Specification

Description

The 489-7907 (4897907) C7.1 ECU Controller is a core control unit customized for CAT 320GC excavators. As the "intelligent brain" of the excavator, it is developed based on the C7.1 engine system architecture and deeply matches the equipment's power output, hydraulic control, and operation logic. This controller integrates a high-precision data acquisition module, multi-channel control interface, and anti-interference signal processing unit. It can real-time receive key operating parameters such as engine speed, hydraulic system pressure, and fuel injection status, and output precise control commands through preset optimization algorithms, ensuring the excavator operates stably under various working conditions such as excavation, crushing, and hoisting. Its appearance and structure strictly comply with Cat's original factory standards, and the installation interface and pin definition are completely consistent with the original parts, which can directly replace the faulty unit without additional modification to the equipment lines or control programs, greatly reducing maintenance and replacement costs and downtime.

Advantage

• Original Factory Compatibility:Developed and produced in full compliance with the technical specifications of CAT 320GC excavators and C7.1 engines, with pin definitions and communication protocols completely consistent with the original ECU. It can be directly installed and used without modifying the equipment program, avoiding control disorders caused by compatibility issues.
• Precise Control & Energy Efficiency Optimization:Equipped with a high-performance microprocessor and advanced control algorithms, it can dynamically adjust fuel injection volume, air intake volume, and hydraulic system pressure in real-time, keeping the engine operating in the optimal working range. While improving work efficiency, it effectively reduces fuel consumption, and the measured fuel saving effect can reach 5%-8%.
• Strong Anti-Interference & High Stability:Adopting military-grade anti-electromagnetic interference components and a sealed dust-proof structure design, it can effectively resist electromagnetic radiation, vibration impact, dust, and oil pollution common in excavator working environments. The working temperature range is -40℃ to 85℃, and it can still maintain stable control performance under extreme working conditions. The Mean Time Between Failures (MTBF) exceeds 10,000 hours.
• Convenient Diagnosis & Easy Maintenance:Supports full-function diagnosis of Cat's dedicated diagnostic equipment (such as CAT ET), which can quickly read fault codes, real-time data streams, and historical operation records, helping maintenance personnel accurately locate the cause of faults and shorten maintenance time. It also has a self-protection function. When abnormal working conditions are detected, it will automatically trigger an emergency protection mechanism to avoid damage to the engine and related components.

Performance

• Data Processing Performance:Adopting a 32-bit high-performance microprocessor with a main frequency of up to 1GHz and a data processing speed of 1000MIPS, it can process more than 20 real-time sensor signals at the same time, and the command response time is ≤10ms, ensuring quick feedback to the instantaneous control needs of the engine and hydraulic system.
• Control Precision Parameters:Fuel injection control precision ±0.01mm³/stroke, engine speed control precision ±5rpm, hydraulic pump displacement control precision ±2%, which can effectively ensure the smoothness of actions and the consistency of power output during operation.
• Communication Capability:Supports CAN 2.0B industrial bus communication protocol, with a maximum communication rate of 500kbps, which can realize high-speed data interaction with excavator instruments, hydraulic controllers, sensors and other components, avoiding control lag caused by communication delay.
• Power Supply & Storage Performance:Adapts to a wide voltage input range (10V-32V), with overvoltage, undervoltage, and overcurrent protection functions; built-in 8MB Flash memory chip, which can permanently store fault codes, operating data, and control programs, and data will not be lost after power failure, facilitating subsequent fault tracing and analysis.
• Environmental Adaptability:The protection level reaches IP67, which can effectively prevent rainwater and dust from entering; it has the ability to start at -40℃ low temperature and run stably at 85℃ high temperature, and can resist vibration and impact of 10-2000Hz, adapting to harsh working environments such as mines and construction sites.
