Westinghouse 7381A93G05 PCB Circuit Board – DCS Process Control Module | OVATION Platform
Engineering Background: The Westinghouse 7381A93G05 is a printed circuit board assembly engineered for distributed control system (DCS) architectures. Originally developed under Westinghouse’s industrial automation division—now carried forward through Emerson’s OVATION and legacy Westinghouse DCS lineage—this board serves as a critical signal-processing and logic-execution component within process control cabinets across power generation, petrochemical, and heavy manufacturing facilities.
Product Positioning: Designed for procurement engineers and maintenance teams requiring a verified, drop-in replacement for aging DCS infrastructure. The 7381A93G05 eliminates the need for costly system redesigns by maintaining full backward compatibility with existing backplane and I/O wiring configurations.

System Architecture & Signal Flow
The 7381A93G05 PCB interfaces directly with the DCS backplane bus, receiving process variable signals from field I/O termination assemblies. Onboard logic circuits condition, convert, and route signals to the controller processor module. The board supports both analog and discrete signal paths typical of Westinghouse WDPF cabinet configurations. Proper seating in the designated card slot ensures full bus communication without additional configuration.
