The PoE splitter provides data and power over a single Ethernet cable to devices that do not support Power over Ethernet. Simply connect the splitter input cable to a PoE switch or PoE injector and the output cable to a non-PoE network device, such as an access point, IP phone, or IP camera, to provide electricity and data. The expander is self-powered by PoE, meaning no additional power is required. Output voltages can be set to 12V or 24V via dip switch. This splitter extends your network where you want to install network devices for which no power outlet is available.
