Description
Are you struggling with signal noise or resolution loss when integrating high-precision sensors into your legacy Series 90-70 system? The GE Fanuc IC697ALG230J is a high-performance analog input module designed for industrial applications requiring 12-bit conversion of voltage or current signals. This module supports eight differential inputs, providing superior noise rejection and signal integrity compared to standard single-ended modules used in less demanding environments.

Technical Specifications and Field Parameters
In field deployments of IC697 hardware, we have found that the “J” revision offers significantly better component longevity and firmware stability than the earlier “A” through “F” versions.

Signal Processing and Calibration
Unlike modern “plug-and-play” modules, the IC697ALG230J relies on precise software configuration through Proficy Machine Edition or Logicmaster 90.
-
Differential Architecture: By measuring the difference between two signal lines rather than signal-to-ground, this module effectively cancels out common-mode noise often found in long cable runs.
-
On-Board Calibration: The module features automated software-based calibration. Honestly, many technicians make the mistake of trying to find physical trim pots—there are none. Calibration constants are stored in EEPROM and updated via the CPU.
Global Procurement and Customs Compliance Notes
Shipping legacy industrial controls internationally requires precise paperwork to navigate “End-of-Life” (EOL) hardware regulations.
Trade Regulations & Compliance
-
US ECCN: EAR99 (Generally unrestricted for commercial use).
-
HS Code: 85389091 (Parts for programmable controllers).
-
Customs Strategy: For international shipments to Southeast Asia or South America, we provide detailed “Commercial Invoice for Customs” documents that clearly state the item is a PLC component to ensure correct tariff application and prevent holds.
Logistics Optimization
We default to FCA (Free Carrier) or DAP (Delivered at Place) terms. Given the VMEbus connector’s sensitivity on the rear of the module, we use custom-molded ESD foam for all international air shipments. The unit weighs approximately 1.1 kg, making air freight the most efficient transport method for minimizing “Mean Time To Repair” (MTTR) during plant outages.
Engineering Notes for Field Deployments
Important Installation Note: The IC697ALG230J is a “High Width” module and occupies a single slot in the IC697 rack, but it requires the use of a 37-pin D-type connector for field wiring. Do not attempt to force standard terminal blocks onto this interface.
Well, technically the module can handle 4 to 20 mA signals, but you must install a precision 250 Ω resistor across the input terminals for each current loop. Without this resistor, the module will only “see” voltage, and your readings will be pegged at the maximum value. To be frank, if you are seeing erratic data, the first thing you should check is the shield grounding—ensure the cable shields are grounded at the module end only to prevent ground loops.
In our experience, the internal 5 V DC backplane draw is quite high (1.1 A). If you are adding this module to a rack that is already near its power supply limit (e.g., an IC697PWR711), you might experience intermittent “Loss of Module” faults. Always perform a power budget calculation before adding analog modules to a Series 90-70 rack.
Frequently Asked Questions
Can the IC697ALG230J replace an IC697ALG230 (without the J)?
Yes. The “J” represents a hardware revision that is fully backwards compatible with all previous versions. It will fit into the same slot and use the same software configuration.
How do I configure the input range for different sensors?
Range selection (e.g., 4-20 mA vs 0-10 V) is performed entirely in the PLC configuration software. There are no hardware jumpers on the board for range selection. After changing settings in the software, you must perform a “Hardware Configuration Download” to the CPU for the changes to take effect on the module.
