Description
The Fireye NXDBVSD is a VFD (variable frequency drive) interface daughter board engineered for seamless integration with Fireye NX6100 and PPC6000 burner management systems. By expanding native system capability, it enables precise, coordinated motor control between the burner controller and external variable speed drives — delivering tighter modulation of combustion air, fuel delivery, and auxiliary motors for measurable gains in combustion efficiency and overall system performance.
Built for demanding industrial combustion environments, the NXDBVSD features dual VSD control channels, an analog output for real-time signal feedback, counter inputs for performance monitoring, programmable relays for automated control logic, and isolated RS485 Modbus RTU communication. This combination makes it a highly flexible interface solution for HVAC and boiler applications where coordinated motor control and energy optimization are critical.
