15 Connecting the RLY OUT Connector
15 Connecting the RLY OUT Connector
The RLY OUT connector connects the status output terminal. It is a normally open contact relay output. The RLY OUT
connector is linked to the operation of the RDY indicator: The contacts close when the indicator lights, and they open
when the indicator goes out.
Note: When the RDY indicator is lit, the Controller is operating normally. It does not necessarily mean that the user programs are being
executed.

RLY OUT Connector Connection Cable
To connect the RLY OUT connector, use a cable with a wire size of AWG 28 to AWG 14 (0.08 to 2.0 mm 2 ) and a
maximum outer diameter of 3.4 mm.
The procedure to make the RLY OUT connector cable is the same as for the 24-VDC power supply cable.
Note: You can use the RLY connector on the Power Supply Unit only on the Rack to which the CPU Unit is mounted. On Racks without
the CPU Unit, the power supply circuit is always open.
