RPi PoE Relay Board Module for Raspberry Pi 3B plus 4B

1, Supports Raspberry Pi 3B+ 4B, the RPi Relay Board gives your Pi the ability to control high voltage/high current devices, easily makes normal home appliances become intelligent. And support 802.3af Power-over-Ethernet (PoE) from Raspberry Pi gigabit ethernet port, allows you to power your Raspberry Pi using Power over Ethernet–enabled networks. 2, Power-over-Ethernet (PoE): IEEE802.3af compliant. Support PoE applications in both of Fast / Gigabit Ethernet environments. Fully isolated switched-mode power supply. Support wide input voltage range 37Vdc to 57Vdc. output 5V/2.5A (If you don’t want to use PoE power supply, you can still use the Raspberry Pi USB power supply port to supply 5V power, the PoE circuit will not affect your USB power supply. BUT, you can only choose one of the two, and you cannot connect the two power supply modes at the same time). 3, Subminiature high power relays, loads up to 10Amp 277VAC / 28VDC. One LED for power and three LEDs for relays status indicating. Darlington transistors circuit driving relay, improve the reliability of action. Relay control jumper, allows to control the relays by custom pins other than the default pins 4, Terminal blocks: pitch - 5.0mm/0.197", wire size 26~12 AWG / 1.5mm square, stripping length 5mm/0.2", Metric M2.5 slotted screw. Support 40-pin GPIO expansion connection, pin height 8mm/0.32" 5, Package included: 1x RPi PoE Relay Board, 4x M2.5x16mm nylon standoffs, 4x M2.5x6mm nylon standoffs, 4x M2.5 nylon nuts (NOTE: the item not include Raspberry Pi module).CAD 3D(pdf): https://m.media-amazon.com/images/I/B1f5vrYqpSS.pdf
