Weidmüller IES21, IES31 and IES41 managed ethernet switches

Weidmüller has updated its IES series of industrial ethernet switches. With three ranges to choose from, the series offers a broad choice of fast ethernet or gigabit ethernet managed switches with various port combinations. Users can select from entry level IES21 fast ethernet, IES31 fast ethernet with gigabit uplink, up to IES41 full gigabit ethernet switches. The switches feature ring redundancy with floating master, the latest security features, IGMP snooping and a built-in virtual cable tester.

These managed switches are equipped with Weidmüller’s W-Ring technology, which simplifies network requirements by eliminating master/slave settings in a redundant ring, while providing a network reinstatement time of less than 20 ms. They also feature MSTP for additional redundancy, providing the possibility of spare links that automatically provide backup paths should the active links fail.

The IES managed switches also have a built-in virtual cable tester (VCT). The VCT tests a twisted pair connection status by using time domain reflectometry. It is capable of identifying the type of fault as well as the distance from the switch port within 5 s.
