GE PACSystems RX3i IC695CBL002 1-Meter Energy Pack CPU Connection Cable

Product Overview

The IC695CBL002 is a specialized interconnect cable engineered for the GE Fanuc (Emerson) PACSystems RX3i platform. Its primary function is to establish a secure, low-impedance connection between an RX3i CPU (such as the IC695CPE305 or CPE310) and its corresponding Energy Pack (e.g., IC695ACC400). This cable ensures that the CPU retains critical volatile memory during power loss by facilitating the necessary backup power transfer and signaling.

Detailed Engineering Specifications

Designed for the high-performance RX3i backplane environment, the IC695CBL002 features integrated termination to maintain signal integrity over its length.

Installation and Maintenance Notes

The IC695CBL002 utilizes a keyed 7-pin connector to prevent improper orientation during installation in high-density PLC racks. Given its role in memory protection, it is vital to ensure the connectors are fully seated and the thumb screws (if applicable) are tightened. While the original data suggests "Analog" I/O type, this cable is functionally a dedicated DC power and signaling bus for the RX3i capacitor-based energy storage units.

Why the IC695CBL002 is Critical

In modern RX3i architectures, the Energy Pack replaces traditional lithium batteries. The IC695CBL002 is the vital link that allows the CPU to perform an "orderly shutdown" by writing RAM data to non-volatile flash memory the moment a power failure is detected. Without a functional cable, the CPU cannot access the stored charge of the Energy Pack, leading to potential data loss.

Technical FAQ

Is the IC695CBL002 compatible with older Series 90-30 CPUs?

No. This cable is specifically designed for the PACSystems RX3i "Advanced" CPU line and Energy Pack peripherals. Series 90-30 systems typically use standard lithium batteries located behind the CPU faceplate.

Can this cable be extended beyond 1 meter?

GE Fanuc specifies the IC695CBL002 at 1 meter to ensure proper voltage levels and signal timing. Extending this cable with third-party adapters is not recommended as it may interfere with the CPU's ability to trigger a memory backup during a power sag.

Does this cable require a separate termination plug?

No, the termination resistor is built directly into the cable assembly to simplify installation and reduce the number of discrete components in the system.
