Product Details

IC695ACC302-AB Product Description

The GE IC695ACC302-AB is a precision-engineered backup battery module designed for the GE PACSystems RX3i platform — one of the most widely deployed PLC architectures in energy-intensive manufacturing environments. As industrial facilities push toward leaner energy profiles and smarter production scheduling, the role of reliable backup power in the control layer becomes critical. This module ensures that program memory, retentive data registers, and real-time clock values are preserved across power interruptions, preventing costly re-initialisation cycles that waste both time and energy on the production floor.

In modern smart factories, unplanned controller restarts are not merely an inconvenience — they represent measurable energy waste. Each cold-start cycle forces drives, motors, and heating systems to ramp from zero, consuming surge currents that spike energy demand charges. The IC695ACC302-AB eliminates this risk by maintaining the RX3i CPU's memory state, allowing the system to resume from its last known operating point with minimal energy overhead.

The IC695ACC302-AB does not operate in isolation — it is a foundational component within a broader power-aware automation architecture. In a typical RX3i-based control cabinet, the CPU module (such as the IC695CPE302 or IC695CPE310) relies on this battery to retain ladder logic programs, PID loop parameters, and communication configuration data during mains power interruptions. When paired with the IC695PSA040 or IC695PSD040 power supply modules, the system maintains a stable 24 V DC rail that feeds I/O modules, field devices, and communication interfaces without interruption.

On the network side, the RX3i platform commonly integrates IC695ETM001 Ethernet communication modules for PROFINET or EtherNet/IP connectivity, enabling real-time data exchange with SCADA systems and energy management platforms. Preserving the CPU's network configuration across power events — made possible by the IC695ACC302-AB — means that the controller reconnects to upstream systems immediately upon power restoration, avoiding the latency penalties associated with full re-commissioning.

In drive-intensive production lines, the RX3i CPU coordinates with GE AF-650GP or compatible variable frequency drives (VFDs) to regulate motor speed and torque in response to load demand signals. The battery module ensures that the CPU's drive control parameters — including acceleration ramps, deceleration curves, and energy-recovery braking thresholds — remain intact, so drives resume at their optimised operating points rather than defaulting to factory settings that may draw excess current during startup.

For facilities using GE Proficy HMI/SCADA or third-party HMI panels connected via the IC695CMM002 serial communication module, the IC695ACC302-AB preserves the communication address maps and tag databases within the CPU, eliminating the need for manual re-entry of configuration data after a power event. This directly reduces technician intervention time and the associated indirect energy costs of extended downtime.

Power monitoring modules such as the IC695ALG600 analogue input module — when configured for current transformer or voltage transducer inputs — feed real-time energy consumption data into the RX3i CPU. The battery module ensures that the CPU's energy logging registers and alarm thresholds are retained, supporting continuous power quality monitoring without data gaps that could mask inefficiency trends.

Industrial energy optimisation is rarely achieved through a single component upgrade — it is the result of systematic attention to every layer of the control architecture. The IC695ACC302-AB contributes to this goal by eliminating one of the most overlooked sources of energy waste: the uncontrolled restart.

When a PLC loses its program memory due to a depleted or absent backup battery, the restart sequence forces every connected actuator, motor, and heating element to initialise from a default state. Variable frequency drives revert to open-loop control, consuming significantly more current than their tuned, closed-loop counterparts. Servo drives — such as those in the GE Multilin SR750 protection relay ecosystem or compatible servo amplifier platforms — lose their position references, requiring homing cycles that add minutes of non-productive machine time per event. Across a multi-shift operation, these losses accumulate into measurable increases in energy spend and reduced overall equipment effectiveness (OEE).

By maintaining the RX3i CPU's retentive memory, the IC695ACC302-AB enables the following energy and productivity outcomes:

In facilities where the RX3i platform is integrated with GE Proficy Plant Applications or an MES layer, the continuity of CPU data also means that production reporting remains accurate across power events — a requirement for ISO 50001 energy management system compliance and for facilities pursuing carbon reduction targets.

Every IC695ACC302-AB unit supplied by NANKMOS is sourced from verified supply channels, subjected to pre-shipment functional testing, and backed by a 12-Month Warranty. In-stock units are available for immediate dispatch, supporting both planned maintenance schedules and urgent replacement requirements.

Q1: How does replacing the IC695ACC302-AB battery contribute to energy savings on the production line? A depleted battery causes the RX3i CPU to lose its retentive program data on power interruption. The subsequent cold restart forces drives, motors, and process controllers to reinitialise from default parameters, generating surge currents and extended stabilisation periods that consume excess energy. Replacing the IC695ACC302-AB on schedule eliminates this risk, ensuring the controller resumes from its optimised operating state and the production line maintains its energy-efficient rhythm.

Q2: Which GE PACSystems RX3i CPU modules is the IC695ACC302-AB compatible with? The IC695ACC302-AB is compatible with the primary RX3i CPU family, including the IC695CPE302, IC695CPE305, IC695CPE310, and IC695CPE400. If you are operating a different RX3i CPU variant, please contact NANKMOS with your full system configuration for compatibility confirmation before ordering.

Q3: What is the recommended replacement interval, and how is the battery condition monitored? GE recommends replacing the RX3i backup battery every 3 to 5 years under normal operating conditions, though actual service life depends on ambient temperature and CPU power-on time. The RX3i CPU provides a low-battery diagnostic flag accessible via the system status register and visible in Proficy Machine Edition or connected HMI displays. NANKMOS recommends incorporating battery status checks into your scheduled preventive maintenance programme to avoid unplanned data loss events.

Q4: Does NANKMOS provide pre-shipment testing, and what does the 12-Month Warranty cover? Yes. Every IC695ACC302-AB unit dispatched by NANKMOS undergoes functional verification prior to shipment to confirm battery voltage and capacity are within GE specification. The 12-Month Warranty covers manufacturing defects and premature capacity loss under normal operating conditions. Units are held in climate-controlled storage to minimise self-discharge prior to dispatch. For warranty claims or technical support, contact [email protected] or call +86 18359268345.
