Answer	—	A: PCB ground planes with isolated voltage This isn't a direct answer to your questions, but you should be aware of that to maintaining isolation means careful design off the PCB as well. You would do well to remember that if you are planning to have two isolated grounds you have to arrange everything so that the isolated grounds (or their... (more)	—	almost 2 years ago

Answer	—	A: How do PLCs normally measure 4-20mA current loops? You can predictably generate a voltage with a R-2R ladder or a Rn^2 selector and then use a commodity V-I industrial converter interface to generate the current loop the customer desires. You cannot make assumptions of the shunt resistance that the receiver will present, it may not even be purely... (more)	—	almost 2 years ago
