We used some 4-20ma current transducers to monitor the current on 4 motors. To make it short the displayed current, via PLC and HMI, is a bit low, 1- 2 amps, when we compare it to our amp clamps. Using the same setup with a different PLC on other jobs with comparable ranges delivers a closer tolerance.
For my purposes I can scale the results to whatever I want but how close are the adjustable overload settings of the starters we use? My FLA may be 24.6 amps but there is no way my glasses focus well enough to dial that in on most of the ones we see.
