The IS420ESWAH1A is a compact, rugged industrial Ethernet switch featuring 8 RJ-45 10/100Base-TX ports and 1 fiber optic port (100Base-FX). This switch is designed by GE to provide high-speed, fault-tolerant network communication in demanding industrial environments such as power plants, refineries, and turbine control systems.

As part of the GE Mark VIe control platform, this switch plays a key role in the IONet architecture — an essential communication network in GE’s distributed control systems. The IS420ESWAH1A ensures seamless and deterministic data exchange between control processors, Human-Machine Interfaces (HMIs), and I/O modules.

Its fiber port enhances network scalability and isolation, offering long-distance communication up to 2 kilometers using multimode fiber. This feature is especially useful in noisy environments where electromagnetic interference (EMI) may affect standard copper connections. The switch’s rugged construction and extended temperature support make it suitable for installation in both control rooms and field environments.

Built with industrial durability, the IS420ESWAH1A supports DIN rail mounting, passive cooling (fanless design), and plug-and-play configuration. It complies with IEEE 802.3, 802.3u, and 802.3x standards and is equipped with broadcast storm protection, auto-negotiation, and link detection.

At Evaflux Private Limited, we offer the IS420ESWAH1A in both unused and refurbished conditions. Every unit is quality-tested and certified for performance and compatibility. With a deep understanding of GE’s control infrastructure, we provide full support for integration, replacements, and system upgrades.

This switch is perfect for companies looking to build redundant Ethernet topologies in critical systems, especially where fiber and copper combinations are required. For those managing turbine automation, process plants, or legacy GE systems, this unit is a reliable, cost-effective solution.
