Basic Information

• Model: IS200TVBAH2ACC

• Material Code: MRP702115

• Brand/Series: GE General Electric, Speedtronic Mark VIe Turbine Control System, IS200 Series Vibration Input Terminal Board (TVBA)

• Core Purpose: A 16-channel TMR (Triple Modular Redundant) vibration signal conditioning & acquisition terminal board, designed exclusively for bearing, shaft and gearbox vibration monitoring and Mechanical Integrity Protection (MIP) of gas/steam turbines and combined-cycle units; core vibration I/O interface module for Mark VIe control systems.

Key Features

1. Multi‑Channel Redundant Acquisition: 16 physical vibration inputs, supporting 8×2 dual‑redundant or 5×3 triple‑redundant + 1 spare TMR architecture to meet safety integrity level (SIL) requirements.

2. Dual Sensor Compatibility:

   • IEPE/ICP Accelerometers: Onboard 2.0mA constant current source, monitors +6 to +12V bias voltage, compatible with industrial vibration acceleration sensors.

   • Magnetic Velocity Sensors: Supports ±10VDC input, compatible with 20–200 mV/mm/s sensitivity.

3. High‑Precision Signal Conditioning: Independent signal chain per channel; programmable anti‑aliasing low‑pass filters (1/3/10 kHz), high‑pass filters (0.5/5 Hz), software‑configurable gain (1×/2×/5×/10×); 24‑bit Σ‑Δ ADC with >110 dB dynamic range, up to 20 kHz sampling per channel, compliant with ISO 10816 / 13373 vibration monitoring standards.

4. Smart Diagnostics & Protection: Real‑time monitoring of sensor open/short circuit, bias anomaly and loop faults; diagnostic data uploaded to ToolboxST via VME64 backplane; configurable multi‑level alarm/trip thresholds; automatic redundant channel switching, runback or emergency shutdown on fault to prevent equipment damage.

5. System Integration: Communicates with Mark VIe controllers (e.g., IS200VCMIH1B) via VME64 backplane bus; fits standard cabinets, hot‑swap capable for maintenance, industrial‑grade high‑reliability design.
