Product Role & System Fit
The IC697ALG440F is an analog input expander module. In the Series 90‑70 analog subsystem architecture, a base converter module (such as the IC697ALG230) sits in the rack, and the expanders like the IC697ALG440F plug in adjacent to it. The expander provides 16 analog input channels (current or voltage) which the base converter converts and presents to the PLC CPU as %AI words.
What this means in system fit: if you have a GE Series 90‑70 PLC system, and you require more analog inputs than your base converter alone supports, you can add one or more IC697ALG440F modules to the rack to increase channel count. Up to 7 expanders can be used with a single base converter, giving flexibility up to ~120 analog inputs in the subsystem.
From an integration standpoint, the module doesn’t require DIP switch or jumper configuration—all channel scaling is done via software. This simplifies integration and reduces field mistakes.
For system architects, this provides capacity planning flexibility: start with a smaller analog subsystem today, and add expanders like the IC697ALG440F later as your measurement needs grow—without reworking the logic or backplane wiring significantly. Because the module uses the same backplane and wiring conventions as other Series 90‑70 I/O, maintenance crews find familiarity remains.
In high‑availability plants, the module can be part of redundant racks and fault‑tolerant designs (depending on the rest of the architecture). Its diagnostics help identify failing channels or modules before they impact operations, improving system uptime.
