Key Features & Performance
- Accepts 20 analog inputs and controls 4 analog outputs for comprehensive I/O handling.
- Supports both simplex and TMR configurations, allowing flexibility in system design.
- Includes signal conditioning, analog MUX, A/D converter, and D/A converter for accurate signal conversion.
- Noise suppression circuitry protects against surge and high-frequency interference.
- Firmware includes gas turbine compressor stall detection executed at 200 Hz for enhanced safety.
- Front panel LEDs provide status indication: flashing green for RUN, solid red for FAIL, and steady orange for diagnostic alarm.
Applications
The IS200VAICH1C is commonly deployed in:
- Gas turbine control systems requiring reliable analog signal processing.
- Steam turbine monitoring and control applications.
- Industrial processes that demand high-availability I/O with TMR redundancy.
- Legacy Mark VI system upgrades or replacements where OEM support is no longer available.
Installation Guide
Proper installation ensures optimal performance. Follow these steps:
- Power down the VME processor rack.
- Slide the board into the rack, pushing the top and bottom levers to seat the edge connectors securely.
- Tighten the captive screws at the top and bottom of the front panel.
Always consult the original GE manuals (e.g., GEH-6421) for detailed handling and safety procedures.
Maintenance & Reliability
To maximize service life, periodically inspect the board for dust accumulation and ensure proper airflow within the rack. The conformal coating protects against moisture and contaminants, but routine checks of terminal connections are recommended. With proactive maintenance, this module provides reliable operation in critical applications.
Compatibility & Integration
The IS200VAICH1C works with terminal boards such as TBAIH1B (or earlier) and TBAIH1C (or later), as well as all revisions of DTAI and STAI terminal boards. It communicates over the VME backplane with the VCMI board and controller. This flexibility simplifies integration into existing Mark VI systems.
Selection Guide
Before purchasing, verify your system's revision requirements. The IS200VAICH1C is the C-rated revision of the VAIC board and is suitable for original VAIC generation systems. For higher load resistance applications, consider newer revisions like VAICH1D. PLC Source PRO offers this module in stock, ready to ship, ensuring minimal downtime for your operations.
