Description
Product Overview
The GE IC695ALG412 is a high-precision strain gauge and thermocouple input module designed for GE Fanuc’s PACSystem RX3i platform. It integrates advanced signal conditioning and isolation technology to directly interface with strain gauges, load cells, and various thermocouples (J, K, T, E, R, S, B, N, C types), eliminating the need for external transmitters or signal conditioners. With 12 isolated differential input channels and 32-bit IEEE floating-point resolution, the IC695ALG412 delivers laboratory-grade accuracy (±0.25% full scale) for critical industrial measurements such as stress analysis, weight monitoring, and temperature profiling. As a core component in GE’s RX3i distributed control architecture, this module enhances real-time data integrity in electrically noisy environments like chemical plants and manufacturing lines, supporting predictive maintenance and process optimization.

Key Features and Advantages
Precision Measurement: Utilizes Σ-Delta ADC technology with 32-bit resolution, enabling micro-strain detection (e.g., ±0.001% deformation in structural monitoring) without signal degradation.
Integrated Diagnostics: Built-in channel fault detection for open-circuit, short-circuit, and out-of-range signals, reducing system downtime by 30% through proactive alerts.
Flexible Signal Handling: Supports direct connection to strain gauges (full-bridge/half-bridge) and thermocouples, bypassing costly signal conditioners. Each channel independently configurable via GE Proficy software.
Industrial Robustness: Operates in -40°C to 85°C storage temperatures and withstands 15G mechanical shocks, ideal for mobile equipment and harsh environments like mining or offshore platforms.
Application Areas
- Process Industries: Monitors reactor vessel stress and pipeline integrity in oil refineries, leveraging ATEX certification for hazardous zones.
- Manufacturing: Integrates with robotic arms for real-time load feedback during precision assembly, preventing overload failures.
- Energy Infrastructure: Measures turbine blade deformation in power plants using strain gauges, enabling predictive maintenance.
- Automotive Testing: Captures chassis stress data in crash simulations via high-speed sampling (100 samples/sec per channel).
