Description

Product Overview

The GE IS420UCSBH4A is a high-performance embedded controller module designed for GE’s Mark VIe Speedtronic Turbine Control System, specializing in real-time control logic execution for mission-critical applications in power generation, oil & gas, and industrial automation. As part of the Mark VIe ecosystem, this controller provides deterministic control for gas/steam turbines, auxiliary systems, and safety-critical processes, ensuring high reliability and fault tolerance .

Powered by a 1066 MHz Intel EP80579 processor (upgraded from the 600 MHz in earlier UCSB models), the GE IS420UCSBH4A delivers 2x faster processing performance for complex control algorithms. It features 256 MB DDR2 ECC RAM, 2 GB NAND flash storage, and runs the QNX Neutrino real-time operating system, enabling sub-millisecond response times and deterministic data handling. The controller communicates with I/O modules via Ionet (a proprietary industrial Ethernet network) and supports IEEE 1588 Precision Time Protocol for clock synchronization across distributed systems, ensuring ±100 µs accuracy .

Featuring a fanless and battery-free design, the controller eliminates moving parts and maintenance requirements, enhancing longevity in harsh environments. Its conformal-coated circuitry and wide temperature range (-30°C to +65°C) enable operation in offshore platforms, desert conditions, and high-vibration settings. The module is ATEX Zone 2 and UL E207685 certified, making it suitable for hazardous locations with explosive gas or dust .
