IC697CPU731 | GE Fanuc Series 90-70 Central Processing Unit Module

Product Overview

The GE Fanuc IC697CPU731 serves as the primary logic engine for the Series 90-70 programmable controller platform. This single-slot CPU module executes complex control algorithms and manages high-density I/O configurations across the VME-based backplane. It integrates a 12 MHz processor with 32 Kilobytes of fixed-size CMOS RAM, providing a stable environment for mid-range automation tasks. We supply this unit in 100% Brand New condition, ensuring peak performance for legacy system maintenance and infrastructure longevity.

Technical Specifications

Engineering Advantages

• Optimized I/O Management: The IC697CPU731 effectively controls up to 512 discrete I/O modules and an expansive 8,000 analog points. This high analog ceiling makes it particularly effective for process control applications involving extensive instrumentation and sensor arrays.

• Simplified Hardware Interface: The module features a physical three-position operation mode switch. This allows maintenance personnel to toggle between "Run with Outputs Enabled," "Run with Outputs Disabled," and "Stop" modes directly at the rack, facilitating safe onsite testing and commissioning without a PC.

• Reliable Data Retention: A high-capacity lithium battery protects the 32KB CMOS RAM. This system preserves critical logic and register data for up to six months during total power loss, preventing costly re-programming and downtime after extended facility shutdowns.

• Precision Timing Control: The internal hardware clock maintains high accuracy with a drift of only ±3.5 seconds per day. This precision ensures that time-stamped diagnostic data and scheduled process events remain synchronized across the control network.

FAQs

• How do I connect a programming terminal to the IC697CPU731?

  You access the CPU via the built-in RS-422/RS-485 serial port. This port supports SNP (Series Ninety Protocol), allowing direct connection to a PC running Proficy Machine Edition or Logicmaster 90 software using the appropriate converter cable.

• Can I upgrade the memory capacity of this specific model?

  The IC697CPU731 features a fixed 32KB CMOS RAM architecture. If your application logic exceeds this limit, you must migrate to a higher-tier CPU in the Series 90-70 line, such as the IC697CPU771 or higher.

• What maintenance does the lithium battery require?

  The lithium battery has a shelf life of 10 years at 20°C. However, we recommend replacing the battery every 2 years during scheduled maintenance to ensure the 6-month memory retention window remains valid.

• Is this a refurbished or used pull?

  No. We guarantee this IC697CPU731 is 100% Brand New and unused. This ensures the internal CMOS chips and electrolytic components have zero hours of thermal wear, providing the highest possible Mean Time Between Failures (MTBF).
