The Industrial
Automation Group of Advantech introduces the EKI-2701PSI Industrial
Power over Ethernet (PoE) splitter, which offers the convenience
of a single cable to supply both power and data to connected
devices and equipment.
PoE (also
known as IEEE 802.3af) is a relatively new technology to industrial
and plant-floor environments, but has proven itself in commercial
and enterprise applications over the past several years. Using
the unused wires in a 10/100Base-T cable, or by overlaying
power on the data connections, PoE supplies 15.4W of power
at 48VDC.
This technology
is extremely useful for powering network devices and equipment,
where it is inconvenient, expensive, or infeasible to supply
power separately. Connected between a standard Ethernet device
and a PoE powered connection, the EKI-2701PSI operates as
a splitter, separating the PoE connection into
a standard RJ45 Ethernet port and a removable screw terminal
block capable of supplying nearly 13W at 24VDC.
Packaged
in a thin DIN-rail mount chassis, the EKI-2701PSI is ideal
where panel space is limited. It supports both standard 10/100Base-T
and gigabit 1000Base-T connections. It is also ruggedized
for demanding industrial applications, with 4,000 VDC Ethernet
ESD protection, power line surge (EFT) protection of 3,000
VDC, power isolation, and output power short circuit protection.
For maximum uptime, in unattended and remote locations, it
features an extended operating temperature range of -40 to
75° C.
Harry
Forbes of Boston-based ARC Advisory Group notes The
IEEE 802.3af PoE standard was designed to fit VOIP telecom
applications, and 48 VDC device power is a global standard
in telecom. This Advantech product is the first off-the-shelf
solution I have seen for adapting PoE to standard industrial
automation devices, which expect 24 VDC power. This will prove
very useful in manufacturing automation applications.
The EKI-2701PSI
splitter is an ideal means to gain the benefits of PoE with
standard Ethernet devices in harsh industrial environments.
For applications with two or more devices requiring a PoE
power source, the EKI-2525P 5-port industrial Ethernet switch
is a great match.
