Overview
Designed for integration with GE Series 90-30 and related systems, it enables remote I/O communication over Ethernet networks.
Moreover, it allows engineers to deploy field I/O stations without installing a local CPU.
This Network Interface Unit connects remote I/O racks directly to an Ethernet-based control system.
Therefore, it reduces panel complexity while maintaining deterministic industrial communication performance.
System integrators value its reliability in demanding plant floor environments.
