Is it possible to wire loop splitters in series?
I have a couple weidmuller wavepak loop splitters. There's 2 outputs for each splitter and I need 3x outputs so was wondering if it was possible to wire one of the two outputs on the first card to the second giving me 3x independent / usable outputs.
My concern is if the single 4-20 output from our AB analog output card is going to provide a strong enough signal to drive the 2x splitters. Product datasheet states they use optical isolation to minimize signal loss, but just trying to get some definitive info before I pull the pin on this project.

Background:
The issue is we have a single 4-20 output (fan speed control) driving 3 VFD's for glycol cooling fans;
The first VFD gets the signal and simulates an output based on it's operating speed to VFD #2, VFD #2 is controlled by the simulated output from VFD #1 and simulates an output to the VFD #3.
It's functional but the issue is if the first fan in the bank fails we lose 3x fans instead of 1x. And as luck would have it, it's always the first fan in the bank that does fail.
