Description
Product Overview
The GE IS415UCVHH1A is a VME-based controller board designed for critical applications in gas turbine, steam turbine, and power generation systems. As part of GE’s Mark VIe Speedtronic control platform, it executes turbine control algorithms, manages I/O interfaces, and ensures real-time operational stability in harsh industrial environments.
Role in Automation Systems:
-
Acts as the primary control module in Mark VIe systems, processing turbine performance data (e.g., speed, temperature) and executing protection logic.
-
Interfaces with turbine I/O boards via the VME bus to monitor sensors and drive actuators.
Core Functionality:
-
Control Logic Execution: Runs QNX-based turbine control software for tasks like combustion optimization and load management.
-
Data Acquisition: Processes analog/digital signals from field devices (e.g., pressure transducers, vibration sensors).
-
Redundancy Support: Enables simplex, dual, or triple-redundant configurations for fault tolerance.
Platform Integration:
-
Compatible with GE’s VCMI communication cards for synchronization and data exchange.
-
Supports Modbus TCP/IP, DNP3, and Profibus protocols for cross-vendor system integration.
