Overview
The PoE powered device reference design demonstrates IEEE 802.3at 13W power delivery and 10/100 Ethernet communication using low cost standard cabling. The design can read 4 RTD temperature sensors and control 4 Triac’s connected to resistive headers.
The PCB is isolated into 3 areas. First is the PoE section isolated from the digital section via 48V to 5V transformer. The digital section is isolated from the Triac high voltage section using opt isolators.
