SIO Isolator RCB-ISL-SIO

Operation Manual First Edition

Thank you very much for purchasing our product.
Make sure to read this Operation Manua l to ensure cor re ct use fo r saf ety.

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

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).

Inside the most PCs, the GND (0V) line for the communication is short-circuited to FG
(frame ground), when the PC is connected, a short-circuit occurs in the 24V power line
which might cause the PC breakdown. In such case, connect the controller (including the
gateway and ROBONET) using the SIO isolator and USB conversion adaptor
(RCB-CV-USB) as shown in the figure.

7. Attachment and Wiring

(1) Procedure

① Because the RC-SIO isolator is attached onto the DIN rail, prepare the

following 35mm DIN rail and end plate.

② Lower the slider to the lowermost position on the rear side of the RC-SIO

isolator.

Slider

Lower the slider to the lowermost position.

③ There is the DIN rail attachment section on the slider on the rear side of the

isolator. Hook the DIN rail on the upper claw in the attachment section as
shown in the picture and set the isolator onto the rail with the pin (spring type)
on the lower position on the attachment section pulled down. Then, finally,
release the pin to lock the isolator.

Hook the DIN rail on the claw.

Pull down the pin.

④ Using the same procedure, attach the required number of isolators onto the

DIN rail.

(3) Pressure Welding Method for the e-Con Connector for the Client-made Cable

(RS485 Communication Line)

Host PLC
Gateway Unit etc.

Use the following procedure for the connection to the
attached e-Con connector.

①Peel off the jacket 15 to 20 mm from the

double shield cable.

②Twist the shield wires and weld them onto the

vinyl cable equivalent to AWG22.

③Cover it with the cable protection tube

(perform the terminal treatment using the
shrink tube).

④Without peeling off the core jacket, insert four

core wires into the connector cable insertion
holes (SDA, SDB, GND, FG).

⑤Keeping the core wires in the holes,

pressure-weld the cable press-fitting housing
from above.

Wire Connection Port

CAUTION

For the connection to the e-Con connector, use the cable with the same core-wire size (equivalent to
AWG22) without peeling off the jacket of that core wires. If the jacket is peeled off, short-circuit might
be caused due to a connection error.
