Original GE paired PCB board set for Mark VIe gas‑steam turbine control system.

Product Overview

IS200AEPAH1AFD and IS210BPPBH2CAA are matched assembly boards for GE Mark VIe Speedtronic turbine control system. IS200AEPAH1AFD is AEPA analog & discrete I/O board, collects field sensor signals and completes signal conditioning. IS210BPPBH2CAA is BPPB bridge‑processor board, executes local logic processing and IONet bus data forwarding. The two boards cooperate to realize signal acquisition, logic operation and control output for gas turbine, steam turbine and generator unit. Widely used as maintenance spare part for combined‑cycle power plant turbine control cabinets.

Key Features

• IS200AEPAH1AFD: multi‑channel galvanic‑isolated analog and discrete I/O for field sensor signal conditioning
• IS210BPPBH2CAA: on‑board processor for logic calculation and high‑speed IONet bus data forwarding
• Complete on‑board self‑diagnosis, LED status indicators for fast fault location
• Supports simplex / dual / TMR redundant system architecture for high‑availability turbine control
• Conformal‑coated PCB, resists vibration and electromagnetic interference in power‑plant cabinet

• VME‑style rack plug‑in structure, supports hot‑swap field maintenance
