The GE IS420ESWBH3AX is an Industrial Ethernet Switch Module designed for the Speedtronic™ Mark VIe control system,
serving as a high-performance networking component for mission-critical turbine and industrial automation applications.
1. Key Functions & Features
High-Speed Industrial Networking:
Provides Gigabit Ethernet (10/100/1000 Mbps) switching for real-time data communication between Mark VIe controllers, I/O modules, and plant networks.
Supports IEEE 802.3 Ethernet standards with full-duplex operation for deterministic data transfer.
Enhanced Redundancy & Reliability:
Features dual 24V DC power inputs for continuous operation during power disruptions.
Implements Rapid Spanning Tree Protocol (RSTP) and Parallel Redundancy Protocol (PRP) for fault-tolerant network redundancy.
Secure & Managed Networking:
Supports VLAN (IEEE 802.1Q) for traffic segmentation and IGMP Snooping for multicast optimization.
Includes port security (MAC filtering) and SNMP v3 for secure remote monitoring.
Rugged Industrial Design:
Operates in -40°C to +70°C environments with high resistance to shock, vibration, and EMI.
DIN-rail mountable for easy integration into control cabinets.
2. Applications
Power Generation: Critical for gas/steam turbine control systems (e.g., GE 7HA, 9HA turbines) in power plants.
Oil & Gas/Industrial Automation: Ensures high-availability networking for distributed control systems (DCS).
