POE (Power over Ethernet) is a convenient way to power the RIO-47xxx Pocket PLC.  A power supply is not needed at the RIO installation because the power is delivered over the Ethernet cable.

A network switch with POE-enabled ports is often used to provide POE for the RIO.   Examples of these switches are:

  • Netgear FS116P
  • Netgear GS108P
  • Netgear FS108P
  • Airlink ASW408POE
  • Airlink ASW308P

If a network switch is already in use that does not provide POE, a power injector can provide POE capabilities when installed inline on an existing CAT5 run.  Examples of these devices follow:

  • Linksys WAPPOE12 (injector only)
  • 3COM 3CNJPSE
  • TRENDnet TPE-111GI

Notes:

POE provides power for the RIO only, including the Analog I/O.  Optically isolated digital I/O requires a separate DC bus.

The RIO is 10/100.  Gigabit network hardware comes with a higher price-tag, and is unnecessary on a 10/100 network.
