GE IS215UCCCS05A Mark VIeS Safety Controller Board

Product Overview

The IS215UCCCS05A is a safety controller board specifically designed for GE Speedtronic Mark VIeS turbine control systems, engineered to execute safety instrumented functions (SIFs) in compliance with IEC 61508 SIL 3 standards. It serves as the core processing unit for safety-critical logic in turbine protection systems, managing emergency shutdown (ESD), overspeed protection, and flame monitoring with redundant hardware and deterministic processing. The board integrates dual-core safety microcontrollers, isolated I/O interfaces, and built-in diagnostics to ensure fault tolerance and reliable operation in harsh industrial environments, such as gas/steam turbine enclosures and power plant control rooms. It operates on 24 VDC power, features conformal coating for environmental protection, and supports seamless integration with Mark VIeS I/O modules and communication networks via ToolboxST software for configuration and monitoring.
