The IS200VCMIH2BEE was designed by General Electric as part of its Speedtronic Mark VI control system for industrial gas and steam turbines.

This version of the Speedtronic system is commonly used in processing plants and power generation applications to control turbine speed during start-up, synchronize generators, provide turbine load control, and prevent load loss and turbine overspeed situations.

The IS200VCMIH2BEE is part of the Unit Data Highway (UDH). It is used as the main communication controller board. Data is read and transmitted to other boards via Fiber Optic Ethernet (IONet).

VCMI boards can be designed for simplex or TMR (Triple modular redundancy) applications. The Simplex board has one IONet port, while the TMR board will have three. The IS200VCMIH2BEE board is a TMR board.

IS200VCMIH2BEE uses SIFT voting (software-implemented fault tolerance). The data is broadcast to all remote racks in one packet. The VCMI boards in these remote locations extract the corresponding packet data.

The IS200VCMIH2BEE is dual panel. The back of the circuit board is mainly equipped with resistors and capacitors. The front of the board is more complex and includes connector ports (including two backplanes), inductors/chokes, tp test points, and integrated circuits. The connected front panel has three IONet ports and a public serial port. It has a reset button, two setting screws, and four sets of LED indicators (one set of three, one set of six, one set of eight, and another set of three). The panel is also marked with the company logo and board number.
