I used to work at a plant that had all honeywell DCS systems and used loop power on 90% of their transmitters. The plant close for lack of business and now I have found myself in a plant using mostly PLC 5's. I have been ask to install 3 loop powered level transmitters but I'm not sure if it can be done using a PLC. On the DCS system the module sent out 0 to 24 volts DC to the transmitter. Based on the resistance of the measuring device it would drop the 24 volts to somewhere between 0 to 24 volts or 4 to 20 milliamps. You would then scale that value. How would I use loop power 2 wire control using the PLC 5. Do I need a special module that would sent out the loop power on one pair and then read back from that module and input value??? The particular device that I am installing is a 5303HA1S1V5AE0200RBE5M1 = $2937.60 from the website Website: http://www.emersonprocess.com/rosemount/products/level/m5300b.html
