  • P1K analog module choice for RTD sensor?

    Since there is not a specific RTD module offer for the P1K, could either the voltage of analog module work? If either could work, which would work best for noise immunity?

    I assume you mean that you would use an RTD transmitter at the RTD? If so, use the MA input module, as RTD to 4-20MA transmitters are quite popular and 4-20MA is much noise immune compared to voltage.

      Thank you for pointing me in the right direction.

      Edit: My next issue is the RTD is nickel, so its 120 ohm rather than 100 ohm. I'll have to scale the signal, right?

      Edit 2: Never mind, found the Pro-sense XTD-0-UNV transmitter. It can read Nickel RTDs. I need to look better
