GE IS200AEADH4ADA Turbine Control I/O Terminal Board Inquiry Item

Details

This GE IS200AEADH4ADA is an I/O signal termination board of Speedtronic Mark VI / Mark VIe turbine control platform. It belongs to Alternative Energy Application D series board, mainly used for grid feedback, excitation monitoring and synchronizing signal wiring termination of gas turbine, steam turbine and generator control system. It integrates analog signal conditioning circuit and discrete signal input channel, collects voltage, current, permissive interlock and status signals from field sensors, then transmits conditioned signals to the main I/O control board through internal harness. The PCB is coated with conformal coating, anti-vibration and anti-salt mist, adapted to the harsh working environment of power plant turbine cabinet. This model is obsolete, it is a common maintenance spare part for old GE turbine control system retrofit and repair.
