Hello Kai,
Thank you for your comments. I checked everything you said. ISO7310C current is 1.8mA:
Finally I replaced 10nF output capacitor by 100nF and the overshoot disappeared.
Best regards, Pablo
Yes, you can. The 2-wire transmitter is meant to be loop powered and you cannot connect the ground of another supply to the I RET of the transmitter as seen in the diagram below.
If you wish to use a sensor with its own supply and ground, you need…
