Note: 1. DC power supply models require a control power supply capacity of approximately 1 A per Unit when power is turned ON. Particular
attention is required when using two or more DC power supply models. The OMRON S8VS-series DC Power Supply Unit is recommend-
ed.
2. PNP input types are also available.
3. For K3HB-series DeviceNet models, use only the DeviceNet Connector included with the product. The crimp terminals provided are for
Thin Cables.
