Note
Do not apply high voltage (e.g., AC line voltage) to the power or sensor terminals, since high voltage can
damage the unit.

1. Transmitter must be configured for a 3-wire RTD in order to recognize an RTD with a compensation loop.
2. Emerson provides 4-wire sensors for all single-element RTDs. Use these RTDs in 2- or 3-wire configurations by leaving the unneeded leads
disconnected and insulated with electrical tape.
