Internal resistors
The Trex unit has internal resistors that can be used when the Trex unit powers a HART
transmitter, or when the HART transmitter is on a 4-20 mA current loop without a resistor.
The resistors are enabled through the device connection wizard in the Field Communicator
application.
Note
For positioners, the internal resistors in the Trex unit are disabled.
