Order now IC695ALG106 GE Fanuc PACSystems RX3i Isolated Analog Input
Order now IC695ALG106 to achieve absolute signal purity and pinpoint precision in your most demanding continuous process control applications. The GE Fanuc IC695ALG106 is an incredibly versatile, high-resolution 6-Channel Analog Input Module designed exclusively for the PACSystems RX3i PCI Express backplane. What elevates this module above standard analog cards is its complete channel-to-channel galvanic isolation. This means each of the 6 inputs possesses its own independent A/D converter and isolation barrier, completely eliminating the risk of ground loops or cross-channel interference. Furthermore, the IC695ALG106 is universally configurable; every single channel can be individually programmed via software to accept voltage, current, resistance, RTDs, or direct Thermocouple inputs. This unmatched flexibility allows engineers to consolidate diverse sensor types onto a single module, saving precious backplane space and dramatically reducing hardware inventory costs. By integrating this genuine OEM module, your facility guarantees 16-bit analog accuracy, ensuring flawless PID loop tuning and exact process variable tracking.

Expert Configuration and Cold Junction Compensation Tips
Because the IC695ALG106 can read microvolt-level Thermocouple signals, proper installation of Cold Junction Compensation (CJC) is paramount. When wiring thermocouples to this module, you cannot use standard copper wire from the sensor to the terminal block; you must use the appropriate extension wire for your specific thermocouple type. Furthermore, to accurately calculate absolute temperature, the module must know the temperature at the terminal block itself. You must install a dedicated GE Fanuc CJC sensor (typically a specialized thermistor) across the designated CJC terminals on the detachable block. Failure to properly shield the terminal block from ambient drafts or neglecting to install the CJC sensor will result in temperature readings drifting wildly as the electrical cabinet heats up or cools down during the day.
Frequently Asked Questions (FAQs)
Does this module provide 24V loop power for current transmitters? No. While the IC695ALG106 is designed to read 4-20mA current loops with extreme precision, it does not source the excitation voltage. You must wire a dedicated, regulated 24 VDC power supply in series with your field transmitters to power the loop.
How is open-wire detection handled on the IC695ALG106? The module features advanced internal diagnostics that continuously monitor the integrity of the sensor circuit. If a wire breaks or a thermocouple burns out, the module instantly flags an open-wire fault to the CPU fault table and can drive the logic value to a pre-configured safe state (e.g., maximum scale or minimum scale).
Is calibration required after installation? The module is highly calibrated at the factory for all input ranges. However, if your specific ISO 9001 quality system requires field calibration, the Proficy Machine Edition software provides a dedicated hardware configuration tab to enter specific zero and span offsets for each individual channel.
