Operation Manual First Edition
Thank you very much for purchasing our product.
Make sure to read this Operation Manual to ensure correct use for safety.
1. Scope
The RC-SIO isolator is used to isolate the SIO (RS485) communication line
between the controllers.
There are the cases such that the distance to the control box is long, or the
communication ground (0V) line is not shared because both the DC24 type
controllers and AC100V/200V type controllers are used. In such cases, by means
of isolating the communication line using this RC-SIO isolator, the power can be
supplied to each of the controllers independently.
The controllers connectable to this product are as follows.
・PCON-C/CG，CY，SE，CF ・ERC2，ERC2-SE
・ACON-C/CG，CY，SE， ・SCON
・RCP2 ・Gateway Unit
・ROBONET

3. Names and Functions of Each Section
Name Functions
① e-Con Connector Connector for connecting the
communication line (RS485)
with the host or linking the
connectors when two or more
connectors are used.
② POWER LED When the 5V power is supplied
through CN1 (supplied from
the axis 1 controller), it is
turned ON in green. However,
in the case that the
communication speed is slow,
it flashes. When the power is
not supplied, it is turned OFF.
③ SD LED It flashes during the data
transmission from the
controller side to the host side.
When the data transmission is
stopped, it is turned OFF.
④ RD1/RD2 LED It is displayed when the data
receipt in the1st/2nd controller
from the host side. It is turned
ON in green during data
receipt operation. When the
data receipt is stopped, it is
turned OFF.

4. External Dimensions
5. Inner Block Diagram
The communication line (RS485) on the host side is isolated from the
communication line (RS485) on the controller side using the signal isolation IC.
The power to the circuit for the signal isolation IC on the host side is supplied
from the axis 1 controller power unit. Therefore, make sure to connect CN1.
Connect the RCP2 controller to the axis 2 controller (CN2). It can not be connected to the axis
1 controller (CN1).
6. Connection Example
(1) Connection Example 1: In the case that the controller is connected to the host PC through
the SIO link :
In the case that the 0V line for the power to each controller can not be shared, or the
DC24V type controllers are used together with the AC100/200V controllers, the power
source can be separated for each controller as shown in the figure.

2.Because the power to the primary circuit inside the SIO isolator is supplied from CN1, make sure
to connect CN1.
(2) Connection Example 2: In the case that the connector is connected to the host PC or PLC
through the SIO converter :
In the case that the 0V line for the power to each controller can not be shared, or the
DC24V type controllers are used together with the AC100/200V controllers, the power
source can be separated for each controller as shown in the figure .
Because the power to the primary circuit inside the SIO isolator is supplied from CN1, make
sure to connect CN1.
