The DS3800HIMA1B1B – Isolation Board is a General Electric component engineered for use in Mark IV Speedtronic turbine control systems. Its primary function is to isolate control signals from electrical noise and disturbances that may originate from other components or the external environment. This isolation helps preserve data accuracy and ensures the stability and longevity of other connected modules within the turbine control framework.

This board is particularly important in applications requiring high precision and reliability, as it prevents signal degradation and potential system faults caused by voltage spikes or ground loops. The DS3800HIMA1B1B serves as a safeguard, enabling smooth communication between subsystems while maintaining electrical boundaries.

At Evaflux, we understand the importance of operational continuity. That’s why we offer:

• UNUSED units – Original, factory-new boards for installations requiring new hardware

• REBUILT units – Refurbished and rigorously tested to OEM standards, ensuring cost-effective reliability
