Description
1. Product Description
The IC670ALG230 is a high-performance analog input module designed by GE Fanuc for its PACSystems RX3i platform. Engineered for industrial automation and process control, the IC670ALG230 supports 16-channel analog input (4–20mA, ±10V) with 16-bit resolution and advanced signal conditioning. It features galvanic isolation (2.5kVrms), built-in cold-junction compensation for thermocouples, and configurable alarm thresholds. The module integrates with GE’s Proficy software for seamless system integration, enabling real-time monitoring in harsh environments (e.g., temperature ranges of -40°C to 70°C). Ideal for applications requiring precise data acquisition, the IC670ALG230 ensures reliable operation in power generation, manufacturing, and water treatment systems.

6. Selection Recommendations
- Compatibility: Verify backplane compatibility (RX3i series; avoid legacy VersaMax systems).
- Environment: Match temperature (-40°C to 70°C) and vibration (5–500Hz, 5g) requirements.
- Scalability: Pair with IC670CPUE050 for distributed control in large-scale systems.
7. Precautions
- Installation: Follow GE’s wiring guidelines (separate analog/digital cabling; shielded twisted pairs for thermocouples).
- Calibration: Factory-calibrated (traceable to NIST); recheck every 2 years in high-precision applications.
- Safety: Disconnect power before module replacement; use ESD protection (ESD rating: ±8kV air discharge).
