Product Description

Overview

The GE FANUC IS420UCECH1B is a high-performance UCEC controller developed for the Mark VIe control platform. It manages real-time turbine logic, system coordination, and protection functions across gas turbines, steam turbines, and industrial automation systems. Moreover, it communicates with distributed I/O packs through the Ethernet-based IONet, ensuring deterministic and reliable operation under demanding load conditions.

This controller integrates advanced synchronization through IEEE 1588 PTP, enabling precise timing across multiple control nodes. In addition, its rugged construction and extended temperature capability support continuous operation in harsh industrial environments. Therefore, it delivers dependable performance in safety-critical applications where response time and control accuracy matter.
