ICP Electronics has released the IES-1050RA and IES-1041FRA unmanaged redundant ring ethernet switches, with 5x 10/100Base-T(x) or 4x 10/100Base-T(X) and 1x 100FX ring redundant port.
DIN-rail, panel or wall mountable, the switches feature plug-and-play redundant ring technology (ethernet redundancy protocol) and ORing can protect applications from network interruptions or temporary malfunctions with its fast recovery time of \<10 ms over 250 units of connection.
Both IES-1050R and IES-1041FRA have a rigid IP30 slim-type housing and wide operating temperature ranging from -40 to 70 °C.
The selectable ring ports are controlled by a DIP switch and no software is required to run the redundant rings.
