Description
🔹 Product Overview
The GE Fanuc IC695CRU320CA-EL is a PACSystems RX3i Redundancy CPU Module designed for high-availability industrial automation and control applications. The CRU320 platform uses a 1 GHz processor and supports redundant CPU operation, allowing primary and standby controllers to exchange system data through compatible redundancy synchronization modules.
The module provides two independent serial communication ports supporting RS-232 and RS-485, together with RX3i PCI and high-speed serial backplane interfaces. It supports up to 64 MB of battery-backed RAM and 64 MB of non-volatile flash user memory, making it suitable for PLC control programs, industrial sequencing, process automation, and system replacement applications.

⚙️ Application
The IC695CRU320 platform is intended for PACSystems RX3i control architectures where CPU redundancy and rapid controller switchover are required. It can be integrated with compatible RX3i racks, I/O modules, communication hardware, and IC695RMX128/228 redundancy synchronization modules. The documented minimum switchover time is 3.133 ms, with a maximum of one logic scan under the specified redundancy configuration.
🛠️ Replacement Notes
Before installation, verify the complete IC695CRU320CA-EL ordering code, hardware revision, firmware compatibility, rack configuration, redundancy architecture, and existing CPU setup. The CA-EL suffix should be matched against the installed system documentation rather than assuming interchangeability with every IC695CRU320 revision.
