The GE IS420ESWBH1A is the second‑generation ESWB‑series IONet Ethernet switch designed for Mark VIe control systems. It provides high‑speed 10/100Base‑TX networking with expanded copper port density and a single LC‑type fiber port for long‑distance communication. Its rugged industrial design ensures stable operation in demanding DCS environments.
Core Features
The IS420ESWBH1A offers sixteen RJ45 copper ports and one 100Base‑FX fiber port, making it one of the highest‑density ESWB models. It supports simplex, dual, and TMR controller redundancy and can be mounted parallel or perpendicular to the rail, with DIN‑rail and panel‑mount options for flexible installation.
