[DESIGN PRECAUTIONS]

WARNING

● Make sure to set up the following safety circuits outside the PLC to ensure safe system operation
even during external power supply problems or PLC failure. Otherwise, malfunctions may cause
serious accidents.

- Most importantly, set up the following: an emergency stop circuit, a protection circuit, an interlock

circuit for opposite movements (such as normal vs. reverse rotation), and an interlock circuit (to
prevent damage to the equipment at the upper and lower positioning limits.)

- Note that when the CPU module detects an error, such as a watchdog timer error, during self-

diagnosis, all outputs are turned off. Also, when an error that cannot be detected by the CPU
module occurs in an input/output control block, output control may be disabled. External circuits
and mechanisms should be designed to ensure safe machinery operation in such a case.

- Note that when an error occurs in a relay, transistor or triac of an output circuit, the output might

stay on or off. For output signals that may lead to serious accidents, external circuits and
mechanisms should be designed to ensure safe machinery operation in such a case.

● Construct an interlock circuit in the program so that the whole system always operates on the safe
side before executing the control (for data change) of the PLC in operation.
Read the manual thoroughly and ensure complete safety before executing other controls (for program
change, parameter change, forcible output and operation status change) of the PLC in operation.
Otherwise, the machine may be damaged and accidents may occur due to erroneous operations.

● In an output circuit, when a load current exceeding the current rating 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.

● For the operating status of each station after a communication failure of the network, refer to relevant
manuals for the network. Incorrect output or malfunction may result in an accident.

● To maintain the safety of the programmable controller system against unauthorized access from
external devices via the network, take appropriate measures. To maintain the safety against
unauthorized access via the Internet, take measures such as installing a firewall.

[DESIGN PRECAUTIONS]

CAUTION

● When an inductive load such as a lamp, heater, or solenoid valve is controlled, a large current
(approximately ten times greater than normal) may flow when the output is turned from off to on. Take
proper measures so that the flowing current does not exceed the value corresponding to the
maximum load specification of the resistance load.

● After the CPU module is powered on or is reset, the time taken to enter the RUN status varies
depending on the system configuration, parameter settings, and/or program size.
Design circuits so that the entire system will always operate safely, regardless of this variation in time.

● Simultaneously turn on and off the power supplies of the CPU module and extension modules.

● If a long-time power failure or an abnormal voltage drop occurs, the PLC stops, and output is turned

off. When the power supply is restored, it will automatically restart (when the RUN/STOP/RESET
switch is on RUN side).

To obtain the total number of input/output points, count the input points (X0 and more) and output points (Y0 and more) of the

CPU module and I/O modules.

For details of the number of input/output points by models, refer to the following.

Number of occupied input/output points of intelligent function modules

Count the number of occupied input/output points of intelligent function modules.

The number of occupied input/output points per module is 8.
For details on the number of occupied input/output points by models, refer to Page 36 Intelligent function module.

Calculation of the number of remote I/O points

If the master module of the network is used, calculate the number of remote I/O points connected on the network.

The total number of remote I/O points must not exceed 384 points.

The maximum number of remote I/O points differs according to type of the network.

• When CC-Link IE field network Basic is used, remote I/O points that are used in CC-Link IE field network Basic are

occupied, and then remote I/O points of the intelligent function module are occupied.

• When using CC-Link master (FX3U-16CCL-M) and AnyWireASLINK master (FX3U-128ASL-M) together, connect FX3U-

128ASL-M on the left side. In the FX5UC CPU module, FX3U-16CCL-M parameters are set up by PLC program and will

occupy up to 256 remote I/O points. Therefore, the remote I/O points of FX3U-128ASL-M that is connected to the right side

may be less than 128 points when FX3U-16CCL-M is connected to the left side.

When input/output points are 160 points, FX3U-16CCL-M is connected to the left side of FX3U-128ASL-M, and 256 points of

remote I/O points to be used with FX3U-16CCL-M are occupied: 512 points - 160 points - 256 points = 96 points

Remote I/O points that can be used with FX3U-128ASL-M are 96 points or less.

When input/output points are 160 points, FX3U-16CCL-M is connected to the right side of FX3U-128ASL-M, and the total

number of remote I/O points to be used with FX3U-128ASL-M is 128 points: 512 points - 160 points - 128 points = 224 points

Remote I/O points that can be used with FX3U-16CCL-M are 224 points or less.

• Wiring FX5-CEX/D or FX5-C32ET/D to a subsequent stage

Since the two power connectors on each module of FX5-CEX/D and FX5-C32ET/D are connected in parallel inside the

module, they have no difference and can be either an inlet port or outlet port for supplying the power. Thus, cables can be

connected to either of the connectors.

However, since the lower connector is covered with a resin cover at shipment from the factory, use the upper connector

preferentially. Remove the resin cover only when crossover wiring to a subsequent module is performed.

(FX5-CEX/DS and FX5-C32ET/DSS do not have power connectors and the power is supplied from using input connectors.

Thus, removing the resin cover is not required.)

To perform crossover wiring, supply the power from the preceding module to the subsequent module. The power cannot be

supplied from the subsequent module to the preceding module.

The output wiring of the CPU modules, I/O modules, and terminal modules is explained below.

Transistor output

For output specifications of the CPU modules, refer to Page 24 Output Specifications.
For output specifications of the I/O modules, refer to Page 146 Output specifications.
For output specifications of the terminal modules, refer to Page 162 Output specifications.

Sink and source output

Sink output and source output products are available for transistor outputs of the CPU module, I/O modules, and terminal

modules.

■Differences in circuit

• Sink output [-common] • Source output [+common]

Output to make load current flow into the output (Y) terminal is called
sink output.

Output to make load current flow out of the output (Y) terminal is
called source output.

*1 The number "0" or "1" is applied in .

Handling of transistor output

■Output terminal

For the CPU module, output module (extension connector type), and input/output module (extension connector type), the

transistor output type is a 8-point common output type.

• Sink output • Source output

The COM (number) terminals that are connected each other inside
the PLC are prepared. For external wiring, connect the COM
(number) terminals outside the PLC to reduce the load per one
COM terminal.

The +V (number) terminals that are connected each other inside the
PLC are prepared. For external wiring, connect the +V (number)
terminals outside the PLC to reduce the load per one +V terminal.

■External power supply

For driving the load, use a smoothing power supply of 5 to 30 V DC that can output a current two or more times the current

rating of the fuse connected to the load circuit.

■Insulation of circuit

The internal circuit of the PLC and the output transistor are insulated with a photocoupler.

The common blocks are separated from one another.

■Display of operation

The LED turns on and the output transistor turns on when photocouplers are actuated.

With CPU module, FX5-C32EYT/ or FX5-C32ET/, the LED target is switched with the DISP switch.

• CPU module, FX5-C32ET/: Input (IN)/Output (OUT)

• FX5-C32EYT/: Smaller number (F)/Larger number (L)

■Response time

Time taken from when the photocoupler of the module is driven (or shut off) to when the transistor is turned on (or off) differs

depending on the output terminal used. For specifications of each module, refer to the following.
For output specifications of the CPU modules, refer to Page 24 Output Specifications.
For output specifications of the I/O modules, refer to Page 146 Output specifications.
For output specifications of the terminal modules, refer to Page 162 Output specifications.

The transistor OFF time is longer under lighter loads. For example, under a load of 24 V DC 40 mA, the

response time is approx. 0.3 ms.

When response performance is required under light loads, provide a dummy resistor as shown below to

increase the load current.

Wiring precautions

■Protection circuit for load short-circuiting

A short-circuit at a load connected to an output terminal could cause burnout at the output device or the PCB.

To prevent this, a protection fuse should be inserted at the output. Use a load power supply capacity that is at least 2 times

larger than the load current.

Relay output

For output specifications of the I/O modules, refer to Page 146 Output specifications.
For output specifications of the terminal modules, refer to Page 162 Output specifications.

Product life of relay output contacts

The product life of relay contacts varies considerably depending on the load type used.

Note that loads generating reverse electromotive force or rush current may cause poor contact or welding of contacts which

may lead to considerable reduction of the contact product life.

■Inductive load

Inductive loads generate large reverse electromotive force between contacts at shutdown, which may cause arc discharge. At

a fixed current consumption, as the power factor (phase between current and voltage) gets smaller, the arc energy gets larger.

The following table shows the standard life of contacts used for inductive loads, such as contactors and solenoid valves.

The product life of relay contacts becomes considerably shorter than the above conditions when the rush overcurrent is shut

down.

Please refer to the following measures regarding the inductive load.
Page 99 Contact protection circuit for inductive loads

Some types of inductive loads generate rush current 5 to 15 times the stationary current at activation. Make sure that the rush

current does not exceed the current corresponding to the maximum specified resistance load.

6

■Lamp load

Lamp loads generally generate rush current 10 to 15 times the stationary current. Make sure that the rush current does not

exceed the current corresponding to the maximum specified resistance load.

■Capacitive load

Capacitive loads can generate rush current 20 to 40 times the stationary current. Make sure that the rush current does not

exceed the current corresponding to the maximum specified resistance load.

Capacitive loads such as capacitors may be present in electronic circuit loads including inverters.

■Resistance load

For maximum load specifications of resistance load, refer to the following.
For output specifications of the I/O modules, refer to Page 146 Output specifications.
For output specifications of the terminal modules, refer to Page 162 Output specifications.

■Output terminal

One common terminal is used for 4 or 8 relay output points.

The common terminal blocks can drive loads of different circuit voltage systems (for example: 100 V AC and 24 V DC).

■External power supply

Use an external power supply of 30 V DC or less or 240 V AC or less (250 V AC or less when the module does not comply

with CE, UL, or cUL standards) for loads.

■Insulation of circuit

The PLC internal circuit and external load circuits are electrically insulated between the output relay coil and contact.

The common terminal blocks are separated from one another.

■Display of operation

When power is applied to the output relay coil, the LED is lit, and the output contact is turned on.

■Response time

The response time of the output relay from when the power is applied to the coil until the output contact is turned on, and from

when the coil is shut off until the output contact is turned off is approx. 10 ms.

■Output current

At a circuit voltage of 240 V AC or less (250 V AC or less when the module does not comply with CE, UL, or cUL standards),

a resistance load of 2 A per point or an inductive load of 80 VA or less (100 V AC or 200 V AC) can be driven.
For the life of the contact for switching an inductive load, refer to Page 97 Inductive load.

When an inductive load is switched, connect a diode (for commutation) or a surge absorber in parallel with this load.

DC circuit AC circuit

Diode (for commutation) Surge absorber

■Open circuit leakage current

There is no leakage current when the output are OFF.

Wiring precautions

■Protection circuit for load short-circuiting

A short-circuit at a load connected to an output terminal could cause burnout at the output element or the PCB. To prevent

this, a protection fuse should be inserted at the output.
