GE IS420UCSBH1A

Technical Specifications

Function Features

• Deterministic Control Logic Execution: 600 MHz Intel EP80579 processor and QNX Neutrino RTOS deliver sub-millisecond response times for real-time control applications, ensuring precise turbine speed, temperature, and load regulation.
• IEEE 1588 Time Synchronization: Synchronizes distributed I/O modules and controllers to within 100 microseconds via IONet, enabling coordinated operation of multiple control components in large-scale systems.
• IONet Communication: 3 dedicated IONet ports (R, S, T) provide high-speed, deterministic data transfer to I/O modules, eliminating single points of failure and supporting distributed control architectures.
• Convection Cooling Design: No internal fans or batteries reduce maintenance requirements and improve reliability in harsh industrial environments.
• Redundant Power Inputs: Dual 24/28 VDC inputs (18–36 VDC range) with overvoltage/undervoltage protection ensure continuous operation during power source failures.
• Hot-Swap Capability: Supports hot-swappable replacement without system shutdown, minimizing downtime during maintenance.
• ControlST Integration: Works with ControlST software for intuitive configuration, monitoring, and diagnostics, including real-time status checks and fault alerts.
• Harsh Environment Protection: Conformal-coated PCB and wide operating temperature range (-40°C to +70°C) protect against moisture, dust, and vibration in industrial settings.
• Hazardous Location Compliance: UL Class I Division II and ATEX Zone 2 certifications enable safe operation in explosive atmospheres.
• Simplex/TMR Compatibility: Designed for simplex operation, with seamless integration into TMR systems for enhanced availability in mission-critical applications.

Application Scenarios

• Gas Turbine Control: Executes control logic for aeroderivative/heavy-duty gas turbines, including speed regulation, combustion control, and load management, ensuring efficient and reliable operation.
• Steam Turbine Control: Manages steam turbine speed, pressure, and valve positions in thermal power plants, optimizing energy conversion and reducing emissions.
• Combined-Cycle Power Plants: Coordinates gas/steam turbine operation, balance-of-plant systems, and plant DCS for integrated control and performance monitoring.
• Industrial Automation: Controls PLCs, sensors, and actuators in refineries, chemical plants, and offshore platforms, supporting harsh environment operation and hazardous location compliance.
• Mark VIe System Expansion: Extends Mark VIe control capabilities to remote I/O racks, enabling distributed control with low-latency data transmission.
• Turbine Retrofits: Direct replacement for legacy controllers in Mark VIe upgrades, enhancing control precision and diagnostic capabilities without requiring system reconfiguration.
• Real-Time Data Acquisition: Supports high-speed data processing for condition monitoring systems, enabling predictive maintenance and reducing unplanned downtime.
• Non-Safety-Critical Control Loops: Ideal for simplex control applications where cost-effectiveness and reliability are prioritized, such as auxiliary system control in power plants.

Compatibility and Integration

• Mark VIe Ecosystem: Fully compatible with Mark VIe/VIeS I/O modules (e.g., IS420PUAAH1A, IS420ESWBH1A), terminal boards, and network switches, ensuring seamless IONet communication.
• IONet Architecture: Optimized for Mark VIe IONet protocol, providing deterministic data transfer for real-time control applications.
• ControlST Software: Configured and monitored via ControlST V07.02.00C or later, supporting logic programming, I/O mapping, and diagnostic alerts.
• Redundant Power Supplies: Works with dual 24/28 VDC power sources (e.g., IS230JPDGH1B) to maximize system availability.
• Documentation: Detailed guidelines available in the GE Mark VIe System Manual (GEH-6725) and ControlST Configuration Guide, including installation instructions and wiring diagrams.
