Core Function
- High-Precision Speed Control
Core Function: As an I/O module for the gas turbine control system, this module directly participates in the acquisition, processing, and feedback of speed signals.
Implementation: Receives raw pulse signals from the magnetoresistive sensor and converts them into digital signals for processing by the control system, ensuring speed regulation accuracy of ±0.1%.
- Multi-Channel Signal Processing
Input/Output Capabilities: Supports parallel processing of multiple analog/digital signals, including:
Inputs: Speed sensor signals, temperature/pressure sensor signals
Outputs: Fuel valve control signals, alarm signals
Signal Isolation: Built-in optical isolation technology effectively prevents electromagnetic interference (EMI) from affecting control signals.
- System Redundancy
Dual-Channel Architecture: Utilizing a redundant circuit design, automatic switchover to the backup channel in the event of a failure in the primary channel ensures continuous system operation.
Self-Diagnostic Function: Real-time monitoring of module health status, providing fault code feedback via LED indicators and the digital communication interface (e.g., ERR-201 for signal loss).
