4.4. Power Requirements
The WRC-CANR-DF CAN-Bus Extender subsystems are powered from the 11-25 Vdc provided
by the DeviceNet network. The WRC-CANR consumes 60 mA of current at 25 Vdc, or 1.5 Watts, typical.
See Section 3.
4.5. CAN Network Cabling and Configuration
This section provides general guidelines for connecting DeviceNet and SDS systems. You can
find detailed specifications in the referenced ODVA DeviceNet and Honeywell SDS specifications.
4.5.1. Cable Lengths
The following provide cable length limits for DeviceNet and SDS systems. These numbers apply
independently to each physical section of the CAN (copper) network.
