GE IC695CBL001 Replacement Cable for PACSystems RX3i

Product Overview

GE IC695CBL001 Replacement Cable for PACSystems RX3i: Smooth Transition & Legacy System Compatibility

When your PACSystems RX3i control system depends on a reliable energy pack interconnect cable, a failed or discontinued IC695CBL001 can bring an entire production line to a halt. The GE IC695CBL001 is the factory-specified Energy Pack Interconnect Cable designed for the GE PACSystems RX3i platform — connecting the IC695ACC402 Energy Pack module to the CPU backplane and ensuring uninterrupted battery-backed memory retention during power loss events. Whether you are replacing a worn cable in an aging RX3i rack, upgrading from an earlier PACSystems Series 90-70 architecture, or sourcing a verified spare to reduce unplanned downtime, the IC695CBL001 is a direct, plug-and-play solution that requires no firmware changes, no re-programming, and no wiring modifications to your existing control cabinet.

For facilities migrating from legacy GE Series 90-70 PLCs — including systems built around the IC697CPU772 or IC697CPU781 processors — to the modern PACSystems RX3i platform, the IC695CBL001 is a critical component in the transition. The RX3i backplane architecture, including the IC695CHS012 and IC695CHS016 rack assemblies, uses a standardized connector layout that the IC695CBL001 is engineered to match precisely. Engineers performing rack-level retrofits will find that the cable’s connector pitch, shielding, and length are optimized for the RX3i chassis form factor, eliminating the need for custom cable fabrication or field modifications.

In modernization projects where the IC695PSA140 or IC695PSD140 power supply modules are being retained alongside a new IC695CPU320 or IC695CPU310 processor, the IC695CBL001 ensures that the energy pack circuit remains intact across the upgrade boundary. This is particularly important in applications where the RX3i CPU must maintain program memory and retentive data registers during a controlled power-down sequence — a requirement common in water treatment, oil & gas, and discrete manufacturing environments. The cable’s role in the energy pack circuit means that substituting an incorrect or non-OEM cable can result in memory loss faults, CPU diagnostic errors, or failed warm-restart sequences.

For control system integrators managing multi-rack RX3i configurations, the IC695CBL001 is also relevant when expanding an existing system with additional IC695CHS007 expansion racks connected via the IC695LRE001 Local Rack Expansion cable. In these architectures, each CPU rack requires its own energy pack and interconnect cable to maintain independent memory backup. Sourcing verified IC695CBL001 units for each rack in a multi-rack system is a standard best practice recommended during both initial commissioning and scheduled preventive maintenance cycles.

Communication module compatibility is another consideration during RX3i migration projects. Systems incorporating the IC695ETM001 Ethernet module, the IC695PBM300 PROFIBUS Master module, or the IC695CMM002 Serial Communications module rely on the CPU’s retentive memory to store network configuration parameters and communication table data. A properly functioning IC695CBL001 ensures that these communication settings survive power interruptions without requiring a full re-download from the programming workstation running Proficy Machine Edition. This reduces commissioning time and eliminates the risk of configuration mismatch errors after an unplanned power event.

Field engineers performing hot-standby redundancy upgrades using the IC695RMX128 Redundancy Memory Xchange module will also encounter the IC695CBL001 as part of the primary CPU rack assembly. In redundant RX3i configurations, both the primary and secondary CPU racks require independently verified energy pack cables to ensure that switchover events do not result in memory loss on either controller. Sourcing matched pairs of IC695CBL001 cables is a recommended practice for redundancy system commissioning and annual maintenance inspections.

From a physical installation standpoint, the IC695CBL001 is designed for tool-free connection to the IC695ACC402 Energy Pack module and the corresponding CPU backplane port. The cable’s keyed connectors prevent incorrect insertion, and the cable length is factory-optimized for standard RX3i rack depths. No additional cable management hardware is required for a standard single-rack installation. For retrofit projects where the original cable has been damaged by heat, vibration, or chemical exposure in harsh industrial environments, the IC695CBL001 is available as a direct spare with no modification to the surrounding wiring harness or control cabinet layout.

Seamless Upgrade Solutions

A complete PACSystems RX3i migration or retrofit typically involves more than a single cable. When sourcing the IC695CBL001, system integrators commonly address the following components in the same procurement cycle to minimize return visits and reduce total project downtime.

The IC695ACC402 Energy Pack is the capacitor-based backup module that the IC695CBL001 connects to the CPU backplane. If the energy pack itself has reached end-of-life — indicated by a BATT fault on the IC695CPU320 or a failed self-test during power-up — replacing both the IC695ACC402 and the IC695CBL001 together is the recommended approach to restore full memory backup functionality. Similarly, the IC695PSA140 AC Power Supply is frequently evaluated during RX3i rack refurbishment projects; a degraded power supply can cause intermittent voltage sags that accelerate energy pack discharge cycles, making the cable and power supply a logical paired replacement.

For projects involving communication system upgrades, the IC695ETM001 Ethernet Transmitter Module is often added to RX3i racks during migration from Series 90-70 systems that relied on serial SNP communications. The IC695ETM001 enables EtherNet/IP and SRTP connectivity, and its network configuration is stored in the CPU’s retentive memory — protected by the IC695CBL001 energy pack circuit. In PROFIBUS-based plant networks, the IC695PBM300 PROFIBUS Master Module serves a similar role, storing slave device tables and GSD configurations in retentive memory that the energy pack preserves during power interruptions.

Physical rack infrastructure is another common procurement item. The IC695CHS012 Universal Backplane (12-slot) and the IC695CHS016 (16-slot) are the standard rack assemblies for RX3i CPU and I/O module installations. When a rack is being replaced due to physical damage or slot capacity expansion, the IC695CBL001 must be re-routed and re-connected as part of the rack swap procedure. I/O module sourcing — including the IC695MDL654 Discrete Output Module and the IC695ALG600 Analog Input Module — is typically consolidated into the same purchase order to reduce freight costs and simplify incoming inspection at the plant site.

Finally, for engineers who need to re-download or verify CPU configuration after a cable replacement, the IC690USB901 USB-to-Serial Programming Cable (or its RX3i-compatible equivalent) is an essential field tool for connecting a Proficy Machine Edition workstation to the IC695CPU310 or IC695CPU320 serial port. Having a verified programming cable on-site before beginning a cable replacement procedure ensures that any post-replacement diagnostics or program re-downloads can be completed without delay.

Retrofit Guidance FAQ

Q: Can the IC695CBL001 be used as a direct replacement without any wiring changes?
A: Yes. The IC695CBL001 uses keyed connectors that mate directly with the IC695ACC402 Energy Pack and the RX3i CPU backplane port. No wiring modifications, crimping, or custom fabrication are required. Simply disconnect the old cable, inspect the connector seats for debris or corrosion, and insert the replacement cable until both connectors click into the locked position.

Q: Will replacing the IC695CBL001 require a program re-download to the CPU?
A: In most cases, no. If the IC695ACC402 Energy Pack retains sufficient charge during the cable swap — which is typical when the swap is performed within the energy pack’s hold-up time window — the CPU will retain its program and retentive data. However, if the energy pack has been fully discharged prior to the replacement, a program re-download from Proficy Machine Edition will be required. It is recommended to perform the cable replacement with the CPU in STOP mode and to verify the energy pack charge level before beginning.

Q: Is the IC695CBL001 compatible with all RX3i CPU variants?
A: The IC695CBL001 is compatible with all IC695 series CPUs that support the IC695ACC402 Energy Pack, including the IC695CPU310, IC695CPU315, IC695CPU320, and IC695CPUE030. It is not compatible with Series 90-70 (IC697) CPUs or with the PACSystems RSTi-EP platform, which uses a different energy backup architecture.

Q: What communication protocols are supported after replacing the cable?
A: The IC695CBL001 has no direct effect on communication protocol support — it is a power and signal cable for the energy pack circuit only. All communication protocols supported by the installed CPU and communication modules (including EtherNet/IP, SRTP, PROFIBUS DP, Modbus TCP, and serial SNP/SNPX) remain fully operational after cable replacement. The cable replacement does not require any changes to the CPU’s communication configuration tables.

Q: How much physical space does the IC695CBL001 require inside the control cabinet?
A: The IC695CBL001 is factory-sized for standard RX3i rack installations and requires no additional cable management hardware. The cable routes between the IC695ACC402 module slot and the CPU backplane port within the rack assembly itself, with minimal protrusion into the surrounding cabinet space. For tight cabinet installations, ensure that the cable bend radius is not less than the manufacturer’s minimum specification to avoid connector stress.

Q: Can the IC695CBL001 be used in a redundant RX3i system?
A: Yes. In hot-standby redundant RX3i configurations using the IC695RMX128 Redundancy Memory Xchange module, each CPU rack (primary and secondary) requires its own IC695CBL001 and IC695ACC402 Energy Pack. The cables are independent and do not interact with the redundancy switchover logic. Both cables should be replaced simultaneously during scheduled maintenance to ensure matched energy pack backup performance across both controllers.
