Appendix C
Using the Relay Terminal Block
This appendix describes how to use the CJ1W-TB101 Wired Controller Link Unit Relay Terminal Block. Using a
Relay Terminal Block enables replacing a Controller Link Unit while network communications are still in
progress.
Relay Terminal Blocks (CJ1W-TB101) can be used on any node but the end nodes to enable replacing the
Controller Link Unit with the communications cable connected and turn OFF the power to only the Unit being
replaced.
Note
The built-in terminating resistance connected at the Units at the end of the network prevents using the
Relay Terminal Block on the end Units.
Connecting the Relay Terminal Block to the Communications
Terminal Block on the Controller Link Unit
1.
Connect the communications cables from the two adjacent nodes together to the terminals on the Relay
Terminal Block. The tightening torque for the Relay Terminal Block terminal screws is 0.5 N·m.
2.
Remove the terminal block cover from the communications terminal block on the Controller Link Unit and
loosen the three screws on the communications terminal block. (If adjacent Units are close enough to inter-
fere with work, remove the three screws.)
3.
Confirming that the signal lines and shield lines are aligned properly with the markings on the Controller Link
Unit, insert the Relay Terminal Block and tighten the screws on the communications terminal block to secure
the Relay Terminal Block. The tightening torque for the three communications terminal block terminal screws
is 0.5 N·m.
