1. Product Overview
The GE IS420UCSCH2A-C-V0.1-A is a hardware version (V0.1-A) of the high-performance dual-core UCSC (Unified Control System Controller) module, engineered as the core processing unit of GE Speedtronic Mark VIe Distributed Control System (DCS) for mission-critical industrial power generation and turbine control. This version features a 1.2 GHz dual-core industrial CPU optimized for V0.1 firmware, 2GB DDR3 SDRAM, 4GB bootable flash memory, and QNX Neutrino Real-Time Operating System (RTOS) for deterministic control logic execution. It supports simplex, dual, and triple modular redundant (TMR) architectures, with dual Gigabit Ethernet ports for IONet/plant network redundancy, ensuring zero-downtime operation in gas/steam turbine, hydroelectric, and oil & gas processing applications. With a -40°C to +70°C operating range, SIL 3 capability (IEC 61508), and rugged industrial design, it delivers reliable 24/7 performance in harsh control environments.
