Product Overview

IS400UCSBH1ABR2 is a compact real‑time controller module for GE Mark VIe speedtronic platform, designed for gas‑turbine, steam‑turbine and generator‑excitation control applications. It executes turbine‑sequence logic, PID closed‑loop regulation, interlock protection and IONet distributed‑I/O network management. Multiple isolated Ethernet ports separate control‑network traffic, HMI communication and engineering‑tool access. Passive convection cooling eliminates fan‑related failure risk. Supports simplex, duplex and TMR fault‑tolerant configurations for power‑generation safety‑critical control racks. Obsolete turbine‑control spare unit available as refurbished and surplus tested hardware for legacy power‑plant‑control‑system overhaul projectsGE Vernova.
