GE IS420UCSBH4A UCSB Controller Module
Product Details:
The GE IS420UCSBH4A is a UCSB Controller Module part of the Mark VIe Series, designed for gas turbine control systems. Equipped with a 1066 MHz Intel EP80579 microprocessor, it operates on the QNX Neutrino real-time, multitasking OS, optimized for industrial speed and reliability. As a standalone controller, it executes application code without hosting application I/O, instead accessing all input data via connected I/O networks. Its hardware and software architecture ensures no single application input is lost during maintenance or repairs. It integrates with Safety I/O modules to implement functional safety loops, achieving SIL 2 and 3 capabilities, and is IEC 61508-certified, making it ideal for safety-instrumented system applications in critical turbine operations.
Key Features:
Performance & Safety: 1066 MHz Intel processor with QNX OS; supports SIL 2/3 safety loops and IEC 61508 certification for risk reduction in critical functions.
Design Advantages: Single-module form factor with built-in power supply; no jumper settings, batteries, or fans; compact panel footprint and easily updatable flash memory.
Connectivity: Communicates via IONet, a private Ethernet supporting only Mark controls I/O modules and controllers, ensuring secure data exchange with I/O packs.
Software Flexibility: Pre-loaded with custom software; runs rungs/blocks and allows minor online control logic modifications without system restart.
Synchronization & Redundancy: Uses IEEE 1588 protocol to synchronize I/O pack and controller clocks within 100 microseconds via R, S, T IONets. Supports dual and Triple Modular Redundant systems, transmitting initialization data, internal states, and synchronization status across controllers.
Installation & Diagnostics: Mounts directly to panel sheet metal with unobstructed vertical airflow. Boot LED provides visual diagnostics—solid during normal boot, 1 Hz blinking for errors; runtime firmware issues trigger continuous blinking. ToolboxST app aids troubleshooting via Ethernet after IP configuration.
