Product Overview

The GE Fanuc IC693CPU331 serves as the central processing intelligence for the Series 90-30 PLC platform. Designed for mid-range industrial applications, it executes logic and manages system-wide I/O synchronization with high consistency. We offer this module as 100% Brand New, providing a critical lifeline for maintaining and extending the service life of existing Series 90-30 architectures. It utilizes an Intel 80188 processor to manage up to 512 discrete I/O points, making it a robust choice for material handling, packaging, and general machine control.

Technical Specifications

The following parameters define the performance and memory architecture of the IC693CPU331:

Engineering Advantages

• Deterministic Logic Execution: The 10 MHz Intel processor ensures a predictable 0.4 ms scan rate for Boolean instructions. This precision allows engineers to maintain tight control loops in synchronized manufacturing processes.

• Scalable Architecture: The IC693CPU331 supports up to four expansion baseplates. This enables the system to grow alongside your facility's requirements without needing a complete overhaul of the central processor.

• Robust Memory Management: The 16 KB of user memory accommodates complex logic and extensive register data (%R). By utilizing battery-backed RAM or optional EPROM/EEPROM, the module prevents data loss during power cycles, ensuring the PLC recovers instantly upon restart.

• Simplified Maintenance: As a single-slot module, the IC693CPU331 allows for rapid physical replacement. Its compatibility with the standard Series 90-30 power supply SNP port simplifies serial communications and programming tasks.

FAQs

• Can the IC693CPU331 store the user program without a battery?

  While the module uses battery-backed RAM for volatile storage, you can utilize an optional EPROM or EEPROM chip for non-volatile storage. This ensures the program remains intact even if the battery fails during a long-term shutdown.

• How do I connect a programming terminal to this CPU?

  The IC693CPU331 communicates through the SNP port located on the system power supply. You must install the CPU in the first slot of the baseplate adjacent to the power supply to enable this communication path.

• Is this module compatible with newer Emerson Series 90-30 components?

  Yes. Although Emerson now manages the GE Fanuc line, the IC693CPU331 maintains full hardware and software compatibility with standard Series 90-30 I/O modules and baseplates.

• What is the maximum number of timers and counters available?

  The module supports up to 680 internal timers and counters, providing ample resources for complex sequencing and duration-based logic in industrial environments.
