Description
Product Overview
GE IS200BPPBH2CAA (BPPB) is the BOP (Balance of Plant) processor board for GE Speedtronic Mark VI / Mark VIe gas & steam turbine control systems. It executes auxiliary plant control logic, analog signal acquisition processing, interlock and alarm handling for balance-of-plant equipment including lube oil systems, cooling water, drains and auxiliary valves. It communicates with the main turbine controller and field terminal boards to monitor auxiliary equipment status and execute plant auxiliary protection sequences. Widely used in combined cycle power plants, gas turbine and steam turbine facilities, it is a critical legacy spare for maintenance and retrofit of Mark VI/Mark VIe turbine control racks.
