GE IC695 (RX3i) Series: Comprehensive Module Range and Technical Overview

The GE IC695 series, commercially designated as the PACSystems RX3i, represents GE Automation & Controls' primary mid-to-high-end programmable logic controller platform. Deployed across global heavy industry — including petrochemical refineries, nuclear power auxiliary systems, offshore platforms, and continuous-process chemical plants — the RX3i backplane architecture supports mixed-media module insertion, enabling legacy IC693 (Series 90-30) coexistence within the same rack. Installed base spans North America, Europe, and Asia-Pacific, with documented deployments in facilities requiring IEC 61131-3 compliance and SIL-rated loop control. The IC695CBL001 specifically is the Energy Pack Cable, used to connect the RX3i CPU's energy pack (IC695ACC400) for capacitor-backed RAM retention during power loss events — a critical component in any RX3i CPU assembly.

The Evolution of IC695 (RX3i) Architecture

The PACSystems RX3i platform was introduced by GE Fanuc Automation in the early 2000s as a successor to the Series 90-30 (IC693) and Series 90-70 (IC697) families. The IC695 module numbering convention denotes RX3i-native hardware, while the universal backplane (IC695CHS012, IC695CHS016) accepts both IC695 and IC693 modules via a dual-bus architecture — a Universal Backplane Bus (UBP) for RX3i modules and a legacy PCI-compatible bus for Series 90-30 modules.

Key architectural milestones: the original CPE010/CPE020 CPUs (single-core, 32 MB user memory) were superseded by the CPE030/CPE040 generation with expanded memory and Ethernet embedded ports, then by the CPE100/CPE115/CPE302/CPE305/CPE310/CPE330/CPE400 line incorporating dual-port Ethernet, IEC 61850 support, and Linux-based runtime environments. The IC695CBL001 energy pack cable applies to CPE010, CPE020, CPE030, and CPE040 CPU variants. Later CPE302+ CPUs use integrated supercapacitor designs and do not require this cable. This lifecycle distinction is critical for maintenance planning: sites running pre-CPE302 CPUs must maintain IC695CBL001 and IC695ACC400 stock as long-term consumables.

Sourcing Hard-to-Find & Obsolete IC695 Parts

GE (now Emerson / Proficy) has transitioned several IC695 CPU variants — including the CPE010, CPE020, and CPE030 — to end-of-life status. OEM lead times for new-build replacements can exceed 20–40 weeks. DriveKNMS maintains a dedicated inventory of tested surplus and refurbished IC695 modules, with specific stock depth on high-attrition items including the IC695CBL001 energy pack cable, IC695ACC400 energy pack, and legacy CPU boards.

For facilities operating pre-CPE302 RX3i systems, DriveKNMS provides lifecycle extension support: module-level repair, functional testing against GE's original test specifications, and cross-reference advisory for compatible upgrade paths (e.g., CPE010 → CPE302 migration with backplane compatibility verification). All obsolete modules are sourced from decommissioned OEM-maintained facilities and carry full traceability documentation.

Quality Control for the IC695 Range

IC695 modules present specific test challenges due to the dual-bus backplane architecture and the energy pack subsystem. DriveKNMS applies the following test protocol to all IC695 inventory:

• Backplane bus integrity verification: UBP and legacy PCI bus signal continuity tested under load using a reference IC695CHS012 rack
• CPU modules: full firmware boot cycle, user memory read/write verification, Ethernet port link negotiation test (10/100 Mbps), and serial port loopback
• Energy pack cable (IC695CBL001): continuity test on all conductors; connector retention force check per GE mechanical specification
• Analog modules: calibration verification at 0%, 50%, and 100% of rated input/output range using traceable reference instruments
• Discrete I/O: point-by-point functional test under rated voltage and current; isolation resistance >100 MΩ at 500 VDC
• All modules: visual inspection for capacitor bulge, PCB corrosion, and connector pin damage prior to dispatch
