Indicates a potentially hazardous situation that
could result in death or severe injury if you do
not follow instructions.

Read this manual and follow its instructions. Signal words such as
WARNING, CAUTION and NOTE will be followed by important safety
information that must be carefully reviewed.

Gives you helpful information.

IMPORTANT MESSAGES

The body of unit and this manual contain the essential information for the
protection of users and others from possible injury and property damage
and to ensure correct handling.
Please check that you fully understand the definitions of the following
messages ( symbols ) before going on to read the body of this manual,
and always follow the instructions.
Please also read the instruction manuals etc. of related machines and
understand the contents before use.

Do not disassemble,
modify ( including modification of printed circuit board ) or
repair.

Otherwise injury or failure can result.

Do not operate beyond specification range.

Otherwise fire, malfunction or damage to the reduced wiring system can
result.
Confirm the specifications before operation.

Do not operate in atmosphere of
flammable/explosive/corrosive gas.

Otherwise fire, explosion or corrosion can result.
This reduced wiring system is not explosion-proof type.

Indicates a potentially hazardous situation that, if
not avoided, may result in minor injury or
moderate injury.

For use in interlock circuit:

• Provide double interlock system by adding different type
of protection
( such as mechanical protection ).

• Check that the interlock circuit is working normally.

Otherwise accident caused by malfunction can result.

Before performing maintenance:

• Turn off power supply.

• Stop air supply, exhaust compressed air in piping, and
confirm the release to atmosphere.

Otherwise injury can result.

Conduct proper functional inspection after completing
maintenance.

In the case of abnormality such as unit does not work normally, stop the
operation. Otherwise safety cannot be assured due to unintended
malfunction.

Provide grounding to improve safety and noise resistance of
reduced wiring system.

Provide grounding as close to the unit as possible to shorten distance for
grounding.

NOTE

H

andling precautions

Use the following UL-recognized DC power supply to combine with.

1. UL508-compatible limited voltage/current circuit
A circuit using the secondary coil of an insulating transformer that meets
following conditions as power source.

• Maximum voltage ( at no load ): 30Vrms ( 42.4Vpeak ) or below

• Maximum current: ( 1 ) 8A or less ( including when short-circuited )

( 2 ) When limited by the circuit protector ( such as

fuse ) having the following rating.

2. UL1310-compatible Class 2 power supply unit or circuit of max. 30Vrms
( 42.4Vpeak ) or less using a UL1585-compatible Class 2 transformer as
power source. ( Class 2 circuit )

Follow the instructions given below when handling your
reduced wiring system. Otherwise a damage or failure to cause
a malfunction can result.

• Operate the reduced wiring system at the specified voltage.

• Reserve space for maintenance.

• Do not remove any name plate or label.

• Do not drop, hit or apply an excessive shock to the unit.

• Follow the specified tightening torque.

• Do not apply any excessive force to cables by repeated bending, tensioning

or placing a heavy object on the cables.

• Connect wires and cables correctly.

• Do not perform any wiring work while the power is on.

• Do not use the reduced wiring system on the same wiring route as the

power line or high voltage line.

• Confirm the insulation of wiring.

• Perform the power supply wiring by dividing into two lines ---- one is for

power supply for output and the other is for power supply for input and
controlling GW/SI.

• Take sufficient measures against noise such as noise filter when

incorporating the reduced wiring system into a machine or equipment.

• Mount a terminal plug or a waterproof cap on each unused M12 connector

for input/output
( communication connector, communication ports A - D, and power supply
for input and controlling GW/SI ).

• Take sufficient shielding measures when operating the product in any of the

following places.
( 1 ) A place where noise due to static electricity etc. is generated
( 2 ) A place of high electric field strength
( 3 ) A place where exposure to radioactivity is possible
( 4 ) A place near power cable

• Do not operate the product in a place where there is a source of surge.

• Use a surge absorbing element built-in type to directly drive the load that

generates surge voltage such as solenoid valve.

• Prevent any foreign matter such as remnant of wires from getting inside the

product when opening the station number switch protective cover.

• Install the reduced wiring system in a place free from vibration and impact.

• Operate the product in the specified ambient temperature range.

• Do not use in a place to be affected by the radiant heat from a surrounding

heat source.

• Perform the maintenance regularly.

•

Conduct an appropriate functional inspection after completing the maintenance.

• Do not use chemicals such as benzin and thinner to clean the product.

Installation ( unit : mm )

Wiring

Connect each connector of Input unit, input
blocks, and end block
( portion indicated by arrow in the figure to the
right ).
Holding with hands so that there will be no gap
between blocks, place the jointed unit and
blocks on DIN rail.

Tighten the bolts of Input unit and end block to

secure the jointed unit and blocks to DIN rail.
Be sure to tighten the bolts by proper
tightening torque.
( Tightening torque: 0.6Nm )

ranch wiring

For wiring method, refer to subsection "Wiring" in the Instruction Manual of
EX500.
To input devices such as sensor, the power is supplied through the branch
wiring ( branch cable with M12 connector ). Therefore, there is no need to
supply the power to them individually.

Note: Internal wiring of M12 input block and key position for mounting sensor connector.

• No. 2 pins of M12 input block
connectors are wired to each other’s
sensor signal input pins ( No. 4 pins )
internally.

• This wiring enables direct input of
signals from two points combined into
one cable through concentric
connector etc.

• When connecting sensors, confirm the
specification of output signal carefully.
Otherwise malfunction can result.

• The key position for mounting sensor
connector is as shown to the right.
Consider this key position when
selecting sensor.

NOTE

Mount a waterproof cap on each unused connector of Input unit. The
proper use of waterproof cap can achieve IP65 Enclosure. The waterproof
caps are delivered together with each input block as accessories.
( Tightening torque: 0.05Nm for M8 and 0.1Nm for M12 )
