PRODUCT INFORMATION
Product Overview
The General Electric IS200TTURH1CFD is a Terminal Turbine Board for Mark VI and Mark VIe systems. It operates as a primary turbine protection input terminal board within turbine control architectures. The assembly interfaces with pulse rate devices sensing toothed wheels to track rotational speed. It also processes generator voltage and bus voltage inputs from external potential transformers. Turbine overspeed trip signals pass through this terminal board directly to designated trip boards.
Physical termination relies on two pluggable terminal blocks mounted to the primary circuit board. Two retaining screws secure each pluggable block to simplify routine field servicing. Each individual terminal block accepts twenty-four connections, providing forty-eight total termination points. A dedicated shield ground bar extends along the left edge of the printed circuit board. Factory-drilled mounting holes allow straightforward mechanical installation in standard cabinet positions. A protective conformal coating shields all surface-mount and through-hole components from environmental exposure.
