The IS200EMIOH1AEB is an essential component of GE’s EX2000 Series Excitation Control Systems. It serves as the Exciter Main I/O Board, facilitating communication between the control system and various I/O terminal boards such as EPCT, ECTB, EACF, and EXTB. This board mounts in the control rack and processes input and output signals for the excitation control process. Its role includes handling PT and CT signals, contact inputs, output relay drivers, and pilot trip relay drives. Additionally, the board transmits logic-level gate pulse signals to the ESEL board and other connected components in the power conversion cabinet.
