eI/O Power Connection
eI/O standard units are powered from a 9-30VDC
source using the screw terminals on the side of
the unit. Sealevel offers several power supply choices to make connection easy (see the Optional Items
section in the beginning of this document).
DC supply wiring must be made in accordance to all local and national electrical codes. In particular,
DC supply wiring must include overcurrent protection which limits the maximum fault current to 8A.
The eI/O PoE units are Class 0 (IEEE 802.3af-2003) Power over Ethernet devices. This allows power and
data to be transferred over a single CAT5 cable and eliminates the need for an external power supply. With
PoE, power can be supplied by power sourcing equipment including PoE switches (midspans) and injectors.
