GE IS420UCSBH1A
- Product Name: Mark VIe UCSB Universal Controller Module
- Product Introduction: A high-performance standalone controller module serving as the core processing unit for GE’s Mark VIe, EX2100e, and LS2100e turbine control and safety platforms. It executes real-time control logic for industrial gas turbines, steam turbines, and generator sets.
Detailed content
- Technical Specifications:
- Processor: 600 MHz Intel EP80579
- Memory: 256 MB DDR2 SDRAM with ECC
- Storage: 2 GB NAND Flash
- Operating System: QNX Neutrino Real-Time OS
- Primary & Secondary Ethernet: 10Base-TX / 100Base-TX RJ-45
- IONet Ports: 3 ports for redundant R/S/T I/O networks
- Supported Protocols: TCP/IP, EGD, Ethernet Modbus, OPC UA, CDH
- Input Voltage: 18–30 V DC (nominal 24/28 V DC)
- Maximum Input Current: 1.5 A DC
- Nominal Power: 15.6 W
- Weight: 1.0 kg
- Operating Temperature: –30 °C to +65 °C (–22 °F to +149 °F)
- Safety Integrity: Suitable for IEC 61508 SIL 2 and SIL 3 applications
- Compliance: UL E207685, ATEX Zone 2 IIC
- Functional Features: Fanless, battery-free, jumper-free design; supports Simplex, Dual, and Triple Modular Redundant (TMR) architectures; deterministic I/O communication over IONet; on-board ECC memory for high reliability.
- Application Scenarios: Core controller for gas turbine speed and temperature control, steam turbine governing, generator excitation control, and balance-of-plant automation in combined-cycle and simple-cycle power plants.
- Working Principle: The module runs application code under QNX Neutrino RTOS, exchanges data with distributed I/O packs via IONet Ethernet, and processes analog/digital signals to drive actuators and protection trips.
- Installation Requirements: Slide into the designated Mark VIe chassis slot, secure the grounding and retention screws to the chassis backplane. Connect dual Ethernet lines to independent network switches (e.g., Ion networks) and ensure physical separation from high-voltage power wiring. Terminate 24 V DC power through a fused terminal strip, keeping input within 18–30 V DC under all load transients.
- Usage Notes: In Simplex configuration, removing the module halts execution and trips the system—only perform hot-swap in redundant or TMR architectures. Observe ESD precautions when handling the module.
