DS3800NFCD
The DS3800NFCD is a firing circuit board engineered for GE Speedtronic Mark IV turbine control systems, providing 16 independent firing channels for precise triggering of power electronic devices. It supports synchronized pulse generation and timing functions required in turbine and industrial power-control applications. The compact PCB design facilitates internal installation within Mark IV control racks and PLC add-on assemblies. Typical use includes coordinated activation of thyristors and related power switches where stable, repeatable firing accuracy is critical. The board is intended for industrial environments and aligns with the Mark IV architecture for seamless integration. Operating parameters reported for this model indicate a defined temperature range and small form factor suited to dense control enclosures. This listing covers the circuit card only; accessories or external cabling are not included. Verify compatibility with your specific Mark IV configuration and firing interface before deployment to ensure correct channel mapping and interlock behavior.
