GE Fanuc IC697CPM790 Series 90-70 CPU for Critical Applications

Product Overview

The IC697CPM790 is a single-slot CPU from GE Fanuc Series 90-70.

It is made for critical tasks like Emergency Shutdown, fire, and gas systems.

The CPU supports Triple Modular Redundancy (TMR) to prevent downtime.

It has a 64 MHz 80486DX2 processor and runs Boolean functions in 0.4 microseconds.

Memory includes 1 MB battery-backed RAM, with 512 KB for user programs.

It handles up to 12,000 discrete inputs and outputs in simplex mode.

Voted mode supports 2048 discrete inputs and outputs and 1024 analog inputs.

It supports up to 8K analog inputs and outputs in simplex mode.

Communication uses one 15-pin RS485 port.

Programming works with Windows or MS-DOS using ladder diagram or standalone C programs.
