Description
Product Overview
The GE IC695ALG508CA is an 8-channel isolated analog input module designed for GE’s PACSystems RX3i platform, delivering high-precision signal acquisition in demanding industrial environments. This module supports versatile input types including voltage (±10V, ±5V), current (0–20mA, 4–20mA), and thermocouples (J/K/T/E), with 16-bit resolution for accurate monitoring of critical process variables like pressure, temperature, and flow rates. Engineered with channel-to-channel isolation (1500V AC) and channel-to-backplane isolation (2500V AC), the IC695ALG508CA eliminates ground loops and ensures signal integrity in electrically noisy settings such as power plants or chemical facilities. Its hot-swappable design enables maintenance without system shutdown, while onboard diagnostics provide real-time health alerts via GE’s Proficy software. As a core component in scalable automation architectures, this module enhances predictive maintenance and process optimization across continuous industrial operations.

Key Features and Advantages
Precision Signal Acquisition: Utilizing sigma-delta ADCs with programmable noise filtering (50/60Hz rejection), the IC695ALG508CA achieves ±0.1% baseline accuracy for critical measurements like reactor temperatures or pump vibrations. Each channel incorporates independent fault detection for open-circuit, overrange, and thermocouple cold-junction compensation (CJC), reducing calibration downtime by 40%.
Robust Electrical Protection: Dual isolation barriers (1500V inter-channel, 2500V to backplane) prevent cross-talk and ground loops in multi-sensor installations, essential for substations or chemical plants with high electromagnetic interference.
Operational Flexibility: Direct thermocouple input with automatic CJC eliminates external transmitters. Spring-clamp terminals accept up to 14 AWG wire, simplifying installation in tight spaces. Hot-swap capability ensures zero downtime during module replacement, while per-channel LED status indicators enable rapid troubleshooting.
Future-Proof Integration: Compatible with RX3i VME64 backplanes and programmable via GE Proficy Machine Edition. Embedded webserver support allows remote diagnostics, reducing onsite interventions for distributed facilities like water treatment plants.
Application Areas
The GE IC695ALG508CA excels in industries requiring high-fidelity analog monitoring:
- Power Generation: Monitors turbine bearing temperatures, generator hydrogen purity, and boiler feedwater pH in SIL 2 safety loops, triggering pre-failure alarms.
- Water/Wastewater: Tracks flowmeter totalization (4–20mA) and dissolved oxygen levels across pump stations, optimizing resource usage in municipal treatment systems.
- Oil & Gas: Safeguards compressor vibration and wellhead pressure safety valves in hazardous areas, leveraging ATEX-compliant isolation.
- Pharmaceutical Manufacturing: Ensures FDA-compliant temperature logging for batch reactors via thermocouple inputs with traceable calibration.

Installation and Maintenance
Installation Preparation: Power down the RX3i rack before insertion. Verify backplane firmware supports analog modules (v8.0+). Use shielded twisted-pair cables grounded at one end, and separate high-voltage wiring (>120V) by ≥15cm to prevent interference.
Maintenance Recommendations: Calibrate inputs annually with traceable standards. Monitor “Module Health” in Proficy software for drift alerts. Clean terminals quarterly with isopropyl alcohol to prevent corrosion. Replace after 10 years or if diagnostic LEDs indicate persistent faults.
Product Assurance
The GE IC695ALG508CA includes a 12-month global warranty against manufacturing defects. GE provides lifetime technical support and 10-year spare parts availability. All modules undergo IEC 60068-2 vibration/shock testing and SIL 2 functional safety certification (IEC 61508).
