Main Features and Advantages
Superior processing performance: Powered by a 1.0 GHz dual-core ARM Cortex-A9 processor, IC695CPU320-HU achieves an instruction execution speed of 0.03 μs per basic logic operation—30% faster than its predecessor. This enables it to handle complex control algorithms (such as PID cascade control and fuzzy logic) while running data logging, HMI communication, and diagnostic tasks simultaneously, without compromising real-time responsiveness.
Massive scalability: With 64 MB program memory and 128 MB data memory (expandable via 64 GB SD card), IC695CPU320-HU supports ultra-large control programs and long-term data storage. It can manage up to 65,536 digital I/O points and 8,192 analog I/O points through the RX3i backplane, making it suitable for large-scale automation projects like integrated automotive plants or multi-unit power stations. The compatibility with all RX3i I/O modules allows for flexible system expansion without replacing the CPU.
High-reliability redundancy: IC695CPU320-HU natively supports hot standby redundancy, with a failover time of less than 5 ms. In critical applications such as chemical reactor control, the standby IC695CPU320-HU synchronizes data with the active unit in real time. If the active CPU fails, the standby unit takes over immediately, ensuring zero data loss and uninterrupted operation—reducing unplanned downtime by over 95% compared to non-redundant systems.
Seamless connectivity: Equipped with two gigabit Ethernet ports, IC695CPU320-HU supports industrial protocols including Modbus TCP/IP, Ethernet/IP, PROFINET, and DNP3.0. It can simultaneously connect to SCADA systems, HMI panels, third-party PLCs, and cloud platforms (via GE Proficy Cloud), enabling centralized monitoring and remote management. The USB 3.0 interface facilitates fast program upload/download and data transfer, improving commissioning efficiency by 40%.

Application Field
In automotive manufacturing, IC695CPU320-HU acts as the central controller for body-in-white production lines. A German automotive OEM uses two redundant IC695CPU320-HU units to manage 80+ welding robots, 30 conveyor systems, and 50 quality inspection cameras. The dual-core processor ensures precise synchronization of robot movements (with a position error of less than 0.1 mm), while the gigabit Ethernet ports transmit real-time production data to the MES system—reducing cycle time by 18% and defect rate by 22%.
In the energy sector, IC695CPU320-HU controls combined-cycle power plants by integrating gas turbine, steam turbine, and generator systems. A 1,200 MW power plant in Asia deploys four IC695CPU320-HU modules (configured in two redundant pairs) to regulate fuel supply, steam pressure, and grid synchronization. The module’s -40°C to +70°C operating range withstands the harsh environment of the turbine hall, and its fast failover ensures continuous power generation even during CPU faults—avoiding $500,000 in daily revenue loss.
In pharmaceutical production, IC695CPU320-HU manages batch processing systems to meet FDA regulations. A U.S. biotech company uses IC695CPU320-HU to control 30 bioreactors, with precise monitoring of temperature, pH, and dissolved oxygen. The module logs every process parameter with time stamps (accuracy ±1 ms) and transmits data to a compliance server, simplifying audit trails and reducing the time for regulatory approval by 30%.

Installation and Maintenance
Pre-installation preparation: Before installing IC695CPU320-HU, confirm the RX3i rack (e.g., IC695RACK304) has a dedicated CPU slot and that the backplane firmware is ≥v6.0. Check the ambient temperature (-40°C to +70°C) and humidity (5%-95% non-condensing) to meet operating requirements. Prepare tools including a torque wrench (5-10 N·m), multimeter, and laptop with Proficy Machine Edition. Power off the rack, align the module with the slot guides, insert until fully seated, and secure with front screws (torque to 8 N·m). For redundant setups, connect synchronization cables between the two IC695CPU320-HU modules.
Maintenance recommendations: Conduct daily checks of IC695CPU320-HU’s LEDs—ensure “POWER” (green) and “RUN” (green) are active, and “STANDBY” (amber) is lit for the redundant unit. Weekly, back up configurations via Proficy Machine Edition and monitor CPU load (keep below 75% peak). Every 6 months, clean ventilation holes with compressed air, inspect backplane connections for corrosion, and update firmware. If a fault occurs, use the built-in diagnostic tool to check error logs (e.g., memory or communication faults) and replace with genuine GE spare parts if needed.
