Description
The GE IC693CPU350-BC is a central processing unit (CPU) module from the legendary GE Fanuc Series 90-30 programmable logic controller (PLC) family. This module serves as the computational brain of the control system, executing user-programmed logic, managing data, and coordinating communication between all other I/O and specialty modules within the rack. The GE IC693CPU350-BC is specifically designed for robust and reliable performance in industrial environments, offering a perfect balance of processing power, memory capacity, and cost-effectiveness for a wide range of automation applications. It embodies the durability and long-term support that the Series 90-30 platform is known for, making it a trusted choice for both original equipment manufacturers and end-users maintaining existing installations.
As a cornerstone of the Series 90-30 system, the GE IC693CPU350-BC features an integrated RS-485 communication port, which is used for connecting programming devices (like a PC with Proficy Machine Edition software) and for configuring peer-to-peer network communications via SNP or RTU protocols. With 16K bytes of user logic memory, it is well-suited for medium-complexity control tasks in manufacturing, material handling, and infrastructure management. The module is designed for easy installation into a 5-slot or 10-slot 90-30 baseplate, where it automatically configures and manages the I/O system. Choosing the genuine GE IC693CPU350-BC ensures full compatibility, optimal performance, and preserves the integrity of your entire automation control strategy.
