The Emerson Automation IC200EBI001 is a Network Interface Unit (NIU) from the VersaMax PLC series, originally developed by GE Fanuc. Designed to operate as an Ethernet slave module, it manages and controls I/O modules to establish an efficient distributed I/O architecture within automation systems. The unit features a single RJ45 Ethernet port supporting 10/100 Mbps transmission with auto-negotiation capability, ensuring reliable and flexible network communication. It accommodates up to 1024 bytes of total I/O data—512 bytes for input and 512 bytes for output—allowing seamless data exchange between controllers and field devices. Additionally, the IC200EBI001 supports the installation of up to 64 I/O modules and 7 expansion racks, making it ideal for scalable and high-performance distributed control systems. This NIU could potentially be applied across North America, Europe, Asia, and other industrial regions where Emerson VersaMax PLCs are deployed for Ethernet-based, modular automation solutions.
