The IS200SPROH1ADD Backup Protection Terminal Board is a field wiring and signal interface module used within GE Mark VIe turbine protection systems. This board serves as a termination interface between field devices and the backup protection control modules, enabling accurate signal conditioning and reliable communication between sensors and the control platform.

The terminal board works closely with turbine protection I/O packs to process key signals such as speed pickup inputs and generator voltage measurements. By providing structured signal routing and protection circuitry, it contributes to maintaining operational safety and system reliability in turbine monitoring environments.

In the Mark VI control structure, the IS200WNPSH1A operates as an auxiliary power supply board that assists the primary power modules in delivering regulated voltage to connected control boards.

The module converts incoming DC power into required negative voltage outputs and distributes them through multiple buffered channels. By maintaining stable voltage levels and minimizing electrical noise, it supports the continuous and accurate operation of turbine control electronics.
