Description
Product Description
The IC693NIU004 is a high-performance Ethernet Network Interface Unit (NIU) designed for the GE Fanuc Series 90‑30 PLC family. It functions as an Ethernet Global Data (EGD) station, enabling fast, reliable data transfer between PLCs and remote I/O modules over standard Ethernet networks. Equipped with multiple Ethernet ports, built-in diagnostics, and support for key industrial protocols, the module allows flexible integration into distributed control and automation systems.
