The IS420UCSCH2A is a stand-alone, dual-core controller manufactured by GE Vernova for the Mark VIe control system. This module is designed to run application-specific control system logic for high-reliability turbine control and Distributed Control System (DCS) applications in gas, steam, and combined-cycle power plants. The IS420UCSCH2A utilizes a real-time, multi-tasking QNX Neutrino operating system to deliver deterministic execution of critical application code. Unlike traditional controllers that host local I/O on a backplane, this unit communicates with distributed I/O packs across a dedicated, high-speed Ethernet network known as the IONet, ensuring zero loss of single-point application inputs during individual unit maintenance or repair.
