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 48V DC.
The Industrial Automation Group of Advantech has released 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 IEEE802.3af) 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 48V DC.
This technology is extremely useful for powering network devices and equipment, where it is inconvenient, expensive, or unfeasible 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 24V DC.
Packaged in a thin DIN-rail mount chassis, the EKI-2701PSI is suitable for applications where panel space is limited.
It supports both standard 10/100Base-T and gigabit 1000Base-T connections.
It is also ruggedised for demanding industrial applications, with 4000V DC Ethernet ESD protection, power line surge (EFT) protection of 3000 V DC, 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 75C.
Harry Forbes of Boston-based ARC Advisory Group says "The IEEE802.3af PoE standard was designed to fit VOIP telecommunications applications and 48V DC device power is a global standard in telecommunications".
"This Advantech product is the first off the shelf solution I have seen for adapting PoE to standard industrial automation devices, which expect 24 V DC 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.
