Product Description
The IS200FCGEH1ADA is a GE component created for the Mark VI system. The Mark VI turbine system is part of the Speedtronic series that has been used for gas and steam turbine management since the 1960s. The Mark VI can be designed to manage large and small turbine setups by using either Simplex or Triple Redundant forms of the control system. Each circuit card in the control module is designed with diagnostics; diagnostics include software diagnostics and hardware diagnostics.
The IS200FCGEH1ADA works within the Mark VI system as an LCI Control and Gating-Exciter card. This board has a front faceplate that includes two openings for access to 28 TP test points. The faceplate also has two LEDs. These LEDs are labeled “active” and “Imok.” The “Imok” LED blinks as an indicator that the board has passed a self-test and is functioning properly. The “Active” LED lights solidly when the board is communicating with the LCI processor board. Test points on the board are labeled “VCSS1 through VCSS7, VCA, VAB, VBC, OFC4 through OFC6, and DCOM, then IFB, IA, IB, IC, VOUT, GVOLTS, EI60Hz, OFC1 through OFC6, and DCOM.
The IS200FCGEH1ADA has several connectors. This includes a P1 VMEbus backplane and a P2 connector for Input/Output interfacing with other LCI boards, the host processor, and with the exciter. The board also has two 20-pin ribbon connectors that are for factory test use only.
More information on the IS200FCGEH1ADA may be found in GE publication GEI-100233. This publication includes procedures and information on firmware, as well as installation instructions.
