Fieldbus Device ListFigure 3-41:
3.19 Power and connect to a FOUNDATION fieldbus
device
The Trex unit can power one FOUNDATION fieldbus device. The Trex unit can provide
approximately 10 volts at 25 mA to power a FOUNDATION fieldbus device. (The Trex unit
will draw approximately 12 mA when it is online).
If you try to apply power from the Trex unit when the device is externally-powered, the
Field Communicator application prevents the Trex unit from supplying power. This
protects the Trex unit from damage.
