For split/join two 100 Mbit ethernet, to one UTP wire +POE (for use need two module)
POE terminal transfer DC voltage from one end to second
POE limitation MAX 24V/640mA (15W)
Both side center RJ45 connetor LED, show if POE is present
POE voltage and polarity protect with fitration common mode choke on both side
ESD protection with transient voltage suppressor
Ethernet is galvanically isolated, with insulation 2x 1,5 kV
Center single wire recomended use with SFTP cable (shield)
Two grounding potentials GND and PE (Earth) for center line
