1 OUTLINE
This product is an input/output unit which can be used in combination with the up-
per communication unit (SC-GU3-0 , SC-GU1-485, SC-GU2-C).
An output device of NPN output type or analogue voltage/current output type can
be connected to this product.
This product has resolution of 1/4,000 (12 bits).
The analogue input range is 1 to 5V for SC-A01, and 4 to 20mA for SC-A02.

3. Pressure weld the connector using a plier or the like.
• For pressure welding, make sure to apply the plier in parallel with the connector,
from the direction indicated below.
• Pay attention not to damage the wire with the plier while pressure welding.
• Make sure that the wire does not become loose while pressure welding.

1. Mount the communication unit
SC-GU3-0 to the DIN rail.
When doing this, remove the
end connector cap from the joint
connector part of this product.
2. Mount the joint connector unit
SC-71 one by one to the DIN
rail, and slide them toward the
SC-GU3-0 .
3. Insert this product SC-A0

8 CAUTIONS
This product has been developed / produced for industrial use only.
Make sure that the power supply is OFF while wiring and adding the units.
Take care that if a voltage exceeding the rated range is applied, or if an AC power
supply is directly connected, the product may get burnt or damaged.
Make sure to check the wiring as wrong wiring can damage or burn the product.
Do not run the wires together with high-voltage lines or power lines or put them in
the same raceway. This can cause malfunction due to induction.
Joint connector unit SC-71 (optional)
Verify that the supply voltage variation is within the rating.
If power is supplied from a commercial switching regulator, ensure that the frame
ground (F.G.) terminal of the power supply is connected to an actual ground.

Take care that if noise is applied to the analogue voltage input, the product may
malfunction.
