2.3.2 HART

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.
