Available with express worldwide shipping and 12-month warranty.
What Is the IC695CPK330?
The IC695CPK330 is a Central Processing Unit (CPU) module for the GE Fanuc PACSystems RX3i platform, and the direct energy-pack-equipped variant of the IC695CPE330. Its defining feature over the standard CPE330 is the integrated Energy Pack, which maintains volatile memory content during unexpected power outages — allowing the controller sufficient time to transfer RAM data to non-volatile flash storage before shutting down, eliminating the need for a conventional battery backup. The IC695CPK330 runs on a 1 GHz Dual Core processor (some supplier sources cite 1.6 GHz for certain hardware revisions), provides 64 MB of user logic RAM, and supports two independent Gigabit Ethernet LANs. It is programmed using Proficy Machine Edition (PME) software and supports the full range of RX3i I/O, motion, and intelligent option modules. Now maintained by Emerson Automation following the 2019 acquisition of GE Intelligent Platforms, the IC695CPK330 remains actively deployed in manufacturing, oil and gas, power, and water treatment facilities worldwide.

Energy Pack Functionality and Battery-Less Operation
The Energy Pack integrated with the IC695CPK330 is the key differentiator from the IC695CPE330. During a power interruption, the Energy Pack supplies up to 45 Watts to the CPU module for a brief period, allowing the controller to gracefully transfer the contents of volatile RAM to internal non-volatile flash memory. Upon power restoration, the CPU reloads the saved program and data state, resuming operation without requiring a full cold-start initialization. Firmware for the Energy Pack is automatically updated by the controller at power-up when a newer version is available — no manual firmware management is required. The Energy Pack has a rated five-year life expectancy under normal operating conditions and must not be installed in direct sunlight or in environments exposed to rain, liquids, or corrosive gases. The compatible Energy Pack for the CPK330 / CPE330 is the IC695ACC402 — do not attempt to use the IC695ACC400 (designed for CPE305/310) or the ICRXIACCEPK01 RXi Energy Pack, as these are electrically incompatible and may prevent the CPU from powering up.
Expert Tips
When migrating from an older Series 90-30 CPU374 to the IC695CPK330 in an existing RX3i rack, verify that all installed I/O modules have IC694 or IC695 catalog prefixes — Series 90-30 main rack I/O is not directly interchangeable with RX3i I/O modules even though the physical form factors appear similar. For PROFINET I/O integration, the IC695CPK330 requires the IC695PNC001 PROFINET Controller module — the CPU’s embedded Ethernet ports do not natively support PROFINET I/O scanner functionality. When configuring Hot Standby Redundancy with the IC695CPK330, ensure the companion redundancy CPU is an IC695CRU320 and that the IC695PSA140D or higher revision AC power supply is installed if using AC input — earlier PSA140 revisions may cause compatibility issues with the CPE330/CPK330 family as noted in GE Fanuc field advisory documentation. Always set the CPU compatibility mode (Normal vs. CRU320) in PME before downloading a redundancy application — the factory default is Normal (CPU320) mode.
Frequently Asked Questions
Q: What is the difference between the IC695CPK330 and the IC695CPE330?
A: The IC695CPK330 includes an integrated Energy Pack for battery-less volatile memory protection during power outages. The IC695CPE330 does not include the Energy Pack. Both share the same processor architecture, memory, and Ethernet specifications. If continuous memory retention during power interruptions is required, the CPK330 is the correct choice.
Q: Which Energy Pack is compatible with the IC695CPK330?
A: The only compatible Energy Pack is the IC695ACC402. The IC695ACC400 (for CPE305/310) and the ICRXIACCEPK01 (RXi platform Energy Pack) are not compatible and must not be used with the CPK330 or CPE330 — connecting the RXi Energy Pack will cause the CPU to continuously reset and fail to power up.
Q: Can the IC695CPK330 be used in a Hot Standby Redundancy configuration?
A: Yes, when paired with an IC695CRU320 redundancy CPU and the appropriate RMX modules. However, firmware must be updated to version 8.80 or later to enable Achilles Level 2 Communications Security Certification and Hot Standby Redundancy with Ethernet support. Verify firmware compatibility in PME before commissioning.
