Product Role & System Fit
The GE IC697ALG6440 serves as an analog current expander module within GE Fanuc’s Series 90-70 programmable logic controller (PLC) environment. Legacy automation systems like the Series 90-70 rely on modular I/O expansion cards to scale analog signal acquisition as plant requirements grow. The IC697ALG6440, typically a 16-channel analog current expander, is engineered to increase the number of analog inputs available to a PLC beyond what a basic analog base converter can support.
In a rack-based automation system, the more you expand process monitoring — for example, temperature and pressure sensing across distributed field sensors — the more I/O capacity you need. The GE IC697ALG6440 module connects to an existing analog base converter in the rack, presenting its expanded set of input channels through the system backplane. This enables the Series 90-70 controller to treat additional analog data in the same way it would base analog inputs, despite the physical signals entering additional physical module points.
Field engineers commonly deployed expander modules such as this when the size of the analog field network increased over time; for instance, in chemical dosing applications where hundreds of sensors feed loops back into a central control processor. By adding an expander like the GE IC697ALG6440, automation designers preserved existing architecture while letting the controller process more analog signals without adding parallel controller hardware.
The modular architecture of the Series 90-70 platform means expander modules must interface closely with base converters and main PLC CPU units. In practice, this is accomplished by mounting the expander in the same backplane and configuring the overall system so that the CPU recognizes the additional channels under a contiguous analog addressing scheme. The IC697ALG6440 would thus function in harmony with other series modules — including base converters, digital I/O, and specialty cards — to deliver extended analog data acquisition without altering core system logic.
