GE Fanuc IC695CPU320 High-Performance PACSystems RX3i Controller
The GE Fanuc IC695CPU320 is a high-performance central processing unit (CPU) module designed for GE Fanuc’s PACSystems RX3i platform, delivering advanced control capabilities for industrial automation, power generation, and process control applications. As part of GE’s modular automation ecosystem, the IC695CPU320 supports real-time data processing, multi-protocol communication, and scalable I/O integration, making it ideal for mission-critical environments such as oil & gas refineries, water treatment plants, and automotive assembly lines.
1. Product Overview
TheIC695CPU320 serves as the core controller for PACSystems RX3i systems, enabling seamless integration with GE’s Series 90-30 I/O modules and modern industrial protocols. Its 1 GHz Celeron M processor and 64 MB RAM + 64 MB NVRAM ensure rapid execution of complex control logic, while dual RS-232/RS-485 ports and PCI backplane connectivity facilitate high-speed data transfer. With hot-swap capability and -40°C to +60°C operating range, the module minimizes downtime in harsh industrial settings.
