Description
GE IS200STAIS2ACB Mark VI Speedtronic STAI Compact Analog I/O Terminal Board
Product Description
The IS200STAIS2ACB is a compact STAI analog I/O termination board developed for GE Mark VI Speedtronic turbine control systems. It serves as the field wiring interface between analog field instruments and Mark VI I/O packs, handling signal termination, filtering and conditioning for multiple analog input and output signals. Equipped with screw terminal blocks and high-density D-sub connector, it routes conditioned analog signals to the core I/O processing module. The PCB is conformal coated to resist humidity, dust and airborne contaminants inside power plant control cabinets. This DIN-rail mount compact board supports simplex and TMR triple modular redundant configurations, widely used for gas & steam turbine measurement and closed-loop control in power generation facilities.
