Description

GE IC693ACC302A Auxiliary Battery Module

Product Overview

The GE IC693ACC302A is a high-capacity auxiliary battery module designed for GE Fanuc’s Series 90-30 and Series 90-70 PLC systems, providing extended memory backup for critical industrial control applications. As part of the IC693 Series, this module ensures uninterrupted data retention during power outages, safeguarding process parameters, program logic, and diagnostic records in manufacturing, oil & gas, and water treatment facilities.

With a 15 amp-hour (Ah) capacity and 3 V DC output, the GE IC693ACC302A delivers up to 75 months of memory backup for CPUs like the IC693CPU311–364 and IC697CPUs, while supporting 15 months of backup for the IC693CPU374 59. Its galvanic isolation and 1-amp fuse protection shield the PLC’s volatile memory from voltage spikes and short circuits, ensuring data integrity in high-noise environments. Constructed with a flame-retardant ABS plastic housing, the module withstands operating temperatures from 0°C to 60°C and humidity levels up to 95% non-condensing, making it suitable for harsh industrial settings 58.

In automation systems, the IC693ACC302A integrates seamlessly with IC693 power supplies and Genius Bus Interface Units (BIUs), such as the IC693GBI002, to maintain real-time data continuity. Its compact design (145.1 mm × 65 mm × 39.9 mm / 5.7″ × 2.5″ × 1.5″) and lightweight (0.42 kg / 0.93 lbs) facilitate easy panel mounting, while a 24 AWG twisted lead wire with a female 2-pin connector enables quick installation 58. Though discontinued by GE, the GE IC693ACC302A remains essential for legacy systems, offering cost-effective reliability where upgrading to newer platforms is impractical. By combining long-lasting backup power, rugged durability, and flexible compatibility, this module ensures operational continuity in mission-critical industrial processes.

Technical Specifications

Main Features and Advantages

Extended memory backup:
The IC693ACC302A’s 15 Ah capacity provides up to 75 months of memory retention for most Series 90-30 CPUs, significantly longer than standard backup batteries. This ensures critical data—such as process recipes, PID parameters, and alarm logs—remains intact during prolonged power outages, minimizing downtime in applications like chemical batch processing or wastewater treatment. For systems using the IC693CPU374, the module still delivers 15 months of backup, balancing performance with cost 59.

Rugged industrial design:
With a flame-retardant ABS housing and conformal coating, the module resists dust, moisture, and chemical exposure, ensuring reliability in harsh environments like offshore platforms or food processing plants. Its 0°C to 60°C operating range and 95% non-condensing humidity tolerance further enhance durability in extreme conditions 58.

Safety and protection:
The IC693ACC302A incorporates a 1-amp fuse to protect against short circuits and voltage overloads, preventing damage to the PLC’s memory subsystem. Galvanic isolation between the battery and the backplane mitigates electromagnetic interference (EMI) from nearby motors or drives, ensuring stable operation in high-noise settings 59.

Easy integration and maintenance:
The module connects directly to IC693 power supplies and IC697 CPUs via a 24 AWG twisted lead wire, requiring no additional adapters. Its panel-mount design simplifies installation in control cabinets, while a date code on the front panel helps track shelf life and replacement schedules. Regular visual inspections and fuse checks (recommended quarterly) ensure optimal performance 59.

Application Areas

The GE IC693ACC302A excels in industries requiring reliable data retention during power interruptions:

• Manufacturing:
  Safeguards program logic and machine settings in automotive assembly lines, ensuring robotic workcells resume operations seamlessly after power 恢复. Its long backup time is critical for maintaining batch process recipes in pharmaceutical production.
• Oil and Gas:
  Preserves configuration data for wellhead control systems and compressor monitoring units in offshore platforms, where downtime risks environmental hazards or production losses.
• Water and Wastewater Treatment:
  Maintains pump control parameters and valve states in treatment plants, ensuring continuous operation during grid outages. Its moisture-resistant design is ideal for wet, corrosive environments.
• Power Generation:
  Protects turbine control algorithms and generator settings in power plants, minimizing recovery time after blackouts.

Installation and Maintenance

Pre-installation preparations:
Verify compatibility with the target CPU (e.g., IC693CPU364) and power supply (e.g., IC693PWR330). Mount the IC693ACC302A on a clean, grounded panel using four #8-32 flat head machine screws, ensuring the 2-pin connector aligns with the CPU’s battery port. Route the 24 AWG lead wire away from high-voltage cables to minimize EMI. Apply power to the PLC and check the battery status LED for proper operation.

Maintenance suggestions:
Perform quarterly visual inspections to check for loose connections or physical damage. Test the fuse annually using a multimeter to ensure it trips at 1 amp. Replace the module every 7 years (or sooner if the date code indicates expiration) to maintain backup reliability. Store spare IC693ACC302A modules in anti-static packaging at 10–30°C with <60% humidity, testing functionality yearly. Dispose of expired batteries following local regulations and the module’s MSDS guidelines 9.
