Engineers will appreciate the integrated design of the IC693CPU311J. This unit combines the processor and backplane into a single assembly. Consequently, users can build complete control systems without separate CPU and base components.

Furthermore, the 5-slot configuration accommodates up to five I/O or communication modules. This capacity suits small to medium automation projects efficiently. The IC693CPU311J provides 16 kilobytes of RAM for program execution and data storage.

Integrated Processor and Memory

The IC693CPU311J features a 16-bit processor with 0.5 millisecond per 1K logic scan time. This speed handles typical discrete and analog control applications effectively. The module includes 16 kilobytes of flash memory for program retention during power cycles.

The integrated backup battery maintains program integrity and real-time clock settings. Engineers can rely on this energy storage to protect valuable application data. The processor supports ladder logic programming through standard GE software tools.

System Integration and Communication

You can install this PLC base in standard industrial panels. The IC693CPU311J includes one RS-232 port for programming and operator interface connectivity. An additional RS-485 port supports Modbus communication with field devices.

The base accepts standard Series 90-30 modules in any of the five slots. Users can mix discrete, analog, and communication modules as application demands. For reference, other Series 90-30 components share this same module compatibility.

Power Requirements and Installation

The IC693CPU311J requires external 5V DC and 24V DC power supplies. The base distributes power to all installed modules through the backplane. Integrated mounting tabs simplify panel installation and secure the unit during operation.
