IS200TRLYS1BGG GE Module Parts Mark VI Relay Output Terminal Board
The GE IS200TRLYS1BGG is a relay output and discrete I/O terminal board designed for the GE Mark VI SPEEDTRONIC turbine control system. It is used in industrial turbine control applications to switch external field devices and execute relay-based control, alarm, and protection commands.
The board features plug-in magnetic relays with Form-C contacts and integrated coil-current diagnostic functionality. It provides an electrical interface between the turbine control system and external devices such as solenoids, alarms, interlocks, and auxiliary relays.
The IS200TRLYS1BGG is commonly used in gas turbine and steam turbine control cabinets, where reliable relay switching and equipment protection are essential.
It is important to distinguish this Mark VI board from similarly named Mark VIeS TRLY terminal boards, which have different hardware architectures and specifications.
