I have a system in that we use a 2 wire 4-20ma loop from a transmitter to a programmable relay. We turn a pump off or on depending on levels of the 4-20ma signal. A new customer wants to monitor this 4-20ma signal at their DCS. The units we use do not come with analog outputs. I have included this schematic (it is for general concept, not actual wiring diagram)to show the two ways I believe this could be done. I prefer option #1. Which option would you typically see at a plant?
