Features:

  • Interface Between the IC693ACC302 Auxiliary Battery Module and Series 90‑30 CPU Backplane
  • Combines Capability of Reliable Memory Backup with Long-Term Data Retention
  • Operates in Conjunction with Series 90‑30 CPU Modules and Compatible PLC I/O Systems
The IC693ACC302 operates as an auxiliary battery module for the Series 90‑30 PLC system, providing reliable backup power to preserve CPU memory, configuration data, and retentive variables during primary power interruptions. It continuously supplies a regulated 3.6 V DC output to the CPU memory circuits, ensuring that program and data integrity are maintained under normal and abnormal power conditions. The IC693ACC302 is designed for industrial environments and supports seamless integration with Series 90‑30 CPUs; multiple modules can be used in parallel or in redundant configurations to enhance memory retention reliability.

The IC693ACC302 provides essential memory backup functions for the Series 90‑30 PLC system, and is a critical component of CPU operation, directly affecting the retention of user programs, configuration data, and retentive memory during power interruptions. One or more IC693ACC302 modules may be installed per CPU depending on the required backup duration and system configuration. The IC693ACC302 mounts directly to the Series 90‑30 CPU backplane or designated battery slot and ensures reliable power supply for all associated memory circuits.

For critical memory backup applications, multiple IC693ACC302 modules can be deployed in parallel to support redundant CPU retention configurations within the Series 90‑30 PLC system. In addition to standard single-module operation, the redundant setup performs automatic monitoring and switchover. The CPU continuously monitors the integrity and voltage level of each battery module. If the system detects that a primary IC693ACC302 is no longer providing stable backup power (outside configured voltage or retention thresholds), it automatically switches to the secondary module as the active memory backup source and logs an event in the System Event List.

The IC693ACC302 Auxiliary Battery Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Description
The Auxiliary Battery Module is a component designed to extend the memory backup time for various GE control systems, including the Series 90-30, Series 90-70, and PACSystems CPUs. This auxiliary battery replaces the standard CPU RAM backup battery, significantly enhancing the duration for which memory can be retained without external power.

The IC693ACC302 is an auxiliary battery module designed for use with the GE Fanuc Series 90-30 PLC system. It provides extended memory backup capability for CPU modules, preserving user programs, configuration data, and retentive memory in the event of primary power loss.

By supplying stable backup voltage to the CPU memory circuit, the module ensures data integrity and minimizes downtime during unexpected power interruptions.

Installed directly within the Series 90-30 mounting structure, the IC693ACC302 supports long-term memory retention without affecting normal PLC operation. It is commonly applied in industrial automation environments where continuous data preservation is critical, such as power generation systems, manufacturing lines, water treatment facilities, and process control installations.
