4.2.3 Current Output wiring
The 1066 HART units are shipped with two 4-20mA current outputs. Current Output 1 is loop
power; it is the HART communications channel. Current output 2 is available to report process
temperature measured by the temperature sensing element or RTD within the sensor.
Wiring locations for the outputs are on the main board which is mounted on the hinged door of
the instrument. Wire the output leads to the correct position on the main board using the lead
markings (+/positive, -/negative) on the board.
