Part of GE’s Mark VIe Speedtronic platform for industrial control and automation systems.
Key Features
- Military-Grade Resilience: Conformal-coated PCB for humidity/dust resistance (IP40 equivalent).
- Deterministic Performance: Hardware-based QoS prioritizes control traffic (e.g., GOOSE/SV messages).
- Zero-Packet-Loss Redundancy: HSR/PRP support for <1ms failover.
- Precision Timing: IEEE 1588 PTPv2 grandmaster clock synchronization (±100ns accuracy).
- Cybersecurity: Port security, MAC filtering, and VLAN segmentation.
- Hot-Swappable: Tool-less installation in Mark VIe carrier (e.g., IC693CHS397).
Function/Role
- Creates fault-tolerant Ethernet networks within Mark VIe control racks.
- Synchronizes time-sensitive data across controllers, protective relays, and HMIs.
- Segments critical traffic (e.g., turbine control vs. SCADA) via VLANs.
Purpose/Use
- Control Network Backbone: Connects Mark VIe controllers in redundant ring topologies.
- Deterministic Communication: Ensures real-time delivery of protection commands.
- Legacy Integration: Bridges serial-to-Ethernet devices via protocol conversion.
- Cyber-Physical Security: Enforces network segmentation for OT environments.
Application Fields
- Power Generation:
- Turbine control networks (gas/steam/hydro)
- Plant-wide DCS integration (Modbus TCP/OPC UA)
- Wind farm communication backbone
- Oil & Gas:
- Compressor station control rings
- Drilling rig safety system networking
- Grid Infrastructure:
- Substation automation (IEC 61850-9-2LE, GOOSE)
- Phasor Measurement Unit (PMU) data aggregation
- Industrial Manufacturing:
- High-speed motion control networks
- Process safety system (SIL 3) communication
- Transportation:
- Railway signaling systems
- Shipboard integrated power management
The IS420ESWBH3A delivers carrier-grade networking for GE’s Mark VIe systems, enabling microsecond-level synchronization and zero-downtime redundancy in mission-critical applications like turbine protection and grid stability control.
