Description
Product Introduction
I’ve seen too many plants lose hours of production because a power flicker wiped their PLC memory. The GE IC695ACC400 is an energy bank module for PACSystem RX3i CPUs—specifically the CPE305 and CPE310 controllers . It provides enough temporary power during outages to transfer RAM contents to non-volatile Flash memory.This unit offers 10+ years of service life at 0-50°C, though that drops to just 4.5 years at 60°C . It connects via IC695CBL001 cable and mounts on the module’s left side, avoiding backplane slot consumption.

Quality Control Process (SOP Transparency)
We test energy packs like they’re going into a nuclear facility—because memory loss is that critical. Here is the sequence.
- Incoming Verification: Validate part number against Emerson database. Check manufacturing date code—service life starts at manufacture, not installation. Inspect Samtec connector pins for alignment and gold plating integrity.
- Live Functional Test: Connect to test CPE310 CPU using IC695CBL001 cable. Simulate power loss with controlled DC supply cutoff. Verify CPU successfully writes test program to Flash before energy pack depletes. Monitor status LEDs throughout cycle.
- Electrical Parameter Test: Measure insulation resistance at 500 V between cable conductors and casing (>100 MΩ). Check continuity on both power and ground paths. Verify charging circuit activates within 2 seconds of power restoration.
- Firmware Verification: No firmware, but record capacitor bank manufacturing batch code. Photograph status LED patterns during charge and discharge cycles.
- Final QC & Packaging: Inspector signs off after confirming full discharge/recharge cycle. Seal in anti-static bag with desiccant. Bubble wrap and carton with QC label showing test date and remaining capacity percentage.

Replacement Pitfall Guide (Field Engineer’s Warnings)
The GE IC695ACC400 looks simple but has subtle failure modes that bite you later. Keep these five points in mind and you’ll eliminate roughly 90% of rework.
- ❗ Temperature Degradation: Service life halves at 60°C . Case: An engineer installed this unit near a transformer—ambient heat cut its life from 10 years to under 5. Measure enclosure temperature first.
- ❗ CPU Compatibility Lock: Only works with CPE305 and CPE310 . “Trying to use it with a CPE302 or later CPUs like the 320-series will fail silently—the CPU won’t recognize the pack.”
- ❗ Cable Length Matters: The IC695CBL001 comes in 3 m and 0.91 m versions . Using a shorter cable than specified creates voltage drop during discharge—the CPU might not get enough power to complete the Flash write.
- ❗ Mounting Position Critical: Install in slot 0 to avoid backplane interference . Mounting elsewhere can block cooling airflow or prevent adjacent module removal during maintenance.
- ❗ Shelf Life Awareness: The 10-year clock starts at manufacture, not installation. Check the date code; a unit stored for 3 years already has 30% less usable life remaining.
