Product Introduction

GE is the baseline high-performance standalone controller for the PACSystems RX3i platform, widely deployed in general industrial automation. It occupies only one rack slot, saving chassis space for I/O and communications modules. It supports seamless migration of legacy Series 90‑30 I/O modules, lowering retrofit investment. When paired with IC695RMX128 fiber modules in separate racks, it can form hot standby redundant control systems to avoid unplanned downtime. Dual serial ports enable direct connection to Modbus field instruments, local HMIs and legacy serial equipment. All TCP/IP Ethernet communication relies on external IC695ETM001 series Ethernet modules. Single-slot form factor supports direct drop-in spare replacement during planned maintenance windows.

Key Selling Points & Differentiators

1. GE is the baseline standard-temperature RX3i CPU, balanced performance for most general process and machine automation projects.
2. Single-slot design conserves rack space compared to two-slot dedicated redundant IC695CRU320 CPU.
3. Every unit undergoes full bench validation on an RX3i test chassis; program download, serial protocol testing, redundancy initialization simulation and LED diagnostics verified prior to shipment. Signed test documentation available on formal request. Warranty runs 12 months post delivery.
4. Native ANSI C support enables complex algorithmic control beyond standard ladder logic.
5. Not compatible with RX7i, Series 90‑70 or Series 90‑30 main racks; designed exclusively for RX3i universal backplane architecture.
6. Backward compatible with Series 90‑30 I/O modules, ideal for legacy control system upgrade projects.

Quality Transparency SOP

• Incoming Verification: Serial traceability validation, anti-counterfeit visual inspection, D-Sub serial port and battery socket hardware cross-check.
• Live Bench Test: Dedicated RX3i test rack, power-on self-test, full program download validation, Modbus serial master/slave test, continuous 24-hour thermal soak cycling.
• Electrical Tests: 500 V megger insulation resistance testing, backplane power rail stability verification.
• Hardware Verification: Confirm LED array and serial communication circuits operate per datasheet; no unauthorized component rework performed.
• Final QC & Packaging: Anti-static shielding, shock-dampened transit carton, signed QC Pass label. Test images and logs available on request. No zero-failure performance guarantee.

Technical Risk Avoidance Section

Suffix Variant Mismatch Risk Risk: Deploying standard into cold unheated cabinets or poorly ventilated high-temperature enclosures leads to unstable operation. Prevention:

• Use for high-speed scan machine applications
• Use IC695CPU320HU for extended temperature (-25~+70°C) sites Field note: Multiple remote pumping stations experienced periodic communication faults after installing standard CPU320 in non-air-conditioned field cabinets.

CPU320 vs CRU320 Architecture Confusion Risk Risk: Attempting single-slot as direct replacement for two-slot IC695CRU320 redundant CPU without rack layout review. Prevention: IC695CRU320 is dedicated two-slot redundant CPU; is single-slot standalone CPU. They cannot directly substitute without project and rack redesign.

Backup Battery Expiry Risk Risk: Aging IC695ACC302 lithium battery loses RAM and RTC data retention after extended power outages. Schedule battery replacement concurrent with CPU exchange.

ESD Damage Risk Risk: Unprotected handling damages memory and communication circuits without immediate visible fault indicators. Prevention: Use grounded wrist straps; keep module sealed inside anti-static packaging until rack insertion.

Critical Summary: Confirm cabinet operating temperature, control scan performance requirements and rack slot layout before procurement. This is a single-slot standalone standard CPU, cannot be directly substituted with two-slot IC695CRU320 without rack layout and redundancy scheme redesign. Operates exclusively on RX3i universal backplanes.

FAQ

1. Q: Can GE be installed into RX7i or Series 90‑70 racks? A: No. Built exclusively for RX3i universal backplanes; mechanical and electrical interfaces incompatible with other GE PLC families.
2. Q: What are the differences between / -HS / IC695CPU320HU? A:

• : Standard grade, 0 ~ +60°C, standard timing
• : Standard temp 0 ~ +60°C, factory high-speed tuning for shorter logic scans
• IC695CPU320HU: Extended rugged grade -25 ~ +70°C, standard timing Core memory, instruction set and communication functions are identical.

1. Q: Can be used for RX3i hot standby redundant systems? A: Yes. Requires IC695RMX128 fiber reflective memory module installed in each rack, dual independent chassis architecture.
2. Q: Does this module support hot-swap replacement while the RX3i rack remains energized? A: Hot swap is not supported. Isolate rack power supply before removing or installing the CPU.
3. Q: What lead times apply for available inventory? A: In-stock units ship within 1–3 business days. Backordered allocations require 5–7 week lead times subject to global surplus availability.
4. Q: What failure modes fall outside warranty coverage? A: The 12-month limited warranty covers manufacturing defects. Damage from expired backup battery, ESD, improper serial wiring, and operation outside published temperature range is excluded.
5. Q: What is the core difference between and IC695CRU320-CD/EH? A:

• : Single-slot standalone CPU, optional redundancy with RMX128
• IC695CRU320: Two-slot dedicated redundant-only CPU, optimized for bumpless hot standby failover They cannot directly substitute each other without rack layout and project rework.
