Processing Power and Memory

The GE IC693CPU374-GP runs a 25 MHz 32-bit processor for fast ladder execution. You get 240 KB of user memory for storing programs and register data. A lithium battery preserves all memory contents during power outages. This battery lasts approximately five years under normal conditions.

I/O Capacity and Expansion

This CPU supports up to 4096 discrete inputs and 4096 discrete outputs. You can also manage 1024 analog inputs along with 1024 analog outputs. Moreover, the module works with any Series 90-30 I/O rack. Consequently, you can build systems with hundreds of field devices.

Communication Interfaces

A built-in RS-232 port connects directly to a programming laptop. The second RS-485 port supports SNP or RTU protocols for HMI links. Additionally, you can install an expansion card for Ethernet or Profibus connectivity. This flexibility allows seamless integration into existing factory networks.

Performance and Scan Time

The unit scans 1K of Boolean logic in just 0.4 milliseconds. This fast scan rate handles complex control algorithms without any lag. Furthermore, the CPU supports up to 512 program blocks. You can organize your code into subroutines for easier maintenance.

Installation and Compatibility

Mount this CPU in the first slot of a Series 90-30 rack. It replaces older IC693CPU374 models without any wiring changes. The module draws only 500 mA from the backplane supply. For best results, upgrade your programming software to Version 6.0 or higher.

Why Choose This CPU

This processor bridges the gap between micro and large PLC systems. Its memory capacity handles most machine control tasks comfortably. Therefore, manufacturers choose this CPU for packaging lines and assembly stations.
