Description
GE Fanuc IC697CPM790 PACSystems RX7i Control Processor for Industrial Automation
The GE Fanuc IC697CPM790 is a high-performance control processor module designed for GE’s PACSystems RX7i platform, delivering real-time automation control in critical industries such as energy, manufacturing, and water treatment. Engineered with a 600 MHz PowerPC processor and 1 GB RAM, this module supports complex logic execution, advanced motion control, and secure industrial networking, ensuring seamless integration in large-scale systems.
1. Product Overview
The IC697CPM790 serves as the brain of PACSystems RX7i, processing I/O data, executing ladder logic, and managing communication with field devices. Its dual Ethernet ports (10/100/1000 Mbps) enable redundant network connections, while SIL 3 compliance (with safety software) makes it ideal for safety-critical applications like oil refineries and power plants. With -40°C to +70°C operating range and hot-swap capability, the module minimizes downtime in harsh environments.
