Connections
Input
Connect the input between the I1-COM, I2-COM, or I3-COM terminals, according to the input
current. Malfunctions may occur if the input is connected to unused terminals and the Unit will not
operate correctly.
For the K8DT-AW3, the I1 terminal is not used. For the K8DT-AW2, the I3 terminal is not used.
If using the OMRON K8AC-CT200L CT, connect to terminals k and l on the K8AC-CT200L.
(Terminals kt and lt are not used.)
Power Supply
Connect the power supply to terminals A1 and A2.
Outputs
For a relay output, the SPDT contacts are output on terminals 11, 12, and 14. For a transistor output,
the NPN output is on terminals 11 and 14.
Do not use the transistor output for control applications. It is designed only to output a signal when
an error is detected.

DIP Switch Settings

The reset method and operating mode are set using the DIP switch located on the front of the Unit.
K8DT-AW@ does not use SW1.
Note: Open the DIP switch cover to set the DIP switch.
Keep the DIP switch cover closed while the power supply to the Relay is ON.
