GE IC697PCM711P – Programmable Coprocessor Module (PCM)

In stock

Product Overview

The IC697PCM711P is a high-performance, single-slot programmable coprocessor module designed by GE Fanuc (Emerson) for the Series 90-70 PLC platform. It enhances PLC system capabilities by offloading complex processing, real-time computation, data management, and communication tasks, independent of the main PLC CPU. Multiple PCMs can operate in a single IC697 PLC system, making it ideal for advanced industrial automation requiring parallel task execution and expanded memory.
