Product Introduction
The IS420UCSCS2A is a high‑integrity dual‑core controller module designed for the GE Mark VIeS / Mark VIe control system series and intended for safety‑critical applications. As an embedded controller, it executes complex control logic, supports redundancy (Simplex, Dual, TMR), interfaces via IONet and other communications, and meets functional safety standards (SIL 2 / SIL 3). It is built for harsh industrial environments—gas and steam turbines, combined‑cycle power plants, wind farms, large industrial drives—where reliability and safety are essential.
