In refineries where a single pump trip cascades through distillation towers or wastewater plants juggling sludge thickeners across basins, the GE IC695CRU320-EN ensures control never blinks by mirroring logic across redundant pairs. Imagine a steel continuous caster where roll speeds must sync flawlessly—if one CPU stumbles on a sensor fault, the backup seizes in under 4 milliseconds, dodging slab defects worth thousands per ton. Or think of pharmaceutical autoclaves holding sterilize cycles amid power flickers; lost steps mean revalidation and FDA headaches. This CPU powers industrial automation at its toughest, anchoring PACSystems RX3i main racks with hot-standby redundancy over fiber or EGD, supporting up to 512 blocks of ladder logic for real-time discrete and process loops. In transit systems, it fuses rail signals; in mining conveyors, it times overload sheds. Operators program via Proficy over serial ports, loading 64MB RAM/Flash while diagnostics stream to HMIs. Why it owns control systems? Celeron-M at 1GHz crunches 0.047ms per 1000 Booleans, with PCI/serial backplanes migrating 90-30 I/O seamlessly. From gas compression stations to bottling fillers, the GE IC695CRU320-EN turns single points of failure into ironclad pairs, keeping output steady when chaos strikes.
Redundancy Engine
The GE IC695CRU320-EN delivers as a dual-slot Redundancy CPU for Emerson PACSystems RX3i, packing 1GHz Celeron-M processing with 64MB battery-backed RAM and 64MB flash for mission-critical duplex setups. It mates primary/standby units over IC695RMX modules, syncing memory/state in max 1 scan (3.133ms min switchover), programmed through Proficy Machine Edition supporting ladder/FBD/ST up to 128KB blocks. Slots into PCI main racks, extending to remote via serial backplane for 90-30 legacies.
Integrators lean on its RS-232/RS-485 ports for SNP/Modbus RTU programmer ties or RTU polls, offloading comms from scans. Eight front LEDs (CPU OK, RUN, Outputs Enabled, I/O Force, Battery, Sys Flt, COM1/2) flag states instantly, with %S points logging overruns or sync fails. Firmware enables floating-point and high-speed backplanes, scaling to 8K discrete/1K analog I/O. For upgrades demanding zero downtime, the GE IC695CRU320-EN rebuilds trust in redundancy.dosupply+2
Core Strengths
Operators in dual-CPU water systems hail the GE IC695CRU320-EN for bumpless transfers—standby shadows outputs actively, flipping on heartbeat loss without ladder tweaks. LEDs pinpoint battery low or force overrides at a glance, while serial ports daisy legacy HMIs sans Ethernet. Processing hits 3.66ms scans for 1K I/O + 125 analog, parity-protected memory shrugs EMI.
Rugged two-slot chassis draws 1.0A at 3.3V/1.2A at 5V, passively cooled through 60°C with PCI 2.2 compliance for module floods. Self-tests boot reliably, supporting up to 2MB Ethernet data or RMX links for ultra-low latency.
Over decades, flash endures 100K cycles, outlasting electromechanical relays in harsh vaults. The GE IC695CRU320-EN forges redundancy that feels bulletproof.pdfsupply

Operational Guidance
Rack the GE IC695CRU320-EN in slot 1 of primary/standby main frames, installing RMX first for sync tests—match firmware, download identical programs, then enable reference mode via RUN switch. Wire serials shielded to programmers, verifying SNP handshakes pre-live; battery seats post-power-off, good for 6 months standby. Balance I/O loads across backplanes to hit scan targets.
Monthly diagnostics via LEDs/%S catch sync drifts; reseat modules in vibrating compressor houses. Firmware updates require both CPUs halted—snapshot retentives. This practice sustains the GE IC695CRU320-EN through fault-free years.
