Product Overview
The GE IC693ACC305 IC Chips are EEPROM memory modules designed for the GE Series 90-30 PLC system. These chips are used to store and retain program data, enabling PLC systems to maintain logic integrity even without continuous battery backup.
This module is commonly installed in the CPU or backplane “PROGRAM PROM” socket, where it supports program storage, duplication, and recovery functions in industrial automation systems.
It is widely used in maintenance, commissioning, and system backup applications where secure and non-volatile program storage is required.

Function and Working Principle
The IC693ACC305 operates as a non-volatile memory storage unit within GE PLC systems.
Its working principle includes:
- Storing PLC program logic in EEPROM memory cells
- Retaining data even when system power is removed
- Allowing read/write operations for program updates
- Serving as backup memory for CPU RAM-based programs
- Enabling duplication of control logic across multiple systems
Once a program is developed in PLC RAM, it can be transferred into these EEPROM chips for permanent storage and system recovery purposes.
