Product Role & System Fit
The GE IC697MEM735 isn’t a CPU or I/O processor; its function is singular yet indispensable — expand and preserve memory inside GE Fanuc Series 90-70 controllers. In real-world automation architectures, PLC logic and operational data reside in memory that can be volatile without battery support. The GE IC697MEM735 provides that support as a 32-bit CMOS memory board.
Unlike external storage modules that occupy additional rack space, this memory expander installs directly on compatible CPU modules as a daughterboard. This design conserves slots and simplifies rack layouts, particularly in systems constrained by space or requiring tidy hardware configurations.
Integration into a PLC system must align with both hardware and software. The GE IC697MEM735 is compatible with several Series 90-70 CPU families — including model variants 780, 781, 782, 788, and 789 — allowing engineers to unify memory expansion strategy across different controller types.
Once installed, this module interfaces with the CPU’s memory bus, effectively expanding the available RAM used for logic execution, data tables, and system overhead. It works in conjunction with the CPU’s onboard battery circuitry to sustain memory during power interruptions. Crucially, it also supports long memory retention — typically around six months without applied power — and benefits from optional lithium battery replacement to extend service life.
By offloading program and data storage needs to a dedicated memory expander, the GE IC697MEM735 allows CPUs to focus on logic execution without internal storage constraints. In larger automation schemes where logic size and data load can grow over time, this architectural choice provides headroom and flexibility that matter in both new builds and modernization projects.
