Product Overview

The GE Fanuc IC693CPU352 functions as the high-tier computational engine for the Series 90-30 PLC family. Built on the 80386EX architecture with a 25 MHz clock speed, this single-slot CPU manages sophisticated automation tasks that require extensive memory and high-speed data manipulation. We supply this module as 100% Brand New and Original, ensuring your control system utilizes factory-fresh hardware capable of executing 240 Kbytes of user program with deterministic precision.

Technical Specifications

Engineering Advantages

• Hardware-Accelerated Math: The IC693CPU352 features a built-in hardware math co-processor. This dedicated silicon handles complex floating-point calculations independently, preventing the "scan-time lag" often encountered when using software-emulated math in lower-tier CPUs. This capability proves essential for high-accuracy PID loops and analog signal scaling.

• Superior Communication Density: This module provides three serial ports. Port 1 and Port 2 support RTU slave and SNP/SNP-X master/slave protocols, while the PLC power supply port handles standard SNP communication. This allows the CPU to interface with multiple HMIs, drives, and SCADA systems simultaneously without requiring additional communication cards.

• Large-Scale Addressing: The CPU addresses up to 2048 discrete I/O points and a massive 32,640 analog I/O words. This scalability allows for the control of extensive plant sections, such as chemical dosing systems or multi-conveyor packaging lines, within a single 90-30 rack configuration.

• Deterministic Logic Execution: With a typical scan rate of 0.22 ms per 1K of Boolean logic, the IC693CPU352 provides the high-speed throughput required for fast-acting machinery. It maintains consistent timing even as the user program approaches the 240 Kbyte memory limit.

• Massive System Expansion: The CPU supports up to seven extension or remote baseplates. This allows for distributed I/O architectures that span several cabinets, reducing field-side wiring costs while keeping the high-speed processing centralized.

FAQs

• How does the IC693CPU352 compare to the CPU351?

  The CPU352 utilizes a more powerful 80386EX processor and includes an integrated math co-processor for hardware-based floating-point math, whereas lower models may rely on software emulation which is significantly slower for complex calculations.

• Can I use this CPU with older Series 90-30 baseplates?

  Yes. The IC693CPU352 maintains full compatibility with standard 5-slot and 10-slot 90-30 baseplates. However, to leverage the full 7-rack expansion capability, ensure your power supplies and cables meet the latest hardware revision standards.

• What protocols do the serial ports support?

  The ports support SNP and SNP-X (slave/master) as well as RTU Slave. This allows the CPU to integrate seamlessly with GE Proficy software, QuickPanel HMIs, and third-party Modbus RTU masters.

• Why is "Brand New" condition critical for this legacy module?

  The Series 90-30 is a discontinued but widely utilized platform. Used or "refurbished" CPUs often carry degraded internal memory batteries and aged electrolytic capacitors that fail under high heat. A 100% Brand New IC693CPU352 ensures a fresh 80386EX processor and pristine internal components, providing the 10+ year service life required for critical industrial infrastructure.
