The IS200TRLYS1BGG is a board component specifically designed for General Electric's Mark VI system, which serves to manage and control industrial gas and steam turbines. As part of the Speedtronic series, it represents a lineage of turbine control systems dating back to the original Mark I system released in the 1960s.
Functionality
The IS200TRLYS1BGG functions as a discrete I/O board within the Mark VI system. It is one of several discrete I/O boards available for the MKVI, including the TBCI, DTCI, TICI, and DRLY. Similar to the TBCI and TICI, it is a barrier-type input/output board featuring plug-in magnetic relays with form C contacts. This particular version of the board is utilized for diagnostics related to coil current, whereas a TRLY board ending in H1C is recommended for diagnostics related to contact voltage.
Features
The IS200TRLYS1BGG is constructed with multiple relays aligned along the board center. One edge of the board features two terminal strips with numbered screw connections, while the other edge is equipped with four d-shell connectors. Additionally, the board includes three three-pin plugs and various other components such as integrated circuits, variable resistors, fuses, resistors, capacitors, and diodes. Components are often marked with the GE logo and carry reference designations for identification. For detailed information, reference manuals and data sheets are available.
