RTD Multipexer - Thermal Storage Tank

We have a thermal storage tank here on campus and have proceeded to standardize on Allen Bradley Controlnet PLC's. We are looking to have a single Ethernet drop from the top of the tank from a control panel containing equipment for RTD's direct wired to controller and 2 level transmitters. We were thinking a Allen Bradley 1734-IR2 2CH and an analog card for the level transmitters but not sure this is the right equipment. The RTD's are going to be Weed Instrument (ACCU-TEMP) or approved alternate. Type: Multiple spot temperature RTD assembly. RTD’s shall be housed in a ¾” ID flexible stainless steel hose.

Any help for the Allen Bradley equipment that we would need to communicate control net back to the front end would be great. Thanks in advance guys!!!!
