running in cables.

Defining Power Configuration

Power configuration can be adjusted based on the system requirements. A nominal

24 V source provides power supply to the DeviceNet power bus. It can support upto

8 amps on any section based on the trunk cable type used (refer to Cable Types on

page 21 and cable technical specifications) or less electric current using small gauge

cables. For examples on maximum electric current capacity for each cable type,

refer to Cable Types on page 21.

As the electric current drawn from each side of a power tap is more, a single supply

network can possibly provide twice the amount as drawn from a power tap. If the

system requirement is more, DeviceNet can support multiple power supplies that

can result in almost unlimited power. Majority of DeviceNet applications require

only one power supply.

For examples of detailed specifications on the various aspects and components

involved in power, refer to Power Supply on page 54. To install a specific

component, refer to the specifications provided by the component supplier.
