Product Overview
The GE IC695ALG112 is a high-precision isolated analog input module from Emerson’s PACSystems RX3i platform, originally developed by GE Intelligent Platforms. Designed for critical process monitoring, this module features eight (8) individually isolated single-ended input channels, configurable to accept a wide range of voltage (±10V, 0–10V, ±5V) and current signals (0–20mA, 4–20mA). Utilizing a 16-bit analog-to-digital converter (ADC), the GE IC695ALG112 delivers exceptional accuracy (±0.1% at 25°C) and supports both IEEE 32-bit floating-point and 16-bit integer data formats. Integrated software-configurable filters (8Hz–1000Hz) eliminate signal noise in electrically harsh environments like substations or manufacturing floors. As part of the RX3i series, this module enables seamless integration with PCI-based backplanes (e.g., IC695ACC400CA), providing real-time data for SCADA, DCS, and HMI systems. Its compact design and hot-swap capability make the GE IC695ALG112 ideal for modernizing legacy systems while minimizing cabinet space .

Key Features and Advantages
Advanced Signal Integrity: Each channel provides independent 250V AC isolation and software-selectable notch filtering (8Hz–1000Hz), eliminating ground loops and EMI interference in high-noise environments like power substations. Combined with HART protocol support (via firmware), the module enables predictive maintenance for sensors without additional hardware .
Comprehensive Diagnostics: Real-time detection of wire breaks, short circuits, and signal over/under-range conditions via per-channel LEDs. This reduces mean-time-to-repair (MTTR) by 40% in critical applications such as chemical dosing systems .
Flexible Integration: Hot-swappable design allows replacement during operation without process interruption. Native compatibility with RX3i CPUs (e.g., IC695CPE310) and GE’s Proficy Machine Edition software simplifies configuration and scaling for brownfield upgrades .
Application Areas
- Energy Infrastructure: Monitors grid voltage and turbine vibration sensors in substations, leveraging surge immunity (4kV ANSI C37.90) for high-voltage environments .
- Water/Wastewater Treatment: Interfaces with pH/flow transmitters in remote SCADA stations; corrosion-resistant terminals ensure reliability in humid conditions .
- Discrete Manufacturing: Acquires temperature and pressure data from injection molding machines, enabling closed-loop control via RX3i PACs .
- Building Automation: Integrates with HVAC damper controls and fire safety systems, utilizing low standby power (<1W) for sustainable operations .
