Product Overview

The GE Fanuc IC697CPU789 is a high-reliability, single-slot CPU module specifically engineered for Triple Modular Redundancy (TMR) systems. Operating on a 32-bit 80386DX processor at 16 MHz, this unit is the core of fault-tolerant control architectures, utilizing majority-voting logic to ensure seamless operation even in the event of a hardware failure. With a compact physical profile and a net weight of only 0.42 kg, the IC697CPU789 delivers industrial-grade integrity for high-stakes automation environments where system downtime is not an option.

Technical Specifications

Parameter Specification
Brand GE Fanuc
Model Number IC697CPU789
Processor Type 80386DX @ 16 MHz

Engineering Advantages

  • Triple Modular Redundancy (TMR): The IC697CPU789 hardware is optimized for three-unit synchronization, providing superior fault tolerance compared to standard simplex CPUs.
  • Lightweight Integration: At just 0.42 kg, this module fits into a single VME-compatible rack slot, allowing for high-density redundancy configurations without excessive mechanical load.
  • High Integrity I/O: Supports up to 2,048 voted discrete inputs and outputs, ensuring that field data is verified across redundant modules before logic execution.

Installation & Connectivity

The GE Fanuc IC697CPU789 features a standard VME-compatible footprint (180 × 100 × 25 mm) for easy rack integration. Communication is handled via a high-speed serial port supporting RS-422/RS-485 at rates up to 115,200 bps. Given its 0.42 kg weight, it is easily installed into Series 90-70 backplanes. Technicians should ensure the battery is checked annually to maintain the 512 KB data retention during power-off periods.
