Undercurrent Operation Diagram
(Output Relay Drive Method: Normally Closed)
DIP switch setting: SW3 ON.
Note: 1.
The K8AK-AS3 is designed to be used in combination with
the OMRON K8AC-CT200L Current Transformer (CT).
2.
There is no polarity when a DC current input is used.

Relationship of Mounting Distance between
K8AK-AS Relays and Input Current
(Reference Values)
The following diagram shows the relationship between the mounting
distances and the input current. If the relay is used with an input
current that exceeds these values, the temperature of the K8AK may
rise and shorten the life of the internal components.
