GE IS420UCSCH2A-C-VO.1-A Standalone Controller Module in stock

GE IS420UCSCH2A-C-VO.1-A is a UCSC universal standalone controller for GE Speedtronic Mark VIe / Mark VIeS turbine control system. It adopts dual-core processor with QNX real-time operating system, responsible for deterministic execution of turbine control, protection and BoP logic, and communicates with distributed I/O packs via high-speed IONet network.

This version C-VO.1-A is a special configured firmware variant, supporting IEEE1588 precise time synchronization, redundant Ethernet communication and hot diagnostics. It is fanless passive cooling design, widely used for gas turbine, steam turbine and generator control, and is the core spare part for power plant Mark VIe control cabinet upgrade and maintenance.
