Figure A-1. HART / 4–20 mA Wiring Diagram

3144P Single-Sensor connections diagram

3144P Dual-Sensor connections diagram

(1) Transmitter must be configured for a 3-wire RTD in order to recognize an RTD with a compensation loop.

(2) Emerson Process Management provides 4-wire sensors for all single-element RTDs. You can use these RTDs in 3-wire configurations by leaving the unneeded leads

disconnected and insulated with electrical tape.
