IG80 is a gigabit managed Ethernet switch module that supports multi-service access. All the signal pins are connected with the baseplate through double row pins (dip-164 row pins with a spacing of 1.27mm) and four positioning holes with a aperture of 2.2mm.The module uses 500Mhz MIPS32 processor and supports a rich layer 2 management protocol.IG80 module based on mature technology and open web standards design, it uses industrial chip that adapt to high and low temperature, strong electromagnetic interference resistance, salt fog resistant, embedded design can maximum earthquake stabilization, can satisfy the demands of industrial field severe working environment, to provide efficient, reliable and fast solution for industrial internet of thing.
