The UCSC Quad-Core Independent Controller Module is a high-performance controller designed for the GE Mark VIe control system. It operates as a fully independent controller with no onboard application I/O, executing complex real-time control logic and communicating with distributed I/O modules through the IONet industrial Ethernet network.

With a quad-core processor, large memory capacity, and multi-Ethernet communication architecture, UCSC is optimized for large-scale units, complex control algorithms, high I/O density systems, and advanced data integration, including cloud connectivity.
