The IS420ESWBH3A (ESWB) Rev.D is an IONet industrial switch designed specifically for the GE Speedtronic Mark VIe / Mark VIeS turbine control system. Serving as the core switching hub for the unit control network, it facilitates real-time, deterministic communication between controllers, I/O boards, and excitation modules, acting as a critical networking component for protection and closed-loop control in gas and steam turbines. Built on a Layer 2 switching architecture, it is optimized for IONet real-time control traffic; it supports the buffering and forwarding of multicast and broadcast packets, while isolating port traffic to prevent collisions. The switch features 10/100 Mbps adaptive Ethernet with auto-negotiation for full/half-duplex operation. It handles control, data acquisition, and protection packets—exchanged between Mark VIe controllers and distributed I/O modules (such as the IS210AEAAH2B excitation I/O board)—with low-latency forwarding. This enables the construction of a redundant IONet control network, ensuring the synchronized transmission of turbine control signals.
