Key Features:
- Universal I/O Flexibility – Software-configurable input/output modes per channel.
- Galvanic Isolation – Prevents ground loops in distributed sensor networks.
- Redundant Power Inputs – Automatic failover with OR-ing diodes.
- Sensor Excitation – Provides 24VDC/10mA for 2-wire transmitters.
- Intrinsic Safety – Supports IS barriers for hazardous areas (Class I Div 2).
- Live Calibration – Field-adjustable zero/span without shutdown.
Primary Function & Purpose:
Converts and isolates analog field signals (e.g., pressure, temperature) to Mark V-compatible levels while eliminating electrical noise, ground loops, and voltage spikes to ensure control system signal integrity.
Typical Applications:
- Turbine Sensor Interfaces – Conditions signals from:
- LVDT (Valve Position)
- Pressure Transmitters (Combustion Monitoring)
- Thermocouples (Exhaust Gas Temp)
- Actuator Control – Drives servo valves, I/P converters.
- Fuel Flow Metering – Isolates pulse outputs from flow computers.
- Vibration Monitoring – Buffers accelerometer signals to analyzers.
Application Fields:
Essential for signal reliability in:
- Power Generation: Gas/steam turbines, HRSGs, balance-of-plant systems.
- Oil & Gas: Compressor control, wellhead pressure monitoring.
- Water Treatment: Pump station control loops.
- Industrial Automation: Critical process skids (e.g., chemical injection).
