Description
GE IC698ACC701 – PACSystems RX7i Auxiliary Battery Module
The IC698ACC701 is a specialized auxiliary battery module designed for the GE Fanuc (now Emerson) PACSystems RX7i controller series. Its primary function is to provide long-term backup power for the CPU’s volatile memory (SRAM), ensuring that critical application data, register values, and internal clocks are preserved during a total power loss. In complex industrial environments, the IC698ACC701 solves the high-stakes problem of data loss during extended outages or maintenance cycles. By offering a significantly higher capacity than standard on-board batteries, this module is essential for systems where downtime must be minimized and where the manual reloading of logic programs or the loss of historical retentive data would be catastrophic to the process.

Key Features & Benefits
- Extended Data Retention: The IC698ACC701 provides superior Amp-hour capacity compared to standard batteries, protecting memory for extended periods during shelf storage or prolonged power-off states.
- Seamless Installation: Equipped with a pre-terminated wire lead and connector, it allows for a “plug-and-play” replacement process that does not require soldering or complex tools.
- Enhanced System Reliability: By securing the retentive memory of RX7i CPUs, it ensures that the PLC can perform a “hot start” immediately upon power restoration, maintaining process continuity.
- Low-Power Warning Integration: When connected, the IC698ACC701 allows the CPU to monitor voltage levels and trigger a “Battery Low” LED or software alarm, giving operators ample time for scheduled maintenance.
Application Scenarios
- Critical Infrastructure: Deployed in water treatment plants and power distribution hubs where the loss of configuration data or setpoints during a power failure could lead to system-wide instability.
- Continuous Manufacturing: Used in automotive assembly lines where the IC698ACC701 ensures that the CPU retains its exact state and step-logic position during weekend shutdowns or emergency power-offs.
- Remote Terminal Units (RTUs): Ideal for remote oil and gas installations where technicians may not be immediately available to reload software following a localized power disruption.
Frequently Asked Questions (FAQ)
- Q: What is the primary function of the IC698ACC701?
- A: It is an auxiliary battery pack used to maintain the CMOS RAM (program and data memory) and the Real-Time Clock in GE PACSystems RX7i CPUs during power outages.
- Q: Is IC698ACC701 compatible with legacy systems?
- A: The IC698ACC701 is specifically designed for the PACSystems RX7i VME-based architecture. It is not compatible with the smaller RX3i or Series 90-30 systems, which use different battery form factors.
- Q: Can I replace the battery while the PLC is running?
- A: Yes, it is recommended to replace the IC698ACC701 while the power is ON to ensure the CPU memory is powered by the power supply during the swap, preventing data loss.
