GE Fanuc IC697ALG320D – Series 90-70 Multi‑Channel Analog Input Module for Reliable Process Signals
The GE Fanuc IC697ALG320D is an analog input module for the Series 90‑70 platform, designed to bring multiple field signals—typically voltage and current—into your PLC with stable, low‑noise performance. From my experience, plants choose this module when they need steady analog acquisition on established 90‑70 racks without retraining crews or rewriting entire programs. You might notice that its behavior is very predictable in most cases, which makes commissioning and scaling a lot less stressful.

Key Features
- Series 90‑70 rack compatible – Installs directly on an IC697 backplane; no special adapters required.
- Multi‑channel analog input – Suitable for bringing in multiple process variables from instruments and transducers in one slot.
- Typical ranges supported – Common industrial ranges such as ±10 V and 0/4–20 mA are typically supported, easing migration from existing loops.
- Stable conversion – Designed for consistent readings and low drift; helps maintain tight control in batching, utilities, and OEM skids.
- Diagnostics and status – Front indicators and built‑in self checks make channel status and fault finding more straightforward.
- Configured with standard GE tools – Parameterized via Logicmaster 90‑70 or Proficy Machine Edition (Logic Developer – PLC) in most cases.
- Field wiring flexibility – Works well with shielded twisted pairs; supports typical single‑ended or differential wiring practices depending on range and noise environment.

If you’re replacing an existing Series 90‑70 AI card, IC697ALG320D fits well where multiple voltage/current channels are needed without changing the rack or software approach. One thing I appreciate is how these modules behave predictably across mixed loop types—handy when plants standardize on 4–20 mA yet keep a few ±10 V instruments around.
Installation & Maintenance
- Cabinet & environment: Mount in an enclosed control cabinet with adequate ventilation. Keep ambient 0–60 °C, humidity below 95% RH non‑condensing. Allow space for airflow around the rack.
- Wiring practices: Use shielded twisted pairs for analog signals; separate from high‑voltage and motor cables. Ground shields at one end only to avoid ground loops. For 4–20 mA loops, an isolated 24 VDC supply typically yields the lowest noise.
- Grounding: Bond panel ground and signal reference properly. You might notice noise decreases significantly when the shield and commons are managed consistently across the cabinet.
- Commissioning: Configure channel ranges and scaling in Logicmaster 90‑70 or Proficy ME. Validate with a calibrator (e.g., 4 mA, 12 mA, 20 mA points) and record offsets for maintenance history.
- Safety: De‑energize the rack before inserting or removing modules. Observe ESD precautions when handling the board.
- Routine checks: Inspect terminal tightness, cable strain relief, and shield terminations every shutdown. Clean dust with dry air; verify analog scaling annually or after field device replacement.
Quality & Certifications
- Typically conforms to CE and UL/cUL for industrial control equipment.
- Built for Series 90‑70 quality standards; revision “D” indicates a mature hardware iteration.
- RoHS status can vary by production date; many legacy 90‑70 modules pre‑date strict RoHS regimes.
- Standard manufacturer warranty practices apply; our sales warranty is 365 days as stated above.
Customer feedback from a food & beverage line upgrade: “Swapping in IC697ALG320D let us keep our existing 4–20 mA loops. Noise dropped after we moved shields to a single‑point ground and separated the VFD cable tray—the readings have been rock solid since.”
