Emerson ships all instruments with two 4-20 mA current outputs.
Current output 1 is the HART communications channel. Current
output 2 is available to report process temperature measured by the
temperature sensing element or resistance temperature device (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.
