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-912-73 are as follows:
（1） This unit can be controlled by using remote I/O and register of the sequencer, so the program volume
of the sequencer can be reduced.
（2） The wiring with the sequencer 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
zWhen the wiring, be sure to the instrument power supply is OFF.
zDo not supply the AC power until complete the installation. This instrument does not have power
switch (ON/OFF).
zDo not fell or make a strong impact on this instrument rear panel terminal block because it is made
of resin.
zStriped electrical cable tip length is 6 mm.
zThe tightening torque of terminal screws on the terminal block is 0.5～0.6 N･m.
zCables which connecting this instrument isolate from noise sources, for example, power supply line
and I/O for control's as much as possible.
zBe sure to connect the ground wire must be D single ground. Do not common the ground with a
kind of power supply.
zFor 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
