The GE IS420UCSBH1A UCSB Controller Module is a key component of the Mark VIe Control Safety System Series, designed to execute application-specific control logic with precision and reliability. Unlike conventional controllers, it does not directly host I/O but instead communicates through IONet networks, ensuring continuous access to input data—even during maintenance or controller replacement.

Key Features

• High-Performance Processor: 600 MHz Intel EP80579 CPU.
• Robust Memory Architecture:
  • 256 MB DDR2 SDRAM with ECC.
  • Flash-backed SRAM for data retention during outages.
  • 2 GB NAND flash storage for software/configuration.
• Operating System: Runs on QNX Neutrino, a stable RTOS for industrial applications.
• Lightweight & Compact: Only 2.4 lbs, simplifying panel installation.
• Temperature Range: Operates from -30°C to +65°C (-22°F to +149°F).
• Low-Maintenance Design: No fans or batteries required.
• Precise Synchronization: IEEE 1588 protocol ensures <100 μs clock alignment across controllers and I/O packs.

Advantages

• Compact single-module form factor reduces panel space.
• Integrated power supply eliminates the need for external components.
• Flash-based updates for quick and easy firmware upgrades.
• No jumper settings, simplifying setup and commissioning.
• Enhanced reliability by preventing input data loss during shutdowns.

Redundancy Options

• Dual Redundant System:
  • Shares synchronization and status data between two controllers.
  • Maintains initialization and state values seamlessly.
• Triple Modular Redundancy (TMR):
  • Implements voting logic across three controllers.
  • Provides superior fault tolerance for mission-critical applications.

Mounting & Installation

• Designed for direct panel mounting.
• Requires unobstructed vertical airflow through cooling fins to prevent overheating.

Specifications

Communication

• IONet: A private Ethernet network designed for Mark VIe systems.
  • Provides secure, high-speed communication between controllers and I/O packs.
  • Ensures real-time control and reliable data transfer in demanding industrial environments.
