The IS200TRPAH1A IS200TRPAH1AFB functions as a terminal relay board for turbine systems. This printed circuit board belongs to the Mark VI Speedtronic series from General Electric. The IS200TRPAH1A serves as the base version for relay output management. Its variant, the IS200TRPAH1AFB, includes a conformal coating for enhanced circuit protection. Both boards handle relay switching for steam and gas turbine controls.
Core Technical Specifications
This board features sixteen relay output channels for field device control. You will also find screw terminal connectors for easy wiring access. The board stores no significant energy but uses capacitors for contact debouncing. Meanwhile, the backplane connector handles all power and signal transfers.
