i need to get out from PoE cable 1A of power in order to drive some LCD Displays and leds, i've digged around and i've found some interesting POE extractor that can fit my requirements (like the RT9400), basically, what i need is:
- Extract power from POE Lan cable in order to use and drive my LCD Displays and led devices
- At the same moment, reuse (with another female RJ45 female port - J2-OUT) the same POE and data to power up and use a olimex ESP32-POE-ISO device (Schematics Here)
Basically, J1-IN has a branch that will go to RT9400 PoE Extraction module, and J2-OUT will go to the ESP32-POE/ISO.
As you can see, i've only wired a part of the total H2019 transformers.
I'm not sure if it will work for two main causes:
- Because the TD and RD transformers of the H2019 will not used
- I don't know what can happen when the two devices will negotiate the POE power supply, the RT9400 is a class 0 signature device
This is the main block logical idea:
It can work? do you have some advices?
