Description
Product Overview
The GE IC695ALG808CA is an isolated analog output module designed for Emerson’s PACSystem RX3i platform (formerly under GE Intelligent Platforms). Featuring eight independently isolated channels, it delivers high-precision voltage (±10V, 0-10V) or current (0-20mA, 4-20mA) signals to control actuators like VFDs, valves, and dampers in industrial automation systems. With a configurable resolution (15-bit for most ranges, 10-bit for 0-10VDC) and rapid 8 ms/channel update rate, the GE IC695ALG808CA ensures real-time responsiveness for dynamic processes such as flow regulation and pressure control. Its rugged design operates reliably in temperatures from 0°C to 60°C, making it ideal for harsh environments in chemical plants, manufacturing lines, and energy facilities. The module supports software-configurable alarms (e.g., overrange, rate-of-change) and integrates seamlessly with RX3i backplanes, enhancing system stability while minimizing calibration efforts.
