PROCESS DEVICE WITH DIAGNOSTIC ANNUNCIATION

A process device for coupling to a two-wire process control loop-includes diagnostic circuitry configured to identify a failure or reduced level of performance or provide a prediction of a future failure or reduced level of performance. An output coupled to the two-wire process control loop is confi...

Zusammenfassung:A process device for coupling to a two-wire process control loop-includes diagnostic circuitry configured to identify a failure or reduced level of performance or provide a prediction of a future failure or reduced level of performance. An output coupled to the two-wire process control loop is configured to provide an analog output on the loop related to an output from the diagnostic circuitry.
