Selection Guide
-
Channel Requirements:
- For higher channel density, consider the IS200STAHH2 (16-channel variant).
- Verify sensor compatibility (e.g., 4-20 mA vs. 0-10 V) with existing systems.
-
Environmental Conditions:
- Choose the IS200STAOH2AAAR variant for radiation-hardened environments (e.g., nuclear plants).
- Ensure proper cooling in high-temperature installations (≥50°C).
-
Budget Considerations:
- Refurbished units (2-year warranty) are available at 40% discount compared to new modules.
- For HART communication support, upgrade to the IS200STAOH2AAAH model.
Installation and Maintenance Tips
-
Installation:
- Use shielded cables and proper grounding to minimize noise.
- Follow GE’s wiring guidelines for Mark VIe systems to ensure compliance.
-
Calibration:
- Factory-calibrated offsets provide ±0.03% accuracy without field adjustment.
- Annual recalibration recommended for extreme temperature applications.
-
Safety:
- Power down the system before module replacement.
- Adhere to NEC Article 430 for motor control center installations.
