Description
GE IS220PHRAH1A
(High-Density Analog Input Module for Turbine Control Systems)
Product Overview
The GE IS220PHRAH1A is a 16-channel analog input module designed for GE’s Mark VIe Speedtronic™ turbine control platform. This module interfaces with sensors (e.g., pressure transducers, thermocouples, RTDs) to monitor critical parameters in gas/steam turbines, compressors, and other industrial machinery. Compliant with IEC 61508 SIL 2 standards, it ensures precise data acquisition for safety and performance optimization in power generation, oil and gas, and heavy industrial applications.
Key Features
- High-Density Inputs: 16 channels configurable for voltage (0–10 VDC), current (4–20 mA), or temperature (RTD/TC) signals.
- Advanced Diagnostics: Continuous health monitoring for open circuits, signal drift, and sensor degradation.
- Redundancy: Supports hot-swappable replacement and dual-module redundancy for fault-tolerant systems.
- Integration: Seamless communication with Mark VIe controllers via VME backplane or Ethernet.
- Software Configuration: Programmable via GE’s ToolboxST™ for scaling, filtering, and alarm thresholds.
