■ Operation and Setting Methods
Setting Ranges and Wiring Connections
Connections
1. Input
2. Power Supply
Note: Models with DC power supply have a non-isolated power supply. The input and power
3. Outputs
Note: Use the recommended ferrules if using twisted wires.
DIP Switch Settings
The resetting method, relay drive method, and operating mode are set using the DIP switch located on the bottom of the Unit.
K8AB-AS@ does not use SW1.

K8AB-AS3
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.
Terminal I1 is not used by the K8AB-AS3.
If using the OMRON K8AC-CT200L CT, connect to terminals k and l on the K8AC-CT200L.
(Terminals kt and lt are not used.)
Connect the power supply to terminals A1 and A2.
SPDT relays are output to terminals 11, 12, and 14.
The current knob (SV) is used to set the current.
The current can be set to 10% to 100% of the maximum measuring current.
Turn the knob while there is an input to the input terminals until the alarm indicator flashes (when the set value and the input have reached the
same level.)
Use this as a guide to set the current.
The maximum measuring current will differ depending on the model and the input terminal.
Example: K8AB-AS3 Using Input Terminals I3-COM
Model
supply terminals are connected internally so the K8AB-AS will not operate normally if an
unwanted current path is created. If an unwanted current path exists, use a model with an
AC power supply or isolate with an external power supply.
The maximum measuring current will be 200 A AC and the setting range will be 20 to 200 A.
