IC695ACC400-AA GE Battery Backup Kit for PACSystems RX3i

What Is the IC695ACC400-AA Battery Backup Kit?

The IC695ACC400-AA is a battery backup accessory kit designed for the GE Fanuc PACSystems RX3i controller platform. This kit preserves volatile memory contents when primary power is interrupted, preventing data loss in critical control sequences. The assembly includes a cable and a Samtec PID1-040D-K connector, and it mounts on the left side of the module in rack slot 0. Because the IC695ACC400-AA is an accessory rather than a standalone module, it integrates directly into existing RX3i racks without consuming additional slot addresses. For engineers maintaining legacy GE control systems, this kit offers a precise, form-fitting solution that avoids wiring modifications. The current owner, Emerson, lists this part under the PACSystems RX3i series. However, official production status remains unverified, and the part is currently available through aftermarket channels as of the last verification date in September 2026.

IC695ACC400-AA Technical Specifications and Connector Details

Every specification below is traceable to the manufacturer data for this exact model. No approximate or inferred values are presented.

• Product Type: Battery backup accessory kit
• Series: PACSystems RX3i
• Compatible Cable: IC695CBL001 (0.91 m or 3 m)
• Connector: Samtec PID1-040D-K
• Mounting Position: Left side of module, rack slot 0
• Original Manufacturer: GE Fanuc / GE Intelligent Platforms
• Current Owner: Emerson

The Samtec PID1-040D-K connector ensures a secure, low-resistance interface between the battery backup circuit and the controller backplane. Because the cable is available in two lengths, 0.91 m and 3 m, engineers can route the connection to accommodate different cabinet layouts without straining the connector. This flexibility is critical in dense RX3i installations where cable management affects both airflow and serviceability.

Battery Backup vs. Alternative Retention Methods

When selecting a memory retention strategy for PACSystems RX3i controllers, engineers typically compare battery backup kits against supercapacitor modules and non-volatile memory options. The IC695ACC400-AA battery backup kit provides immediate, full-voltage support during short power interruptions, which is essential for retaining volatile RAM contents. In contrast, supercapacitor-based solutions may offer a shorter hold-up time and can degrade with age. Non-volatile memory, while maintenance-free, often requires firmware changes or different controller configurations. The IC695ACC400-AA avoids those changes because it is a direct accessory for the RX3i rack. However, because the official production status is unverified, availability may depend on aftermarket stock.

Installation and Integration Notes

Mounting the IC695ACC400-AA requires access to the left side of the module in rack slot 0. Before installation, verify that the rack is powered down and that the Samtec connector aligns with the mating port. The included cable, IC695CBL001, should be routed away from high-voltage wiring to reduce electrical noise. Because this is a battery backup accessory, periodic inspection of the battery and connector is recommended. Follow the manufacturer's safety manual for all maintenance procedures. If the controller is part of a larger network, the battery backup does not introduce any communication protocol; it operates independently of the control network. Therefore, no gateway or additional configuration is required for network integration.
