I/O modules

The GE Fanuc IC697CPU771 functions as a central processing unit within the Series 90-70 PLC ecosystem. Emerson Automation now manages this module’s product lifecycle following the acquisition. This single-slot CPU delivers consistent processing performance for demanding industrial control environments.

Core Processing Capabilities

This module integrates an 80C186 microprocessor running at 12 MHz. Therefore, it achieves a Boolean execution speed of 0.4 microseconds per function. Such responsiveness makes it suitable for time-sensitive automation sequences requiring rapid scan cycles.

Memory Architecture and I/O Support

The GE Fanuc IC697CPU771 provides substantial memory allocation for diverse applications. It supports up to 512 KB of maximum RAM for program storage and data handling. For discrete I/O, it manages 2 KB of memory, while analog I/O utilizes 8 KB. This flexible configuration allows seamless integration with various field devices across the production floor.

Physical Specifications and Power Management

Weighing approximately 1.00 lbs (0.45 kg), this module occupies a single slot in the Series 90-70 rack. It features one serial port for programming or human-machine interface connections. Additionally, a built-in battery backup preserves program data and retains critical variables during power interruptions.

Technical Specifications

Installation and Compatibility

This CPU integrates directly into existing GE Fanuc 90-70 PLC chassis without modification. Its single-slot design conserves rack space for additional I/O or communication modules. Moreover, the consistent form factor simplifies system upgrades or replacements when maintaining legacy automation infrastructure.
