Product Introduction
The IS210WSVOH1AE is a specialized vibration monitoring input module developed by GE for integration into the Mark VIe and Mark VIeS turbine control systems. Designed for gas and steam turbines, compressors, pumps, and other rotating machinery, this module provides 8 high-precision analog input channels dedicated to acquiring vibration data from velocity sensors and other condition-monitoring transducers.
As a key component of the turbine protection system (TPS), the IS210WSVOH1AE continuously monitors shaft and casing vibration levels, enabling real-time detection of imbalance, misalignment, bearing wear, resonance, and mechanical looseness. It plays a critical role in preventing catastrophic equipment failure by triggering alarms and automatic shutdowns when vibration exceeds safe thresholds.
The module integrates seamlessly with the Mark VIe architecture via the VMEbus backplane and is fully configurable using GE’s ToolboxST software, allowing engineers to set alarm levels, configure input types, and perform calibration and diagnostics.

Core Advantages and Technical Highlights
Dedicated Vibration Monitoring Capability
The IS210WSVOH1AE is purpose-built for condition monitoring and machinery protection. Each of its 8 channels can be independently configured to accept:
- 4–20 mA signalsfrom active or passive velocity sensors
- 0–10 VDC signalsfrom signal conditioners or external transducers
This flexibility allows integration with a wide range of GE and third-party vibration sensors.
High Accuracy and Noise Immunity
With 16-bit resolution and ±0.1% accuracy, the module ensures precise measurement of vibration levels. Each channel is optically isolated at 2500 VAC RMS, providing excellent protection against ground loops, electrical noise, and transient voltages commonly found in industrial environments.
Programmable digital filtering (low-pass, band-pass) further enhances signal integrity by suppressing electrical noise and harmonics.
Integration with Turbine Protection Logic
The IS210WSVOH1AE feeds real-time vibration data to the Mark VIe control processors (e.g., IS200TVPx), where it is used in:
- Bearing vibration monitoring
- Shaft displacement and seismic vibration detection
- Alarm generation (e.g., “High Vibration” warning)
- Trip logic execution (e.g., automatic turbine shutdown)
Alarm and trip setpoints are fully configurable in ToolboxST, supporting both instantaneous and time-averaged thresholds.
Diagnostics and Health Monitoring
The module includes built-in self-diagnostics that monitor:
- Sensor health (open/short circuit)
- Signal out-of-range conditions
- Module internal faults
- Communication status with the processor
Diagnostic data is reported in real time to the Service and Maintenance Board (SAMB, e.g., IS210SAMBH2AA) for logging and analysis.
Hot-Swap and Redundant Ready
The IS210WSVOH1AE supports hot-swap capability, allowing replacement without shutting down the turbine. While typically used in non-redundant configurations, it can be paired with redundant processors and I/O for mission-critical applications.
Typical Application Scenarios
The IS210WSVOH1AE is widely used in:
- Gas and steam turbine control panels
- Combined cycle and co-generation plants
- Compressor stations
- Industrial mechanical drive systems
- Offshore and onshore oil & gas facilities
It is commonly used to monitor:
- Journal bearing vibration(velocity)
- Thrust bearing wear
- Casing/seismic vibration
- Coupling and gearbox condition
Paired with proximity probe modules (e.g., IS210WSPOH1AE), it provides comprehensive shaft and casing vibration monitoring.

Installation Preparation
Before installing the IS210WSVOH1AE:
- Ensure the target chassis (VTUR, VPBC, or AEBI) has a free VME slot.
- Install the correct terminal board:IS210TBSOH1AED.
- Useshielded, twisted-pair cables for sensor wiring.
- Route vibration sensor cables away from AC power and high-energy circuits.
- Verify sensor power supply (if active sensors are used).
- Always wear anESD wrist strap when handling the module.
✅ Note: Calibrate and verify sensor scaling in ToolboxST after installation.
Maintenance Suggestions
- Monitor vibration trends and alarm status usingToolboxST.
- Perform periodic sensor calibration checks during outages.
- Inspect terminal connections for tightness and corrosion.
- Review diagnostic logs for early signs of sensor or module issues.
- Replace only if diagnostics confirm a hardware fault—solid-state design ensures long service life.
