The Moxa EDS-305 Series delivers a reliable and economical solution for industrial Ethernet connectivity. Designed for harsh environments, the switches feature 5 10/100BaseT(X) ports with optional fiber uplinks. A built-in relay output alerts engineers of power failures or port disconnections. These unmanaged switches are suitable for hazardous locations and certified to meet ATEX, Class I Div. 2, and IECEx standards. With a wide temperature range and robust mechanical design, they are ideal for deployment in demanding applications such as energy, transportation, oil & gas, and industrial automation.
