IS420ESWBH3A | General Electric | 16-Port 10/100 Base Switch

Product Description

High-Performance IONet Connectivity for Mark VIe Systems

The General Electric IS420ESWBH3A is a specialized industrial Ethernet switch designed for the Mark VIe and Mark VIeS Speedtronic control platforms. Functioning as a critical node within the IONet (I/O Network), this module facilitates the deterministic, real-time data exchange required between controllers, I/O packs, and HMIs. The IS420ESWBH3A features a 16-port high-density configuration, optimized for copper-based 10/100 Base-T communication. Unlike standard commercial switches, this unit is engineered to handle the high-traffic demands of turbine safety and control systems, ensuring zero-packet loss for mission-critical synchronization and protection signals.

Engineering for Extreme Industrial Reliability

The IS420ESWBH3A is built to withstand the rigorous environmental conditions of power generation and oil & gas facilities. It supports an extended operating temperature range of -30°C to +65°C, making it suitable for installation in turbine-mounted cabinets where thermal stress is a factor. For maximum system uptime, the module incorporates redundant 24/28 VDC power inputs with internal diode-OR’ing logic; if one power source fails, the switch continues to operate without interruption. Its unmanaged, plug-and-play design eliminates the risk of configuration errors while providing high-level diagnostics via two-color LED indicators for every port.
