1. General
This unit is a remote device station of CC-Link Ver.1.10.
This unit can be connected with the mastering station of CC-Link Ver.1.10.
1-1. Features
Main features for CSD-903-73 are as follows:
(1) This unit can be controlled by using remote I/O and register of the PLC, so the program volume of
the PLC can be reduced.
(2) The wiring with the PLC can be reduced.

3. Connecting method
3-1. Connector pin configuration for communication
Refer to “2-1.Rear panel for CC-Link I/F (1) Connector for communication”.
3-2. Notes of Connection
When the wiring, be sure to the instrument power supply is OFF.
Do not supply the AC power until complete the installation. This instrument does not have power
switch (ON/OFF).
Do not fell or make a strong impact on this instrument rear panel terminal block because it is made of
resin.
Striped electrical cable tip length is 6 mm.
The tightening torque of terminal screws on the terminal block is 0.6 N･m.
Cables which connecting this instrument isolate from noise sources, for example, power supply line
and I/O for control's as much as possible.
Be sure to connect the ground wire must be D single ground. Do not common the ground with a kind
of power supply.
For CC-Link cable connection, use twist pear cable wire with shield (Cable for CC-link) and connect
the shield in terminal block's SLD terminal or F.G. terminal.
・ Connect the termination to the CC-Link connector to electrical termination which is far from PLC as
possible.
・ Use the connecting cable for CC-Link.
・ Refer to the “Construction and specification of network system” from the latest version of
CC-Link Cable Wiring Manual published by CC-Link Partner Association about communication
speed and cable length

4. Setting of CC-Link connecting
Please set the following when you use CC-LINK interface.
4-1. Changeover to Function mode
Change from the standard measurement mode to the function mode by the following operations.
1) Press the SET key.
2) The display becomes “FUNC”, and press the F key.
3) Select function number which you want to change.
Refer to clause 7 of the CSD-903 instruction manual (DRW No.EN294-1492) for “Setting method of the
