Description
GE IS420ESWBH3A – Ethernet IONet Switch Module
GE IS420ESWBH3A is an industrial Ethernet switch module integral to GE’s Mark VIe and Mark VIeS turbine control systems, providing high-speed IONet connectivity for real-time distributed control. This 16-port 10/100Base-TX copper switch facilitates deterministic communication between controllers, I/O packs, and HMIs using redundant ring topologies with sub-10μs latency. It addresses network reliability challenges in gas turbine environments by featuring conformal-coated electronics, dual power inputs, and electromagnetic interference immunity for continuous operation. The GE IS420ESWBH3A mounts on DIN rails with status LEDs, supporting unmanaged plug-and-play deployment in control enclosures.
