GE DS200TCTGG1AFF
Overview: The DS200TCTGG1AFF is a medium-format trip board developed by General Electric for the Mark V Speedtronic turbine control system. It serves as a primary safety component that processes trip signals and emergency stop commands, driving protective shutdown of fuel and steam trip solenoids when fault conditions such as overspeed or excessive vibration are detected. Available documentation identifies it as a Simplex Trip Board equipped with 21 plug-in Form-C (SPDT) relays for Mark V gas turbine control systems. Some supplier sources alternatively describe this part number as a thermocouple input terminal board — source documents vary on the exact configuration, so verification against site "As-Built" documentation is strongly recommended.
