Store this manual in a safe place so that it can be read whenever necessary. Always forward it to the end user.

[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 forward 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 machine operation in such a case.

- Note that the output current of the 24 V DC service power supply varies depending on the model

and the absence/presence of extension modules. If an overload occurs, the voltage automatically drops, inputs in the PLC are disabled, and all outputs are turned off. External circuits and mechanisms should be designed to ensure safe machine operation in such a case.

- Note that when an error occurs in a relay or transistor 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 machine operation.

● 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, forced 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.

[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).

Calculation of 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.

Precautions when using CC-Link master (FX3U-16CCL-M) and AnyWireASLINK master (FX3U-128ASL-M) together

When using FX3U-16CCL-M and FX3U-128ASL-M together, connect FX3U-128ASL-M on the left side. In the FX5U 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 and CC-Link master are 256 points: 512 points - 160 points - 256 points = 96 points

Remote I/O points of AnyWireASLINK master are 96 points or less.

6.6 Output Wiring

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

Relay output

For output specifications of the CPU module, refer to Page 21 Output Specifications. For output specifications of the I/O modules, refer to Page 136 Output specifications.

Product life of relay output contacts

The product life of relay output 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 standard life of contacts used for inductive AC loads, such as general contactors and solenoid valves, is 500,000

operations at 20 VA.

The following table shows the approximate life of a relay based on the results of an operation life test.

• Test condition: 1 sec. ON/1 sec. OFF

Load capacity Contact life

20 VA 0.2 A/100 V AC 3,000,000 times

0.1 A/200 V AC

35 VA 0.35 A/100 V AC 1,000,000 times

0.17 A/200 V AC

80 VA 0.8 A/100 V AC 200,000 times

0.4 A/200 V AC

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 91 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.

■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 CPU module, refer to Page 21 Output Specifications. For output specifications of the I/O modules, refer to Page 136 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, 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, 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 89 Inductive load.

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

Sink and source output

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

Handling of transistor output

■Output terminal

4 or 8 transistor output points are covered by one common terminal.

• Sink output • Source output

Connect each COM (number) terminal to the minus side of the load power supply. The COM terminals are not connected internally.

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

Connect +V (number) terminal to the plus side of the load power supply. The +V terminals are not connected internally.

■External power supply

For driving the load, use a smoothing power supply of 5 to 30 V DC that can output 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

Operation indicator LEDs are built into the CPU module and output modules, and turn ON when photocouplers are activated,

and the transistors are switched on.

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 module, refer to Page 21 Output Specifications. For output specifications of the I/O modules, refer to Page 136 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.
