Names and Functions of individual parts
The Input unit manifold consists of Input unit, input block (s), end block
and DIN rail.
The input block up to 8 can be connected ( 16 points ).
Any combination of input blocks ( for M8 connector, M12 connector and
8-point-integrated type ) is acceptable.
Note Do not mix sensor input specifications ( PNP and NPN ).
Figure shows the configuration when only input blocks for M8 connector
are connected.

Installation ( unit : mm )
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 )
Wiring
Branch 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.
Sensor wiring
Connect sensors to the
Sensor connector "1"
sensor connectors of input
Sensor connector "0"
block.

• When connecting sensors, confirm the Input "1" (n+1)
specification of output signal carefully. Input "0" (n)
Otherwise malfunction can result.
M12 Block
• 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 )

Display Description
Power Lights on: Power for input and controlling GW is supplied.
LED Flashing: Under short circuit protection ( abnormal status ).
As the short circuit protective function is operating,
the power is not supplied.
To cancel flashing, turn off and return the power to
GW unit.
Lights off: Power for input and controlling GW is not supplied.
