Managed ethernet switch for mission critical apps
Ethernet Direct has annouced its Managed Industrial Ethernet Switch, HME-800, HME-621 and HME-623 Series for mission-critical applications.
It offers a 12-48V DC redundant powers input design and is secured with Power Polarity Reverse protection and an Overload Current Reset-table Fuse.
The IP-30 housing protection, wide operating temperature of -10 to +70 deg C and DIN rail mounting makes CUE-500 suitable for an industrial environment.
The E version extends the temperature rating to -40 to +80 deg C.
Power over Ethernet (PoE) has been standardized with IEEE standard 802.3af describing Ethernet power-sourcing equipment and powered terminals.
This specification describes delivering 48V of DC power over unshielded twisted-pair wiring.
Nowadays, more and more Industrial applications are starting to benefit from electrical power sent over Ethernet cables.
This avoids a separate power cord for things like internet phones and wireless access points.
The so-called PoE injects power into an Ethernet cable at the source and receives that power at the destination.
Both the injector and receiver are embedded into the device.
Features of the Power over Ethernet switch are as follows.
* Comply with IEEE 802.3,IEEE 802.3u,IEEE 802.3X, IEEE 802.3af.
* Provides five 10/100 Mbps Ethernet ports with RJ-45 connector.
* Embedded four ports PoE Injector Function classified as PSE.
* Supplies 15.4W of power per port full load with PoE.
Reliable power design features include the following.
* Supports redundant 12-48V DC power input.
* Supports 4,000V DC Ethernet ESD protection.
* Provides surge (EFT) protection 3,000V DC for power line.
* Overload current reset-table fuse present.
* Power polarity reverse protection present.
