Description
Product Overview
The GE IC695ALG808 is an isolated analog output module designed for Emerson’s PACSystem RX3i platform (formerly under GE Intelligent Platforms). Featuring eight independently isolated channels, it generates precise voltage (±10V, 0-10V) or current (0-20mA, 4-20mA) signals to control actuators like VFDs, valves, and dampers in industrial automation systems. With configurable resolution (15-bit for most ranges, 10-bit for 0-10VDC) and rapid 8 ms/channel update rate , the GE IC695ALG808 ensures real-time responsiveness for dynamic processes such as flow regulation and pressure control. Its rugged design operates reliably in temperatures from -20°C to 60°C , making it ideal for harsh environments in chemical plants, manufacturing lines, and energy facilities. The module integrates seamlessly with RX3i universal backplanes and supports software-configurable alarms (e.g., high/low limits, rate-of-change alerts), enhancing system stability while reducing calibration needs .

Key Features and Advantages
Precision & Robust Isolation:
15-bit resolution (10-bit for 0-10VDC) with channel-to-channel isolation (250 VAC continuous) eliminates signal cross-talk, ensuring accuracy in electrically noisy environments like motor control centers .
Dynamic Control & Diagnostics:
- Software-configurable output ranges (voltage/current per channel) replace hardware jumpers, enabling rapid field reconfiguration .
- Integrated alarms (overrange/underrange, rate-of-change) and auto-calibration detect drift, supporting predictive maintenance .
High Compatibility & Protection:
- Compatible with RX3i backplanes and multiple terminal types (e.g., spring-clamp IC694TBS032, box-type IC694TBB032) .
- Overvoltage protection (-30V/60s, +30V/1h) and low drift (20 ppm/°C voltage, 35 ppm/°C current) extend lifespan in extreme conditions .
