GE IS420ESWAH3A IONet Ethernet Switch 8-Port Mark VIe

The GE IS420ESWAH3A is an 8-port IONet Ethernet Switch tailored for GE’s Speedtronic Mark VIe gas turbine control systems, engineered to meet critical infrastructure standards via Achilles-certified controllers and modern Fieldbus technology. As a core component of Mark VIe’s real-time industrial control ecosystem, it features 8 10/100BASE-TX copper RJ45 ports and supports essential Ethernet standards for seamless connectivity.

Built for harsh and hazardous environments, it includes a corrosion-resistant conformal coating and operates across a wide temperature range: -30 to 65°C for normal use, and -40 to 85°C for shipping/storage. It handles 5–95% non-condensing humidity and meets Universal Building Code seismic vibration requirements, ensuring durability in power generation and industrial settings.

With flexible mounting and redundant 18–36V DC diode-OR’d power inputs, it minimizes downtime. Convection cooling works in vertical/horizontal orientations, eliminating the need for fans. Its high reliability is reflected in a Mean Time Between Failure (MTBF) of over 4 million hours at 35°C, critical for mission-critical turbine control.

Key Features
Port & Protocol Support: 8 10/100BASE-TX copper ports no fiber ports, a unique ESWA trait with auto-negotiation for speed and duplex, plus HP-MDIX auto-sensing. Complies with IEEE 802.3/802.3u/802.3x and supports flow control via IEEE pause packets.

Industrial Durability: Conformal coating resists corrosion; operates in -30 to 65°C and withstands seismic vibration and 5–95% non-condensing humidity, ideal for hazardous and harsh industrial environments.

Reliability & Redundancy: Redundant 18–36V DC power inputs prevent power-related outages; MTBF over 4 million hours at 35°C ensures long-term stability for critical control systems.

Diagnostic Visibility: Per-port dual-color LEDs indicate link presence, activity, duplex mode, and speed; a dedicated power LED simplifies status monitoring and troubleshooting.

Flexible Installation: Panel or DIN-rail mounting with easy access to connections; convection cooling works vertically/horizontally for versatile cabinet integration.

Performance & Compatibility: 256 KB buffer and store-and-forward architecture handle continuous multicast/broadcast packets. Backward-compatible with legacy systems, supports IEEE 1588 timing, and enables future network expansion via long-term part availability.
