Detailed Feature Overview

This cassette stores up to 4 KB of user logic for machine control. It executes basic instructions in just 5 microseconds each. The unit supports 128 inputs and 128 outputs for medium-sized CNC applications.

A 1000 µF capacitor provides short-term energy buffering during power dips. With an optional lithium battery, data retention reaches about 30 days. Consequently, your PMC logic remains safe through brief outages.

You will find a 64-pin edge connector at the bottom of this unit. This connector interfaces directly with the CNC backplane bus. The scan time of 10 ms per 1K suits typical machine tool cycles.

Installation and Compatibility

GE A02B-0094-C102 fits PMC cassette slots in Fanuc CNC systems like Series 0, 15, or 18. Insert the cassette firmly until the latch clicks. Replace the lithium battery every two years for reliable backup.
