WOODWARD 5484-803 MicroNet CPU Processor Module

Product Brief Description

Woodward 5484-803 is the main CPU processor board for MicroNet turbomachinery control systems. It executes the core control logic, speed governing, protection sequencing and interlock calculations for turbines and compressors. The module communicates with chassis I/O boards through the high-speed backplane and supports multiple communication links for HMI and DCS interface. It is a rack plug-in card used in MicroNet chassis, widely stocked as spare part for industrial prime mover control cabinet maintenance and retrofits.
