Overview
The GE IS200SRLYH2AAA is a rugged and reliable output board designed to deliver discrete control signals to external devices in turbine and process control systems. It is part of the Mark VI Speedtronic platform and is typically deployed in simplex configurations requiring high-speed relay actuation.
Moreover, the board features 12 Form-C electromechanical relay circuits, each with isolated contacts capable of switching both AC and DC loads. The relays are distributed across 48 customer terminals, providing flexible wiring and easy integration into control cabinets. In addition, the IS200SRLYH2AAA connects to I/O packs such as PDOA or YDOA, which handle signal processing and communication with the controller.
Its compact, panel-mounted design and industrial-grade construction make it ideal for power generation, oil & gas, and marine automation applications where durability and reliability are critical.
