GE IC697CPM790 Triple Modular Redundancy (TMR) Control System

Industrial-Grade Reliability for Critical Automation

The GE IC697CPM790 is a fault-tolerant PLC CPU designed for mission-critical industrial automation. Its Triple Modular Redundancy (TMR) architecture ensures maximum operational uptime in demanding environments.

Core Specifications

• Product Type: CPU
• Microprocessor: 64 MHz 80486DX2
• Installation Slots: 1
• Status LEDs: 4 indicators
• Communication Port: 15-pin sub-D (RS485)
• Serial Protocol: RS485

Key Technology: Triple Modular Redundancy

The TMR system uses three parallel processors executing identical tasks. Voting logic compares outputs in real-time to detect and correct faults before they impact operations. This delivers:

• ▶︎ 99.999% uptime in critical processes
• ▶︎ Automatic error correction without system interruption
• ▶︎ Protection against single-point failures
