GE IS215UCCCM04A Mark VIe UCCC CompactPCI Controller Module

The GE IS215UCCCM04A is a CompactPCI-based UCCC controller module designed for mission-critical turbine control applications.

It integrates a high-performance embedded processor system, memory architecture, and multiple industrial communication interfaces into a single rugged board. The module is typically used as the central controller in GE Speedtronic Mark VIe systems, where it executes real-time control algorithms for gas turbines, steam turbines, and balance-of-plant (BOP) processes.

The IS215UCCCM04A includes the IS215UCCC processor board and IS200EPMC daughterboard, forming a complete computing assembly. It supports deterministic real-time operation via the QNX Neutrino RTOS, ensuring precise control timing and high system stability.

With multiple Ethernet interfaces, including Unit Data Highway (UDH), Control Data Highway (CDH), and IONet networks, the module enables high-speed communication between operator stations, field devices, and distributed control modules.

Designed for industrial environments, it provides strong resistance to vibration, temperature variation, and electromagnetic interference, making it suitable for continuous 24/7 operation in power plants and heavy industrial facilities.
