The IC695ALG508, produced by Emerson Automation and formerly developed by GE Intelligent Platforms (GE IP), is a Resistance Temperature Detector (RTD) input module for the PACSystems RX3i Programmable Automation Controller (PAC) platform. It provides eight (8) isolated, differential RTD input channels designed for precise temperature measurement and reliable performance in industrial applications. Each channel supports a variety of RTD sensor types, including Platinum 385, Platinum 391.6, Nickel 672, Nickel 618, Nickel-Iron 518, and Copper 426, ensuring broad compatibility with standard temperature sensing elements. The module also accommodates direct resistance inputs across selectable ranges of 0–260, 0–525, 0–1050, 0–2100, 0–3150, and 0–4200 ohms, offering versatile configuration for process monitoring and control. The IC695ALG508 may be implemented in automation systems across North America, Europe, Asia, and worldwide, where accurate RTD measurement, wide-range resistance compatibility, and stable analog input performance are critical for high-precision industrial temperature control.
