Weidmüller switches: Eco Line unmanaged switches for industrial communication applications – switches with maximum port density – optimally adapted to industrial applications

The new Ethernet Switches from Weidmüller have been specifically developed for small industrial networks. They offer secure and reliable communication between Ethernet-based machines and systems as well as allowing for the connection of Ethernet devices to a higher-level network.

The unmanaged Plug-and-Play switches mean that network connections can be directly extended to include multiple devices. The switches with 5 to 24 ports allow users to tap into the benefits offered by standardised Ethernet communication and industrial automation technology.

Depending on the particular version, the switches are fitted with a number of combinable copper or fibre-optic interfaces, meaning that different media can be used and large distances covered. All Ethernet switches have an industrial IP30 metal housing with integrated clip-in foot for easy installation on the terminal rail (TS35). The integrated clip-in foot has been specially optimised for simple installation. The sturdy housing design and the high port density combined with particularly compact dimensions means that the space in the control cabinet can be put to optimal use. This applies in particular to the 5-port switch, one of the smallest switches in terms of density and a switch that is particularly well-suited to the tight spaces in control cabinets. The largest configuration level contains 24 ports.

In addition to its high density, the switch is also characterised by its large temperature range. The switches can be used in environments from –40 to +75 °C. This allows for operation both within production and in the field. In line with the motto "an LED for each port", the integrated LEDs provide a simple display of the speed and status of the port.

Flexible and future-proof with SFP slots

Whether multi-mode or single-mode, 500 metre or anywhere up to 20 km – the SFP slots help guarantee flexible use. SFP stands for Small Form Factor Plug-In, and these slots make it possible to combine network components such as switches with optical cables. This allows them to convert electrical Gigabit signals to optical signals and vice versa. To do so, the matching transceiver simply needs to be plugged in. It is therefore also possible to change the technology at a later point in time.

The wirespeed-compatible switches support auto-negotiation, which is a procedure whereby two connected Ethernet ports automatically determine and configure the maximum possible transmission rate. The integrated auto-crossing function also ensures more simple installation while also preventing error sources as there is no longer any need for crossover cables. The switches with this standard detect the paired transmission and reception lines and automatically and correctly assign the pair internally.

The modules have input current limitation and reverse polarity protection. The Eco Line switches are connected via the removable 3 or 4-pin plug-in connectors. The comprehensive range contains Fast Ethernet and Gigabit variants as well as PoE models with 802.3 af.  Most variants have a redundant power input of 24 VDC. The 5 and 8-port copper models can also be operated with a 24 VAC power supply, making them suitable for use in building automation. Thanks to their international approvals and conformity certificates in accordance with CE and UL, the Ethernet switches are suitable for industrial applications all over the world. The key benefits of the unmanaged switches include their good price-to-performance ratio as well as their particularly space-saving design.
