GE IC694ALG392 PACSystems RX3i Analog Input Module
Product Overview
The GE IC694ALG392 is a high-performance analog input module designed for GE’s PACSystems RX3i automation platform, a cornerstone of industrial control systems in manufacturing, energy, and infrastructure sectors. As a 16-channel module, the IC694ALG392 converts analog signals from field sensors (such as pressure transducers, thermocouples, and RTDs) into digital data for processing by the RX3i controller, enabling precise monitoring of critical process variables.
Engineered for versatility, the IC694ALG392 supports multiple input types, including 4-20mA, 0-10V DC, and thermocouples (J, K, T, E, R, S, B), making it suitable for diverse applications. Its 24-bit resolution and 0.05% accuracy ensure reliable measurements even in noisy industrial environments, while channel-to-channel isolation prevents signal interference. The module operates across -40°C to +70°C, with a rugged metal enclosure that withstands vibration, humidity, and corrosive atmospheres—ideal for offshore platforms, power plants, and chemical facilities.
Within the RX3i ecosystem, the IC694ALG392 integrates seamlessly with controllers like IC694CPU313 and terminal boards such as IC694TBM302, forming a cohesive analog monitoring system. LED indicators provide real-time status for power, communication, and channel faults, simplifying diagnostics. Compliance with UL 508 and IEC 61010 standards underscores its reliability in regulated industrial settings.

Main Features and Advantages
High-Precision Measurement: The IC694ALG392 delivers 24-bit resolution and 0.05% accuracy, ensuring precise conversion of analog signals from sensors. This level of precision is critical for applications like pharmaceutical manufacturing, where temperature or pressure variations of even 0.1% can affect product quality.
Flexible Input Configuration: Each of the 16 channels can be independently configured for 4-20mA, 0-10V DC, or thermocouples, eliminating the need for multiple modules. This flexibility reduces inventory costs and simplifies system design, especially in mixed-signal environments like food processing plants.
Rugged Industrial Design: With a -40°C to +70°C operating range and 250V AC isolation, the IC694ALG392 thrives in harsh conditions. Its metal enclosure and conformal coating resist dust, moisture, and electromagnetic interference (EMI), making it suitable for steel mills, mines, and offshore platforms.
Seamless RX3i Integration: The module works natively with RX3i controllers, using the backplane for high-speed data transfer. It pairs with IC694TBM302 terminal boards for easy wiring and IC694BEM331 communication modules for Ethernet connectivity, enabling integration with SCADA systems and cloud platforms.
Advanced Diagnostics: LED indicators for power, communication, and channel faults provide instant visual feedback. Internal self-tests continuously verify component health, while alerts for open thermocouple wires or overrange signals enable proactive maintenance—reducing downtime in 24/7 operations.
Application Fields
The GE IC694ALG392 is integral to industries requiring accurate analog signal monitoring:
- Power Generation: Monitors steam pressure, turbine vibration, and generator winding temperatures in thermal and nuclear plants. Its thermocouple support ensures reliable measurements in high-temperature environments like boiler chambers.
- Oil and Gas: Tracks wellhead pressure, pipeline flow rates, and compressor discharge temperatures in offshore platforms. The module’s rugged design withstands salt spray and vibration, ensuring continuous operation in remote, unmanned facilities.
- Chemical Processing: Measures reactor temperature, pH levels, and chemical concentration in batch processing. Its high accuracy and isolation prevent cross-contamination of signals, critical for maintaining process purity.
- Automotive Manufacturing: Monitors hydraulic pressure in stamping presses and oven temperatures in paint shops. The flexible input configuration allows integration with legacy sensors and new IoT-enabled devices.
