Product Introduction
When upgrading or maintaining legacy control systems, the GE IC697ALG230 base converter module ensures reliable analog input conversion. Part of the Series 90-70 PLC family, this module was originally manufactured by GE Fanuc and is now supported by Emerson Automation. The IC697ALG230 offers eight differential inputs that can be individually configured for voltage or current signals, providing flexibility in diverse industrial applications.

Industry Applications
The GE IC697ALG230 is ideal for process control environments requiring accurate monitoring of analog signals. Common applications include temperature sensing with 4-20 mA transmitters, pressure monitoring with voltage outputs, and level measurement. Its differential wiring configuration provides excellent immunity to electromagnetic interference, ensuring stable readings in electrically noisy plant floors. For cost-conscious operations, the module's high accuracy reduces calibration frequency, lowering total cost of ownership.
Compatibility & Integration
The IC697ALG230 integrates seamlessly with GE Series 90-70 PLC systems. It supports up to seven expander modules—specifically the IC697ALG440 Voltage Expander and IC697ALG441 Current Expander—expanding the system to handle up to 120 inputs. This modularity allows scalability without replacing the base module. The module also offers CPU alarm interrupts and fault reporting per channel, simplifying diagnostics.
Selection Guide & Purchasing Advice
Before purchasing a GE IC697ALG230, verify that your PLC backplane supports the Series 90-70 format. The module includes a removable 40-terminal connector block for user wiring. As this product is discontinued, sourcing from reliable suppliers is crucial. UBEST Automation (available at ubest101.myshopify.com) stocks authentic legacy parts with verified specifications. Ensure you have the necessary expander modules if your application requires more than 8 inputs.
