Description
IS420ESWBH3A: Product Overview
The GE IS420ESWBH3A is a 16-port industrial Ethernet IONet switch designed for integration into GE’s Mark VIe and Mark VIeS distributed control systems (DCS). As a critical component of the IONet network architecture, it enables real-time data exchange between DCS controllers, I/O modules, and human-machine interfaces (HMIs) in industrial automation applications—including power generation, chemical processing, and manufacturing.
Role in Automation Systems:
Positioned as the “network backbone” for Mark VIe/VIeS systems, the IS420ESWBH3A performs three primary functions:
-
Connectivity: Links controllers (e.g., GE’s Mark VIe controllers) to I/O modules (e.g., analog/digital I/O boards) and HMIs, ensuring seamless communication across the DCS.
-
Redundancy: Supports simplex, dual, or triple modular redundant (TMR) controller configurations, maintaining network availability even if one controller fails.
-
Signal Integrity: Uses 10/100Base-TX copper ports (RJ45) to transmit data with minimal latency, critical for real-time process control.
Core Functionality:
-
Port Configuration: 16 copper ports (10/100 Mbps, auto-negotiating) for connecting to local devices (e.g., I/O modules, HMIs).
-
IONet Protocol Support: Optimized for GE’s IONet protocol, which prioritizes real-time data transmission for industrial control applications.
-
Flexible Mounting: Can be mounted on DIN rails (standard industrial enclosures) or panel-mounted (perpendicular to the cabinet) using the optional clip 259B2451BVP4.
Platform Benefits (Mark VIe/VIeS Series):
The IS420ESWBH3A leverages GE’s Mark VIe platform, which is renowned for:
-
Reliability: Industrial-grade components and a rugged design ensure 24/7 operation in harsh environments (e.g., high temperature, vibration).
-
Scalability: Supports expansion with additional IONet switches (e.g., IS420ESWBH2A) to accommodate growing network demands.
-
Integration: Seamlessly integrates with GE’s DCS components (e.g., controllers, I/O modules), reducing setup time and effort.

Core Features & Customer Value
1. High-Reliability Connectivity:
The IS420ESWBH3A’s 16 copper ports provide redundant, noise-immune communication for critical DCS components. For example, in a power plant, the copper ports link the turbine controller to local I/O modules—ensuring that process data (e.g., turbine speed, temperature) is transmitted reliably.
2. Flexible Redundancy Support:
Supports simplex, dual, or TMR controller configurations, allowing customers to tailor network availability to their needs. For instance, a chemical plant using dual controllers can use the IS420ESWBH3A to maintain communication even if one controller fails, preventing unplanned downtime.
3. Rugged Industrial Design:
Operates in temperatures from -40°C to +70°C, making it suitable for harsh environments (e.g., steel mills, offshore platforms). The DIN rail or panel mount options simplify installation in crowded control cabinets.
4. Seamless Integration with Mark VIe/VIeS:
Designed specifically for GE’s DCS, the IS420ESWBH3A integrates with existing Mark VIe/VIeS components (e.g., controllers, I/O modules) without requiring custom configuration. This reduces setup time and ensures compatibility with legacy systems.

Typical Applications
The GE IS420ESWBH3A is widely used in industries requiring reliable DCS communication:
-
Power Generation:
-
Connects Mark VIe controllers to turbine I/O modules (e.g., speed sensors, temperature transmitters) in gas/steam turbines.
-
Example: In a combined-cycle power plant, the IS420ESWBH3A links the turbine controller to the DCS, enabling real-time monitoring of turbine performance.
-
-
Chemical Processing:
-
Provides network connectivity for reactor control systems (e.g., temperature, pressure sensors) and actuator (e.g., valve positioners).
-
Example: In a petrochemical refinery, the switch ensures that reactor data is transmitted to the DCS, allowing operators to adjust process parameters in real time.
-
-
Manufacturing:
-
Connects PLCs (e.g., GE’s RX3i) to robotic arms and conveyor systems in automotive assembly lines.
-
Example: In an automotive plant, the IS420ESWBH3A links the PLC to the DCS, enabling synchronized operation of robotic arms and conveyors.
