GE IS420ESWAH3A Industrial Ethernet Switch Brand New

Product Description

The GE IS420ESWAH3A is a rugged industrial Ethernet switch engineered specifically for Mark VIe and VIeS turbine control systems. It provides deterministic, real-time communication between controllers, I/O modules, and operator interfaces, ensuring reliable turbine operation even in harsh industrial environments. Moreover, its compact design and robust construction make installation straightforward in control panels with limited space.

This switch supports both copper and optional fiber ports, offering flexible network architecture with redundancy. In addition, IEEE 1588 PTP synchronization guarantees precise timing for critical turbine operations, including overspeed protection and fast interlocks. Its corrosion-resistant coating and wide operating temperature range allow reliable performance in high EMI, humidity, and extreme temperature conditions.
