Description

The IS420ESWAH1A is an unmanaged industrial Ethernet switch from GE‘s Mark VIe Speedtronic series, forming the backbone of the IONet (Internal Operating Network). The IS420ESWAH1A provides eight 10/100Base‑TX copper RJ45 ports and one 100Base‑FX multi‑mode fiber LC port for extended, noise‑immune uplinks. Designed specifically for real‑time distributed control, the IS420ESWAH1A requires no configuration — it is pre‑optimised by GE to handle the specific multicast and real‑time traffic profiles of turbine control systems. With dual‑redundant 24/28 V DC power inputs, a wide –40°C to +70°C operating temperature range, and full hazardous location certification, the IS420ESWAH1A delivers deterministic, low‑latency switching for safety‑critical power generation environments.

Applications

IONet backbone switching for Mark VIe/VIeS gas and steam turbine control cabinets
Real‑time deterministic network interconnecting UCV controllers, distributed I/O packs (PAIC, PDIA, PDOA, etc.), and local HMIs
Mixed‑media industrial networks requiring short‑haul fiber optic uplinks
Retrofit and upgrade of legacy Mark VI control system network infrastructures
Redundant ring topologies with dual‑network failure protection
Hazardous area installations (Class I, Division 2; ATEX Zone 2) with appropriate enclosure

Features

8 copper + 1 fiber port density: Eight 10/100Base‑TX RJ45 ports for device‑level connections plus one 100Base‑FX multi‑mode fiber LC port for long‑distance, EMI‑immune uplinks.
Unmanaged plug‑and‑play operation: Zero configuration, no IP addressing or network management required; pre‑optimised by GE for deterministic real‑time traffic profiles.
Dual‑redundant power inputs: Diode‑OR’d 24/28 V DC inputs with Phoenix Contact connectors; if one power supply fails, the switch continues uninterrupted through the secondary source.
DIN rail mounting with flexible orientation: Mounts in two orientations — parallel (259B2451BVP1) or perpendicular (259B2451BVP2) to the rail; panel mounting also supported.
Store‑and‑forward switching with pause flow control: 256 KB buffer and IEEE 802.3x flow control ensure deterministic packet forwarding without collisions in time‑critical control loops.
4,000 MAC address table: Supports large networks with many connected I/O packs, controllers, and HMI nodes.
Soft‑start inrush current limiting: Limits inrush current to less than 200% of nominal, protecting power supplies during system power‑up.
Wide operating temperature (–40°C to +70°C): Fanless convection cooling and industrial‑grade components ensure continuous operation in unheated turbine enclosures, outdoor cabinets, and high‑vibration environments.
Hazardous location certified (Class I Div 2 / ATEX Zone 2): Suitable for installation in gas zones, refineries, and fuel handling areas when mounted in appropriate enclosures.
Comprehensive LED diagnostics: Per‑port bi‑colour LEDs provide immediate visual feedback for link presence, activity, speed (10/100 Mbps), and duplex status (full/half).
High MTBF (>4 million hours @ 35°C): Industrial‑grade design with no moving parts ensures long service life and minimal maintenance intervention.
Convection cooled (fanless): Eliminates moving parts that can fail in dusty or high‑vibration industrial environments, improving long‑term reliability.
HP‑MDIX auto‑sensing: Automatically detects and corrects for straight‑through or crossover cables on all RJ45 ports, eliminating the need for specialised cabling.

Functions

Switches and buffers real‑time I/O data, controller status, and HMI traffic between connected Mark VIe/VIeS I/O packs, UCV controllers, and HMI stations over the IONet.
Provides a dedicated 100Base‑FX multi‑mode fiber uplink for extended‑distance communication up to 2 km (typical) with complete immunity to electromagnetic interference — ideal for remote I/O racks.
Automatically negotiates 10/100 Mbps speed and full/half‑duplex mode on each copper port based on the capabilities of connected field devices, eliminating manual port configuration.
Maintains deterministic data forwarding in mixed‑media networks (copper‑to‑fiber) without requiring external media converters or protocol translation devices.
Performs collision‑free full‑duplex switching across all ports, preventing packet collisions and ensuring deterministic latency for time‑sensitive turbine control loops (e.g., fuel valve modulation, speed regulation).
Delivers real‑time port status and network health information via bi‑colour per‑port LEDs, enabling rapid on‑site troubleshooting without external diagnostic software.
Electrically isolates redundant power inputs via diode‑OR’d architecture; if the primary 28 V DC rail fails or droops, the secondary rail automatically assumes load with no interruption to switch operation.
Provides passive store‑and‑forward packet processing with pause frame flow control, buffering incoming traffic and preventing data loss when downstream ports are congested.
Operates continuously in extreme environments (–40°C to +70°C) with fanless convection cooling, eliminating moving parts that can fail in dusty or vibration‑prone turbine control cabinets.
Accepts dual redundant 24/28 V DC power inputs (range 18–36 V DC) from standard Mark VIe control power distribution boards (JPDS, JPDG, JPDH) or external industrial power supplies.

FAQ

Q1: What is the IS420ESWAH1A used for?
A1: The IS420ESWAH1A is an unmanaged industrial Ethernet switch that serves as the central networking hub for GE Mark VIe/VIeS IONet, connecting controllers, I/O packs, and HMIs in turbine control systems.

Q2: How many ports does the IS420ESWAH1A have?
A2: It has 9 ports total — 8 × 10/100Base‑TX copper RJ45 ports for device‑level connections and 1 × 100Base‑FX multi‑mode fiber LC port for extended‑distance, noise‑immune uplinks.

Q3: Does the IS420ESWAH1A support redundant power inputs?
A3: Yes. The IS420ESWAH1A features two independent 24/28 V DC power inputs (TB1 and TB2) that are diode‑OR’d. If one power supply fails, the switch continues operating from the remaining healthy supply.

Q4: What is the operating temperature range of the IS420ESWAH1A?
A4: The IS420ESWAH1A operates from –40°C to +70°C (–40°F to +158°F) with fanless convection cooling, making it suitable for outdoor turbine enclosures and unheated industrial cabinets in extreme climates.

Q5: Is the IS420ESWAH1A compatible with hazardous location installations?
A5: Yes, the IS420ESWAH1A is certified for UL Class I, Division 2, Groups A‑D and ATEX Zone 2 hazardous (classified) locations when mounted in an appropriate enclosure following local electrical codes.
