GE Fanuc IC697ALG234 – Series 90-70 Analog Input Module for Industrial Voltage/Current Signals

The IC697ALG234 is a Series 90-70 analog input module designed for process signals in demanding control panels. From my experience, it’s a solid fit when you need stable measurement of plant-wide voltage or 4–20 mA current loops without reworking your existing GE Fanuc IC697 rack. You might notice that it plays especially well in legacy upgrades where extra analog points are needed—water/wastewater, metals, and batch systems are typical examples.

Key Features

• Analog input for voltage and current signals – typically supports common ranges such as 0–10 V, ±10 V, and 0/4–20 mA for process instrumentation.
• Seamless Series 90-70 integration – plugs directly into IC697 racks and communicates via the native backplane bus, no external interface needed.
• High-density channel design – suited for expanding measurement points in existing cabinets without major wiring changes.
• Stable measurements in industrial environments – engineered for electrical noise found around drives, pumps, and heavy machinery when properly grounded and shielded.
• Per-channel configuration in many cases – ranges and scaling can be set to match field transmitters, which reduces marshalling headaches.
• Lifecycle-friendly – ideal for maintaining or expanding legacy GE Fanuc systems while keeping I/O cards consistent across lines.

Technical Specifications

Where it fits best

Plants running legacy GE Fanuc 90-70 racks that need more analog monitoring points—think converting manual gauges to PLC monitoring, tying in extra pressure/level transmitters, or bringing VFD analog feedback into the control layer. One thing I appreciate is how painless it usually is to scale up without disturbing the CPU or comms cards.

A maintenance lead from a food plant told us they used the IC697ALG234 to pull in an additional 12 current loops from CIP skids. “Dropped it in the spare slot, mapped the addresses, and we were trending within the shift.” That’s fairly typical when the wiring is prepped and grounding is handled cleanly.

Installation & Maintenance

• Cabinet environment – Maintain clean, dry, and ventilated enclosures. Keep ambient typically within 0–60°C; avoid heat sources directly beneath the module.
• Grounding & shielding – Use shielded twisted pair for analog runs; land shields at one end (usually the panel end) to reduce ground loops.
• Wiring – Separate analog from power and motor cables. Keep analog loops away from VFD outputs and contactor wiring; route in dedicated ducting where possible.
• Power budget – Confirm backplane 5 VDC capacity with the PSU datasheet when adding multiple I/O cards.
• Configuration – Set input ranges and scaling per channel in the programming software; verify with a calibrated source before going live.
• Maintenance – Periodically check terminal tightness and inspect for corrosion or loose shields. Calibration is typically not user-required, but it’s wise to spot-check with a portable calibrator annually in regulated environments.
• Firmware/compatibility – On legacy systems, match module firmware and CPU revisions when possible; it appears that most IC697 analog I/O is tolerant of mixed revisions, but it’s worth a quick check.

Quality & Certifications

• Certifications: CE and UL/cUL are typical for Series 90-70 modules; RoHS compliance depends on specific build/revision due to the platform’s age.
• Warranty: 365-day warranty from shipment
• Testing: Modules are function-tested prior to dispatch; packaging is anti-static with shock protection.
