Overview

The GE IC693CPU341 is a Central Processing Unit (CPU) module from the Series 90-30 family of Programmable Logic Controllers (PLCs). This module functions as the "brain" of the PLC system, responsible for:

• Processing user logic
• Executing control programs
• Communicating with other modules
