Hello , I have a problem with the EM235 and it is the following: when I connect to an entrance a |presostato| with projecting 4..20 MA the reading of the modulate is stable. However when connect you the |presostato| to the cable of30 |mts| in long robes to the EM235 entrance, it fluctuates the reading. We have exchanged the cable and the earth is good. The curious thing is that the other two canals are regular guest, and too have connected |presostatos|. That can be? Thank you for you answer. Splitted from Analog Input Raw Value Fluctuation in S7200. |
