*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 recommended.
*2. The five displayed digits are stored in memory.
*3. For K3HB-series DeviceNet models, use only the DeviceNet Connector included with the product. The crimp terminals
       provided are for Thin Cables.
