Description
Product Description
The IC695CRU320 is a redundant CPU module for the PACSystems RX3i series, engineered to provide high availability and fault tolerance in critical industrial control systems. It supports dual-CPU redundancy configurations, ensuring uninterrupted operation for mission-critical applications in process control, power generation, and infrastructure automation.
This module features a 1 GHz Celeron M processor with 64 MB RAM and 64 MB non-volatile flash memory, capable of handling complex control programs across multiple racks. Built-in Ethernet (10/100 Mbps) and serial RS-232/RS-485 ports allow seamless integration with SCADA, HMI, and peer-to-peer networks. The IC695CRU320 is designed to occupy two RX3i slots and requires an external high-capacity battery (IC693ACC302) for memory backup during power loss.
