Order now IC695ALG600 GE Fanuc Analog Module
The IC695ALG600 stands out as a state-of-the-art, 8-Channel Universal Analog Input Module manufactured by GE Fanuc for the high-performance PACSystems RX3i controller series. Engineered to offer unparalleled flexibility, this module allows system designers to consolidate their hardware by accepting multiple types of analog signals on a single card. Each of the 8 fully isolated channels can be independently configured via software to accept voltage (±10V, 0-10V), current (4-20mA, 0-20mA), RTDs (Resistance Temperature Detectors), thermocouples, or pure resistance signals. Featuring a 16-bit analog-to-digital converter, the IC695ALG600 delivers exceptional measurement accuracy and resolution, making it an indispensable asset for critical process control applications, such as chemical dosing, advanced metallurgy, and precision HVAC monitoring.

Advanced Shielding and Wiring Tips
Due to the high sensitivity and 16-bit resolution of the IC695ALG600, mitigating electromagnetic interference (EMI) is non-negotiable. Always utilize high-quality, twisted-pair shielded cables for all analog runs. When connecting thermocouples, the shield wire must be grounded at one end only—preferably at the PLC chassis ground—to eliminate destructive ground loops. When configuring a channel for a 4-20mA current loop, verify whether the field transmitter is active (sourcing power) or passive (requiring loop power), as the wiring scheme to the module’s high-density terminal block will change accordingly to prevent overcurrent damage.
Calibration and Ongoing Maintenance
The IC695ALG600 boasts advanced onboard diagnostics, including open-wire detection, over-range alarms, and under-range alerts, which can be mapped directly into the CPU’s logic for real-time SCADA monitoring. Maintenance is streamlined because the module performs continuous self-calibration during operation, negating the need for periodic manual zero-and-span adjustments with potentiometers. However, for heavily regulated industries (like pharmaceuticals), it is advisable to routinely verify the module’s readouts against a certified process calibrator. Keep the terminal blocks free of dust and moisture to prevent microscopic leakage currents that could skew temperature readings.
Integrated System Architecture
In extensive plant layouts, this precision analog module is perfectly suited to operate in a remote field enclosure, gathering critical temperature and flow data and transmitting it back to the main CPU via the IC695NIU001 Ethernet communications node.
Frequently Asked Questions (FAQs)
Q: Does the IC695ALG600 require external cold junction compensation hardware for thermocouples?
A: No, the module features built-in Cold Junction Compensation (CJC) terminals, ensuring highly accurate temperature readings without the need for additional external compensating hardware.
Q: Can I configure channel 1 for a PT100 RTD and channel 2 for a 0-10V sensor simultaneously?
A: Absolutely. Each of the 8 channels is completely independent and can be configured through the Proficy Machine Edition software to handle entirely different signal types at the same time.
