Product handling
Installation
•Do not drop, hit or apply excessive shock to the product.
Otherwise damage to the product can result, causing malfunction.
•Tighten to the specified tightening torque.
If the tightening torque is exceeded the mounting screws may be broken.
IP67 protection cannot be guaranteed if the screws are not tightened to the specified torque.
•Never mount a product in a location that will be used as a foothold.
The product may be damaged if excessive force is applied by stepping or climbing onto it.
Wiring
•Avoid repeatedly bending or stretching the cables, or placing heavy load on them.
Repetitive bending stress or tensile stress can cause breakage of the cable.
•Wire correctly.
Incorrect wiring can break the product.
•Do not perform wiring while the power is on.
Otherwise damage to the product and/or I/O device can result, causing malfunction.
•Do not route wires and cables together with power or high voltage cables.
Otherwise the product and/or I/O device can malfunction due to interference of noise and surge voltage from power
and high voltage cables to the signal line.
Route the wires (piping) of the product and/or I/O device separately from power or high voltage cables.
•Confirm proper insulation of wiring.
Poor insulation (interference from another circuit, poor insulation between terminals, etc.) can lead to excess
voltage or current being applied to the product, causing damage.
•Take appropriate measures against noise, such as using a noise filter, when the product is incorporated
into equipment.
Otherwise noise can cause malfunction.
Environment
•Select the proper type of protection according to the environment of operation.

If the product is to be used in an environment containing oils or chemicals such as coolant or cleaning solvent, even
for a short time, it may be adversely affected (damage, malfunction etc.).
•Do not use the product in an environment where corrosive gases or fluids could be splashed.
Otherwise damage to the product and malfunction can result.
•Do not use in an area where surges are generated.
If there is equipment which generates a large amount of surge (solenoid type lifter, high frequency induction furnace,
motor, etc.) close to the product, this may cause deterioration or breakage of the internal circuit of the product. Avoid
sources of surge generation and crossed lines.
•When a surge-generating load such as a relay or solenoid is driven directly, use an product with a built-in
surge absorbing element.
Direct drive of a load generating surge voltage can damage the product.

Product Selection
■Selection for low wattage and high wattage load
The type is selected based on the SI unit type and the current consumption of the connect load.
•EX126 and EX250 series (excluding the one power supply system for AS-i)
The Output block for low wattage load should not be used when the current consumption of the connected
output equipment (load) is above the rated current of 62 mA (1.5 W, 24 VDC).
If used, the SI unit will malfunction.
The Output block for high wattage load and a Power block must be used when the current consumption
exceeds the rated load current of 62 mA.

(Output block for low wattage load)
•Location
The Output block for low wattage load cannot be placed closer to the valve manifold than the Power block.
If the Output block for low wattage load is positioned like this, it will not operate.
The correct position is with the Output block for low wattage load located between the SI unit and the
Power block.
[Example]
: There is no continuous line on the product
labels. (Incorrect positioning)
: There is a continuous line on the product
labels. (Correct positioning)

■EX9-OEP
(Output block for high wattage load)
•Combination
The Output block for high wattage load (EX9-OEP) cannot be used independently.
If the Output block for high wattage load is used independently, it will not operate.
It must be used together with a Power block (EX9-PE1).
[Example]
○: This is possible to use it.
×: This is not possible to use it.
•Location
The SI unit or Output block for low wattage load cannot be positioned to the left of the Output block for high
wattage load.
If the Output block for high wattage load is positioned like this, it will not operate.

■Polarity
Be sure to use an Output block with a polarity consistent with the polarity (output style) of the SI unit.
If a product with the incorrect polarity is connected, the Output block will not operate.
[Example]
○: This is possible to use it.
×: This is not possible to use it.
■The number of connected stations
The maximum number of connected stations in total of input / Output blocks (excluding SI unit) is 10.
If more than 10 stations are connected, damage can result due to a lack of strength.
[Example]
○: This is possible to use it.
×: This is not possible to use it.

■Limit of output points when the Output block for high wattage load and Power block are used
•EX250-SDN1, -SMJ2, -SPR1, -SCA1A, -SEN1
The maximum output points of the Output block for low wattage load is 32 (for connector pin No. 3 to 34)
When an Output block for high wattage load and Power block are used, the number of output points of the
Output block (on the right of the Power block) is limited to 24 points (connector pin No. 3 to 26). This is
because 8 points (connector pin No.27 to 34) are used to output the power supply from the Power block to
the Output block for high wattage load (32 points - 8 points =24 points).
