Description
Product Overview
The GE IC695ALG412CA is a high-performance strain gauge and thermocouple input module designed for industrial automation systems requiring precise measurement of low-level analog signals. As part of GE’s PACSystems RX3i platform, this module integrates seamlessly with PLCs and distributed control systems (DCS) to enable real-time monitoring of critical parameters in applications such as process control, energy production, and manufacturing.
Featuring 12 isolated differential input channels, the IC695ALG412CA supports direct connection to strain gauges, thermocouples (J, K, T, E, R, S, B, N, or C types), and millivolt signals (±150mV or ±50mV) without external signal conditioning1. Its 32-bit IEEE floating-point resolution ensures exceptional accuracy, making it ideal for applications demanding sub-millivolt precision. The module’s Σ-Δ analog-to-digital converter (ADC) technology reduces noise interference and delivers stable readings even in electrically noisy environments.
With 250VAC continuous isolation between channels and a wide operating temperature range (-40°C to +85°C), the IC695ALG412CA meets rigorous industrial standards for reliability and durability. Its modular design simplifies system expansion, while built-in diagnostic tools provide real-time insights into channel status, ensuring proactive maintenance and minimizing downtime.

Key Features and Advantages
Multi-Signal Compatibility: The IC695ALG412CA eliminates the need for external signal conditioners by directly interfacing with strain gauges and thermocouples. This reduces hardware complexity and lowers installation costs while maintaining ±0.25% full-scale accuracy across its operational range.
Enhanced Noise Immunity: Its Σ-Δ ADC architecture and 10 dB noise suppression filter out electromagnetic interference, ensuring reliable measurements in high-noise environments like power plants and manufacturing facilities.
Advanced Diagnostics: Built-in LED indicators and remote monitoring tools provide real-time feedback on channel health, including open-circuit detection, short-circuit protection, and over/under-range alerts. This proactive approach minimizes unplanned outages and extends component lifespan.
Flexible Configuration: Engineers can configure input types, sampling rates, and data formats (floating-point or integer) via GE’s Proficy Machine Edition software, streamlining integration with existing control systems.
Rugged Design: Withstanding 15G shock and 1G vibration, the module is engineered for harsh industrial environments. Its wide temperature range (-40°C to +85°C) and IP20-rated enclosure ensure consistent performance in extreme conditions.
