Product Description
GE IS230SNIDH1A is a Serial Network Interface Board for GE Mark VIe control system, a core communication component of turbine control platform. This board handles high-speed serial network data exchange between controllers and remote I/O or other controllers, realizing communication forwarding and signal exchange on Mark VIe control network. It supports redundant network architecture with channel fault diagnosis and disconnection detection. Rack pluggable design, cooperating with Mark VIe main CPU modules via backplane bus. Widely used for gas turbine, steam turbine and generator set controls. OEM production is discontinued and it is available as spare parts for legacy power plant turbine control systems.
