List of Models
Note: Models with a 24-VDC power supply have a non-isolated 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.
If an unwanted current path exists, use a K8AB AC Power Supply or isolate with an external power supply.
