GE RX3i IC695 Series Technical Notes

The Evolution of IC695 Architecture

The PACSystems RX3i platform was introduced in the mid-2000s as GE Fanuc's answer to the demand for a unified, high-throughput PLC/DCS hybrid. The IC695 designation identifies modules designed for the RX3i universal backplane (IC695CHS012, IC695CHS016), which operates on a dual-bus architecture: a legacy 32-bit serial backplane for backward compatibility with IC694/IC693 modules, and a high-speed PCI-based backplane for native RX3i modules. Early IC695 CPUs (IC695CPU310, IC695CPU320) supported up to 10 MB of user memory. Subsequent generations introduced the IC695CPE302 and IC695CPE305 with expanded Ethernet ports and IEC 61131-3 structured text support. The IC695ALG626 itself belongs to the analog I/O generation that introduced HART (Highway Addressable Remote Transducer) protocol pass-through, enabling field device diagnostics without additional wiring infrastructure — a significant advancement for process industries requiring NAMUR NE107 compliance. Compatibility note: IC695 analog modules are not backward-compatible with IC694 backplanes without a carrier adapter.

Quality Control for the IC695 Range

IC695 analog modules present specific test challenges due to their isolated backplane interface and HART modem circuitry. DriveKNMS applies a multi-stage verification protocol to all IC695ALG626 and related analog modules: (1) Backplane bus continuity test — verifies PCI and serial backplane connector integrity using a dedicated RX3i test chassis; (2) Channel-by-channel analog calibration — each of the 8 input channels is swept across the full 4–20 mA and 0–10 V range using a Fluke 725 calibrator, with deviation logged against GE's published ±0.1% accuracy specification; (3) HART communication verification — a HART master device interrogates each channel to confirm modem response at 1200 baud FSK; (4) Isolation resistance test — channel-to-channel and channel-to-backplane isolation verified at 500 VDC; (5) Thermal burn-in — 48-hour powered soak at 50°C ambient to screen latent component failures. Modules passing all five stages are issued a DriveKNMS test certificate with technician ID and date stamp.
