrective and other
actions to be taken as a system for the occurrence of a data communication fault should be
predetermined between the external device and PLC CPU.
!CAUTION
• Do not bundle the control wires or communication cables with the main circuit or power wires, or
run them close to each other.
They should be run 100mm (3.94in.) or more away from each other.
Not doing so could result in noise that would cause malfunction.
• When the output module is used to control a lamp load, heater, solenoid valve or the like, large
current (approximately 10 times greater than the normal) may flow when the output is turned
from OFF to ON. Choose an output module having a sufficient rated current.

A - 3 A - 3

MODULE
1. GENERAL SPECIFICATIONS MODULES AND PRECAUTIONS FOR USE
OF I/O MODULE
This chapter describes the general specifications and precautions for use of I/O
module.
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) The number of simultaneous on points of input module depends on its input voltage
and ambient temperature.
Refer to the number of simultaneous on points shown on the specifications of each
input module.
(2) 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.
Setting value of response time (ms)
Minimum value of pulse width
where noise or the like may be
taken in as an input (ms)
1 0.3
5 3
10 6
20 12
70 45
For settings of the input response time, refer to Section 1.3.1.
(3) Read the following precautions carefully for use of 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 high-
speed 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.

*1: When selecting an improper module type, an error (error code: 2100)
occurs.
*2: Setting the input response time with GX Developer is ignored.
(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 the details of the measure against noise, refer to 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) Select a cable whose length is three meters or less, when using the high-
speed input module as a CE-compatible product.
1.2.2 Output module
(1) If an output module drives load, its maximum switching frequency must be on for
one second or longer and off for one second or longer.
(2) If a counter or timer which has a DC-DC converter as a load is used with an output
module, choosing an output module by its average current can cause a failure due
to periodic inrush current at power-on or during operation.
To reduce the influence of inrush current for use of the above load, connect a
resistor or an inductance to the load in series or use a module whose maximum
load current is large.

(3) Fuses installed to an output module cannot be replaced.
(4) Fuses installed to an output module are to prevent external wiring from being
burned in case that outputs of the module short.
Therefore, if the fuses became a failure due to other than a short-circuit, the output
modules may not be protected.

POINT
(1) When using the module for the application in which the relay contact is
frequently switched, the relay life span should be considered. Therefore, it is
recommended to use a triac output module.
(2) The relay life curve shows the value based on actual use, which is not
guaranteed. Therefore, make sure to allow for a margin of error.
The relay life span differs according to the specifications as follows:
• Rated switching voltage, current load 100 thousand times
• 200VAC 1.5A, 240VAC 1A (COS =0.7) 100 thousand times
• 200VAC 0.4A, 240VAC 0.3A (COS =0.7) 300 thousand times
• 200VAC 1A, 240VAC 0.5A (COS =0.35) 100 thousand times
• 200VAC 0.3A, 240VAC 0.15A (COS =0.35) 300 thousand times
• 24VDC 1A, 100VDC 0.1A (L/R=7ms) 100 thousand times
• 24VDC 0.3A, 100VDC 0.03A (L/R=7ms) 300 thousand times
