Product Description

Overview

The GE FANUC IS420UCSCH2A is a high-performance Universal Controller developed for the Mark VIe control platform. It delivers deterministic, real-time control for turbines, auxiliary equipment, and safety-critical industrial systems. Moreover, it communicates seamlessly with distributed I/O packs through the Ethernet-based IONet, allowing flexible system designs and fast response times in demanding applications.

The controller is engineered for long-term reliability with conformal coating, dual-core processing capability, and SIL2 safety certification. Therefore, it performs exceptionally well in power generation, petrochemical facilities, and advanced manufacturing environments where consistent control performance is essential.
