Do Field point modules (cFP-AI-11) need isolator

[jprk]

Hi friendz,

    We got PAC with I/O's with AI,DI etc.,. In some of our field device(instrument) we got both self power[the field device is powered up externally] and also got loop power, since it got two different power source it will damage the module rite.Do we need provide additional isolator for I/O modules of PAC or its inbuilt, if its inbuilt wats the connection changes need to be made.

Thanks and Regards

Hi Pravin,

Before I can answer your question, I need to know some more information. Please provide answers to the following questions and I will better be able to asist you.

1. What PACs are you using? Are they NI PACs

2. What modules are you using? And how they will be used?

3. What exactly do you mean by "loop power"?
