PoE devices are ideal for industrial applications

Power over Ethernet (PoE) technology brings power, as well as data transfer, to devices via standard twisted-pair Ethernet cabling in a network.

In effect, PoE provides a new standards-based method for power sourcing equipment to provide power to a wide variety of powered devices (PDs) in areas where it is physically or financially prohibitive to offer AC power. The cost savings and reliability improvements associated with not having to install and maintain power wiring in addition to Ethernet cabling, especially in remote locations, provide the incentive for many industrial, utility and infrastructure/buildings contractors to immediately evaluate this technology. Korenix, an emerging manufacturer of Ethernet connectivity devices based in Taiwan, has just launched a new range of innovative, reliable, cost effective PoE devices, available through UK distributor M.A.C Solutions UK. The JetNet 4706 is an industrial managed, dual-mode PoE power sourcing switch. The device is a six-port Fast Ethernet Industrial Managed Switch, with four 10/100TX ports (PoE injectors) and two 10/100TX uplink ports and unique dual mode 24V and 48V DC power source capability. JetNet 4706 complies with IEEE802.3af and the pre-standard for PoE High Power IEEE802.3at. This Power over Ethernet standard can now provide up to 30W PoE high power. But what makes the device stand out from the crowd is that it caters for both standard and non-standard power source systems. It is equipped with a dual-mode PoE power mechanism, for 24V or 48V DC, which means the device can detect different input power voltages, enabling it to automatically perform power device detection, classification, powering and disconnection processes. Also, because of its dual mode capability, the JetNet 4706 is ideal for applications where there is no access to a 48V DC power source. This means adoption is likely to be very high in the transportation (vehicle, aviation and other public transport) sectors where access to a 24V DC power supply is standard.
