Weidmüller's New PoE+ Industrial Ethernet switches for industrial communication applications

Typical PoE enabled connectivity components include WLAN access points, IP telephony and IP cameras. Routing data and power transmissions, in parallel, will considerably reduce wiring costs. All PoE switches are operated from 24 V and supply PoE enabled Ethernet devices with up to 30 W of input power.

This specially designed feature eliminates the need for an additional 48 V power supply module, which is required for most industrial PoE switches. More importantly, the managed-version supports remote on/off and reset control of connected PoE enabled end devices. For example, via SNMP, WEB interface or HMI/SCADA systems in combination with SNMP or OPC. 6-port IEEE 802.3af/at PoE+ managed and unmanaged Ethernet switches boast four integrated IEEE 802.3af/at compliant PoE and Ethernet combo ports. Weidmüller's managed and unmanaged PoE Ethernet switches have extensive international approvals and certificates of conformity such as CE, FCC, UL/cUL Class I Div. 2 / ATEX, DNV / GL.

In order to meet the needs of applications in industrial communications, the PoE switches are available as an unmanaged version in the Basic Line and as a managed version in the Premium Line. Utilising PoE allows power to be transmitted via symmetrical cables utilised to transmit data. Consequently, Weidmüller offers appropriate high-end Ethernet switches, its managed and unmanaged versions facilitating universal deployment of its PoE switches.

Weidmüller's WLAN module, which can be utilised as an access point, client or bridge, has also been designed as a PoE enabled device. This design feature allows parallel routing of data and power transmission reduces wiring costs considerably. Weidmüller's comprehensive programme of passive Industrial Ethernet components includes the right connectors and connecting cables to fulfil PoE cabling specifications.

Weidmüller's managed and unmanaged PoE switches are fully compatible with the current PoE standard (802.3af) as well as the future PoE+ specification (802.3at, 30 W): thanks to increased power rating of 30 W per PoE port it is also possible to operate end devices that require a power input exceeding 15 W. By utilizing Weidmüller's PRO-M and PRO-H power supplies and corresponding diode modules it is possible to implement a simple redundant power supply solution for applications that demand high levels of availability.
