E-HELP: Filtering Out AC Noise

E-HELP: Filtering Out AC Noise
Q: Do you have or do you know of a product that will filter out AC noise on an unshielded pair of wires carrying a 4-20mA signal over a distance of approximately 400 feet?

A: Any of our isolators have a common mode rejection AC filtering capability and can be used for this kind of application. 

One popular and versatile option for this is our ECT line. You can see it for yourself by checking out the datasheet, which contains all three types (input loop powered, output loop powered, and line powered.)
