GE IC697CPX935-CB Single-Slot CPU Module

Description

Engineers specify GE IC697CPX935-CB for PLC racks in cement kilns, pharmaceutical batching suites, or offshore platforms where scan consistency across thousands of I/O points directly impacts throughput and safety compliance. You’ll see it managing valve matrices, level cascades, and emergency shutdowns in facilities that can’t tolerate overruns during recipe changes or fault resets. In wastewater lift stations or steel slab casters, GE IC697CPX935-CB coordinates discrete interlocks with analog loops over extended remote drops, linking seamlessly to DCS layers without added gateways. Because it is used in industrial automation where field crews prioritize drop-in reliability over platform shifts, plants keep it stocked for quick swaps during tight outage windows.

This CPU thrives in upgrades where operators refresh processing power inside existing Series 90-70 cabinets, absorbing denser logic for historians, motion profiling, or redundancy handoffs while preserving legacy I/O maps and serial links. GE IC697CPX935-CB handles the load of 12K mixed I/O with floating-point math at 0.4 microsecond Boolean speeds, making it a go-to for sites scaling from basic sequencing to predictive maintenance interfaces. Maintenance teams value its field-proven uptime in humid process areas or dusty mills, where deterministic sweeps prevent the ripple effects of a single delayed contact.

The payoff is straightforward: extended rack life without the engineering lift of a full control refresh.

The GE IC697CPX935-CB is a top-tier single-slot CPU from GE Fanuc’s Series 90-70 lineup, built around a 96 MHz 80486DX4 processor with integrated floating-point hardware for real-time control in complex PLC systems. It packs 1 MB battery-backed RAM for active logic alongside 256 KB flash for user data and firmware, letting programmers handle expansive ladder and structured routines without memory swaps. Within a rack setup, GE IC697CPX935-CB slots into the CPU position, talking backplane to I/O scanners and comms cards while exposing three serial ports for direct Modbus, SNP, or HMI ties.

Ranked among the fastest 90-70 options, this model suits growing applications—from high-density discrete networks to analog-heavy processes—while supporting IC660 remote buses and LAN interfaces for plant-wide reach. Integrators lean on GE IC697CPX935-CB for its in-system flash updates, run-mode stores, and multi-threaded LD capabilities that streamline expansions without halting production. Paired with Proficy or MS-DOS tools, it keeps projects portable across 90-70 fleets, offering a bridge for sites eyeing Ethernet without abandoning proven wiring.

GE IC697CPX935-CB stands out with processing muscle that chews through Boolean webs and PID farms at consistent 0.4 µs clips, even under max I/O polls or data bursts—vital for sync’d drives or safety chains in motion systems. The 1 MB RAM swallows large programs with room for trends and recipes, while flash guards against outages, snapping back online fast to hold batch integrity or sequencer states.

A compact single-slot design eases retrofits into crowded racks, sipping 3.1 A from the 5 V rail with a front panel blending LEDs, keyswitch, and ports for hands-on diagnostics. One RS-232 and dual RS-485/RS-422 ports—one isolated—flex for programmer hookups or RTU roles up to 57.6K baud, no extra hardware needed. Bulk Memory Access and real-time clock (3.5 s/day accuracy) add scheduler precision for audits or timed events.

It meshes perfectly with IC697 discrete/analog modules, IC660/IC661 remotes, and coprocessors, scaling to full plant coverage via Genius or serial links. Rated to 60°C with lithium battery holdup (6 months powered, 5 years shelf), GE IC697CPX935-CB weathers cabinet heat and EMI, logging years in continuous duty where peers falter.

Power down the rack before sliding GE IC697CPX935-CB into its slot—check backplane seating, power budget for the 3.1 A pull, and firmware parity with I/O peers to dodge boot loops. Route serial cables away from power trays, lock in 2U front clearance for switch flips and LED scans, and vent cabinets to hold under 50°C ambient, especially with battery heat in long runs. Programmer via Port 1 first: zero the config, map I/O tables, set baud/parity, then cycle to RUN with password guards active per site policy.

Maintenance means battery swaps every 4 years (test holdup annually), quarterly rack vacuums in gritty spots, and diagnostic sweeps for port drops or scan spikes—flash updates stay internal via Ethernet, but clone logic offline first. Stock GE IC697CPX935-CB spares by revision to cut swap-to-scan times, and trend backplane faults to preempt rack refreshes.
