Hi,
I want to make a simple 4-20mA splitter for use when testing PLCs and save on wiring multiple signal conditioners into input modules.
The problem is i'm not really sure where to start! Does anybody have any tips they can share?
What I need to do is:
1. Using a 24VDC power supply
2. Take a single 4-20mA signal into my circuit
3. Get two 4-20mA signals out which mimic the input signal
The logic to me seems like I would need to amplify my current to double it, and then drop it over two equal resistors afterwards?
Thanks
