Description
Overview
The IC693ACC302B backup battery is a GE PACSystems accessory designed to preserve volatile memory in legacy Series 90‑30 PLC CPUs. It provides temporary power to retain user logic, configuration data, and system parameters during power loss events. Although an older design, it remains essential for maintaining data integrity in long‑running installations that still rely on Series 90‑30 hardware.
Functional Characteristics
This module uses a compact coin‑cell battery assembly to supply standby power to the CPU’s RAM. The IC693ACC302B was engineered for straightforward installation and direct compatibility with 90‑30 controllers, requiring no firmware changes or auxiliary hardware.
Backup duration varies depending on CPU model and environmental conditions, but the battery is intended for short‑term retention rather than extended outages. Its simple construction and predictable behavior made it a standard component in earlier GE automation systems.
GE later introduced the IC695ACC302 smart battery for PACSystems CPUs, offering improved diagnostics, longer retention time, and low‑battery monitoring—capabilities not present in the IC693ACC302B. However, the original module remains fully functional for legacy applications.
Mechanical and Electrical Design
The battery module is compact, measuring 5 × 1.3 × 4.4 cm and weighing only 0.04 kg. It is designed for quick replacement and includes a keyed connector to prevent incorrect installation. Its lightweight construction allows it to fit easily within Series 90‑30 CPU housings.
System Integration
The IC693ACC302B is compatible exclusively with GE Fanuc Series 90‑30 PLCs and does not support newer PACSystems controllers. It provides RAM retention for CPUs that rely on volatile memory for program storage. No configuration is required—installation is plug‑and‑play.
