Product Description
GE 336A4940LBP46 is an unmanaged industrial Ethernet switch for GE Mark VIe turbine safety control system, engineered for real-time industrial control applications. It adopts store-and-forward switching architecture with built-in soft-start circuit to limit inrush current within 200% of rated operating current. Redundant DC power supply is supported. It works under wide temperature range and supports SFP optical modules with LC connectors for single-mode fiber connection. DIN rail mounting is available, and panel mounting holes are reserved. Plug-and-play without software configuration, it ensures stable data communication for gas turbine and steam turbine control systems. This spare part is widely used for maintenance replacement of power plant DCS and turbine control systems.
