0-10V Output
0-10V Output
(OP)
Job has 5 existing 0-10V outputs for process, I need to add
a recorder for the process. The distance is approx. 150-200
feet. Is it possible to add a signal duplicator, and then
convert one of the outputs to 4-20ma for the recorder!

RE: 0-10V Output
You're sure the recorder doesn't take a 0-10V input? If it does, then pulling a twisted pair of wires to test a 200' run with the 0-10V signal would be feasible. Why not try the voltage signal before you go to 4-20?

I've done it where it's worked OK, and where it hasn't. The problem where it didn't work was noise.
Since you need a twisted pair wire run, why not pull the wire, connect it up and see what the recorded signal looks like? If it's clean, you're up and running. If it's too noisy, then you'll have to get an I/O module and convert to 4-20.

You have a good chance of the 0-10V working as that is a large signal. Think of thermocouple signals that often run hundreds of feet thru industry and work well enough with microvolt signals.
