Product Introduction & Positioning

The IC695ALG608-AB is an advanced, non-isolated, Analog Voltage/Current Input Module, defining its role within the GE Fanuc (now Emerson) PACSystems RX3i platform. As an integral I/O module, it directly plugs into an RX3i universal backplane, establishing high-speed communication with the system’s CPU over the backplane bus.The module acts as the sophisticated interface between the physical analog world of sensors and the high-performance digital architecture of the RX3i controller. It is positioned as a high-density, high-accuracy analog solution, balancing performance with channel count. The value of the IC695ALG608-AB to engineers and integrators lies in its complete software configurability—there are no physical jumpers to set. Every channel’s range ($\pm 10\text{V}$, $4\text{-}20 \text{ mA}$, etc.), filtering ($8 \text{ Hz}$ to $500 \text{ Hz}$), and alarm thresholds (High/Low) are set directly within the Proficy Machine Edition programming software. This dramatically simplifies commissioning and enables rapid, remote configuration changes. Furthermore, the 24-bit resolution ensures that minute signal variations from transmitters are accurately digitized, and its built-in diagnostics, like open-circuit detection on voltage and $4\text{-}20 \text{ mA}$ inputs, make the IC695ALG608-AB highly trustworthy for use in control systems where signal integrity is paramount.
