I'm looking for facts and opinions on running 24VDC through an ethernet cable to Ethernet/IP remote I/O modules via Passive Injector/Splitter such as this. I've looked up the POE specs so I know that this won't be "legit" POE because it doesn't conform to the voltage spec, but I've also done the math and I think the physics are sound, so long as the Remote I/O power draw is carefully examined. I've attached an example application, powering an Acromag XT1112 16-channel input module and (16) GX3-AP-2E photo sensors through a 100ft Cat 6 copper cable with only 1.2V drop across the cable.
So my question is, would you do it? Why/why not?
