Note:
The K8AB-AS3 is designed to be used in combination with the
OMRON K8AC-CT200L Current Transformer (CT).
The 24-VDC power supply type is a non-insulated power
supply.
The inputs and power supply are connected internally, so a
malfunction may occur due to an unwanted current path if the
inputs and power supply are connected to the same line.
