Product Overview

The IS420ESWBH1A is a high-availability industrial network switch belonging to the GE Speedtronic Mark VIe control family. As a second-generation hardware release within the ESWB series, this module is purpose-built to facilitate high-speed IONet (Internal Operational Network) communications. It provides the essential infrastructure for real-time data exchange between controllers, I/O modules, and operator interfaces. Engineered for the rigors of power generation and industrial automation, this switch supports mission-critical redundancy, ensuring that control data remains synchronized and accessible even in complex network topologies.

Hardware Architecture and Connectivity Specs

• Copper Interface: Features sixteen 10/100Base-TX RJ45 ports for local device connectivity and diagnostic access.

• Fiber Optic Uplink: Equipped with a single 100Base-FX fiber port utilizing an LC-type connector for long-distance, noise-immune data transmission.

• Controller Redundancy: Architecturally optimized to support Simplex, Dual, and Triple Modular Redundant (TMR) system configurations.

• Mounting Versatility: Supports traditional parallel mounting or perpendicular installation (using the 259B2451BVP4 clip) on standard DIN-rails or panels.

• Network Integrity: Built to meet the stringent latency and throughput requirements of GE Mark VIe UCEC controller clusters.

• Physical Profile: Lightweight 0.22 kg design with a compact 2.1 x 18.6 x 26.3 cm footprint for high-density cabinet integration.

• Standardization: Complies with GEI-100869 industrial Ethernet protocols for seamless integration with Speedtronic hardware.

Strategic Industrial Deployments
