Description
Product Description
The GE IS415UCVHH1A is a high-performance vibration monitoring module designed for GE Mark VIe turbine control systems, specializing in real-time vibration data acquisition, processing, and protection logic execution for gas/steam turbines and rotating machinery. The GE IS415UCVHH1A features 4-channel vibration input with 24-bit ADC resolution, enabling precise capture of shaft, bearing, and casing vibration signals to detect early mechanical anomalies. Its embedded digital signal processor (DSP) performs real-time FFT analysis and trend monitoring, triggering alarms or shutdowns per API 670 standards to prevent catastrophic failures. The GE IS415UCVHH1A integrates seamlessly with GE’s ControlST software, simplifying configuration, calibration, and diagnostic workflows. The GE IS415UCVHH1A operates reliably in -40°C to +70°C environments with IP20 protection and redundant 24VDC power inputs, ensuring continuous operation in harsh industrial settings. As a core component, the GE IS415UCVHH1A supports hot-swapping and auto-configuration, minimizing downtime during maintenance or module replacement. The GE IS415UCVHH1A’s compact DIN-rail design (176×120×50mm) optimizes panel space while maintaining compatibility with Mark VIe I/O racks for flexible system expansion.
