Alfa network PD-1000CM passive poe device to standard poe module with surge protection

Alfa Network PD-1000CM Passive PoE Device to Standard PoE Module with Surge Protection&nbsp, &nbsp, PD-1001 802.3af/at 12V Gigabit PoE Module The PD-1001 can be used in numerous applications, in the example shown in Figure above,&nbsp, the data+power outputs from the PoE switch are connected to the each output that supports Power over Ethernet (PoE). In this example port 1 is connected to an ethernet camera and port 2&nbsp, is connected to a wireless access point, both of these devices have a built-in PD-1001. When the&nbsp, PoE Switch is switched on (or when the device is connected), the PoE Switch will check each output for a PoE signature. On ports 1 and 2 the PD-1001 will identify themselves as PoE enabled&nbsp, devices and will supply both data and power to these peripherals. The other ports (shown in this example)&nbsp, will not have a PoE signature and only pass the data through to these peripherals. The PoE Switch will continuously monitor each output to see if a PoE enabled device has been added or removed. &nbsp, &nbsp, Feature : &nbsp, &nbsp,Compliant IEEE802.3af/at PD interface&nbsp,Small SIL package size - 80mm (L) x 16mm (H) &nbsp,Input voltage range 42V to 53V &nbsp,Minimal (low cost) external components required &nbsp,Short-circuit protection &nbsp,1500V isolation (input to output) &nbsp, &nbsp, &nbsp, Specification : &nbsp, Pin No. Name Description 1 VA1 RX Input (1).
