Product Introduction
The GE IC693CPU313 is a Series 90-30 component from GE Fanuc, integrating a Turbo CPU directly into a 5-slot baseplate. This design eliminates the need for a separate CPU module, simplifying system architecture. The baseplate hosts up to five I/O modules and one power supply, making it a compact solution for small to medium control tasks. With an 80188 processor clocked at 10 MHz and a typical scan rate of 0.6 milliseconds per 1K of logic, the IC693CPU313 delivers reliable performance for discrete and analog control applications.

Industry Applications
The GE IC693CPU313 is well-suited for legacy industrial control systems that require a compact, self-contained PLC. Common applications include:
-
Machine Control: In packaging, material handling, or assembly machines, the IC693CPU313 handles up to 160 discrete I/O points and 64 analog words, suitable for monitoring sensors and controlling actuators.
-
Process Monitoring: With analog I/O capacity, it can interface with transmitters for temperature, pressure, or flow, making it ideal for small batch processes in chemical or food industries.
-
Remote I/O Stations: When used as a remote baseplate connected via SNP protocol, the IC693CPU313 can distribute control logic to remote locations, reducing wiring costs.
Compatibility and Integration
The IC693CPU313 is part of the GE Series 90-30 family. It accepts standard Series 90-30 I/O modules, including discrete, analog, and specialty modules. The built-in serial port supports SNP (slave) and SNP-X slave protocols, allowing communication with GE PLCs or HMIs. Note that this baseplate does not support PCM or CCM modules, nor can it be expanded with additional baseplates. It is designed as a standalone controller. For new installations, consider upgrading to a modern GE RX3i system, but the IC693CPU313 remains a reliable spare for existing lines.
Selection Guide and Purchasing Advice
When sourcing the GE IC693CPU313, verify that your system operates in the specified temperature range (32–140 °F) and that the power supply slot can accommodate a compatible unit (e.g., IC693PWR321). The baseplate requires a +5 VDC bus at 410 mA. Since this part is discontinued, ensure you buy from a trusted supplier with tested inventory. At UBEST Automation (ubest101), we stock quality-tested IC693CPU313 units with accurate specifications. Contact our team to confirm compatibility with your existing I/O modules before ordering.
