GE IS200BPPBH2CAA | Mark VI/VIe BPPB I/O Main Control Sub-Board (BPPBH Series) 

Backside gold pins of the module

I. Model distinction (IS200 bare board / IS210 complete module)

IS200BPPBH2CAA: Bare PCB main control board (CAA coating version), three-proof coating, installed in the metal casing of the IS210BPPBH2CAA complete machine interior

IS210BPPBH2CAA: Complete module set = Metal front frame + Shell + Built-in IS200BPPBH2CAA motherboard, I/O Pack rack slot direct installation

BPPB stands for Base Processor Board, I/O local processing substrate, core computing board for Mark VIe gas turbine / EX2100 excitation I/O module, and MVRA/MVRE acquisition board for compatibility

System attribution

GE Speedtronic Mark VI / Mark VIe heavy-duty gas turbine (6FA/9FA), steam turbine generator + EX2100 excitation control system, TMR triple-redundant main control architecture standard I/O processing board.

Core hardware functions

I/O local processing

Connect to MVRA/MVRE analog acquisition board, complete AD conversion, filtering, engineering quantity conversion, local pre-processing, and then transmitted via IONet/PVME bus to VCM main control card, sharing CPU computing load.

Channel self-diagnosis management

Routine detection of analog quantity breakage, RTD short circuit, power supply abnormality, backplane communication failure, panel fault indicator + ControlST upper software reporting fault code.

Bus communication hub

Built-in dual Ethernet + serial bus: SRTP industrial Ethernet, Genius fieldbus, realize I/O with main control, upper DCS data interaction.

Local protection logical operation

Responsible for ETS emergency trip, overspeed protection, excitation interlock logic pre-operation, meeting SIL power plant safety level design requirements.

Electrical parameters

Power supply: Rack backplane 24VDC ±10%, onboard isolated DC-DC converting 5V core power supply, power consumption ≈11W

Electrical isolation: 1500VAC voltage isolation between signal and backplane power supply, resisting excitation high-power harmonic interference

Operating temperature: -40℃～+70℃, CAA three-proof coating can withstand coastal salt fog, humid condensation working conditions

Size: Bare PCB 225×140mm; Complete machine IS210 specification 178×76×230mm, net weight ≈1.2kg

Structure: Gold pins backplate connection, module supports hot-swappable online replacement, no need to stop the unit for maintenance
