7.2.2 Powering the networked devices from the RS-485 main data line

Depending on the model, the devices connected to a RS-485 network can be powered from the main data line

as opposed to each device being powered separately. Please check the instruction manual of each device

The AC3011 offers the following options to power devices from the main data line:

a) Power from the same source as the AC3011

This option can be used only when the mA rating of the power supply used for the AC3011 is sufficient to

power both the AC3011 and the networked devices.

b) Power from a separate voltage source
