GE IS200VCMIH1B IS200VCMIH1BCB Communication Interface Board

GE IS200VCMIH1B (with IS200VCMIH1BCB as a variant) is a high-performance VME communication interface 

board designed for the GE Mark VI Speedtronic turbine control system. It serves as a VCMI (VME Communication Interface) 

bus master controller, responsible for high-speed data transmission between the VME backplane and I/O modules, protection modules, 

and the main processor. It supports IONet (IEEE 1588) protocol and is widely used in gas, steam, 

and wind turbine control systems for power generation and heavy industrial applications.
