4-Channel PoE Midspan Injector

• Injector to accept input voltage between 7V and 24V (AC or DC)
• Rectifies any input to a known-polarity DC output
• Maximum current 1.5A
• 4 channels for powering up to four devices

The 4-Channel PoE Midspan Injector accepts an input voltage between 7V and 24V, either AC or DC, and rectifies it to DC before injecting it onto the spare pairs in the network cable that are not used by 10/100base-T Ethernet. DC+ is connected to Ethernet pins 4 and 5, while DC- is connected to Ethernet pins 7 and 8. Power is only injected "downstream" to devices connected to your network segments: it is not connected back to your Ethernet switch, which is isolated from pins 4, 5, 7, and 8 inside the Midspan Injector to prevent any damage to upstream network equipment.
