Description
The GE IS215VPROH2BC is a 16-channel voltage input module for GE’s Mark VIe turbine control platform. Designed for precise measurement of generator/stator voltages (0–300V AC), it provides RMS/phasor data to the turbine controller (/) via VME backplane. Features galvanic isolation, harmonic analysis (up to 63rd order), and dual-range autoranging (20V/300V full-scale).
Features
- Voltage Inputs:
- 16× differential channels (bank-configurable)
- Dual-range: 0–20V AC (PT secondaries) or 0–300V AC (direct)
- Autoranging with OV lockout (>350V)
- Signal Processing:
- 24-bit ΔΣ ADC per channel (0.1% accuracy)
- 4-kHz sampling (per phase)
- Harmonic magnitude/phase extraction
- Protection & Diagnostics:
- Channel-wise fuse failure detection
- Overvoltage/undervoltage alarms
- Watchdog timer for DSP health
- Integration:
- VME64x backplane interface
- communication to controller
- Hot-swappable (with carrier)

Key Applications
- Turbine Generator Monitoring:
- Stator voltage sync-check (25/27/59)
- VAR/power factor control
- Overexcitation (24) protection
- Power Quality:
- Voltage unbalance (47) detection
- Sub-synchronous resonance (SSR) analysis
- Grid Compliance:
- IEEE 1547 anti-islanding
- IEC 61000-3-6 harmonic limits
⚠️ Critical Integration Notes:
- PT Connections: Use twisted/shielded pairs (AWG 18 min) – shield grounded ONLY at cabinet.
- Range Selection: Configure via VPRO_SW ToolboxST™ parameter – incorrect setting damages ADC.
- Grounding: Module chassis MUST bond to star ground – noise >2% FS if floating.
- Firmware Dependency: Requires Mark VIe controller ≥R196 or VPHD faults occur.
- Slot Restrictions: Install ONLY in VME slots 2–5 of carrier (slots 1/6 disable channels).
- Harmonic Setup: Enable HARM_OPT=1 in configuration – defaults to RMS-only mode.
- Replacement Procedure: Power down ENTIRE carrier – hot-swap corrupts VME arbitration.
