January 30, 2018 — Wieland Electric Inc. has added three new switches to its wienet series of Ethernet switches: the UMS 5-W, UMS 8 and LMS 16-W.

These new switches have DIN rail mountable metal housing, redundant power supply inputs with fault relay contacts and a -40°C to +75°C temperature range.

Wieland says the UMS 5-W minimizes the footprint in the control panel with a slim 30mm width. Meanwhile the UMS 8 PoE-W switch enables the joint transfer of energy and data as per IEEE 802.3 on one Ethernet line. The switch has four regular ports and four ports that support PoE; up to 15.4W can be supplied per PoE port. Finally, the LMS 16-W uses Modbus TCP to communicate with SCADA systems and can communicate with an NMS (Networking Managmenet System) via SNMP.
