GE IS200VCMIH2C IS200VCMIH2CAA TMR Communication PCB

The IS200VCMIH2C IS200VCMIH2CAA serve as VME communications boards for turbine control. The IS200VCMIH2C functions as the base printed circuit board. Its fully assembled variant, the IS200VCMIH2CAA, includes a conformal coating for circuit protection. Both boards belong to the Mark VI Speedtronic series from General Electric. They manage high-speed data exchange for steam and gas turbine systems.

Core Technical Specifications

These boards support Triple Modular Redundant (TMR) communication protocols. You will find three IONet ports located on the front faceplate. The TMR configuration enables the IS200VCMIH2C IS200VCMIH2CAA to perform SIFT voting for fault tolerance. Therefore, a single board failure will equate to a total control module failure.

Installation and System Integration

Always install the IS200VCMIH2C IS200VCMIH2CAA in the first slot of the VME rack. The board uses the P1 backplane connector for internal data transfer. Meanwhile, the P2 connector communicates with the J3 and J37-pin terminal boards. This design ensures seamless communication between I/O boards and the main controller.
