- Functional Features:
- 16-bit industrial microprocessor delivers reliable performance for executing discrete control logic and sequential process control in legacy small to medium-scale automation systems, with sufficient processing speed for non-high-speed manufacturing and process applications.
- 128 KB non-volatile EPROM program memory stores control logic without the need for continuous power, ensuring program integrity during power outages and eliminating the risk of program loss from battery failure.
- 32 KB battery-backed RAM retains process data, variables, and setpoints during power interruptions, with a 5-year battery life reducing maintenance requirements and enabling quick system recovery after power outages.
- Integrated Modbus RTU communication (RS-485) enables seamless integration with legacy HMIs, SCADA systems, and third-party discrete control devices, ensuring compatibility with existing industrial control infrastructure.
- Support for up to 1024 digital and 64 analog I/O points via ALU130 series expansion modules accommodates medium-scale automation applications, such as packaging lines, material handling systems, and small batch process control systems.
- Ladder Logic programming (Modicon Concept legacy software) provides a familiar programming environment for maintenance engineers trained on legacy Modicon systems, reducing training time and simplifying system modification and troubleshooting.
- RS-232 direct programming port enables easy connection to a PC for program upload/download and on-site troubleshooting, with no additional communication modules required for basic programming tasks.
- Built-in real-time diagnostics and LED status indicators provide instant visual feedback on CPU, memory, communication, and I/O status, enabling quick fault identification and troubleshooting in industrial environments.
- Rugged industrial design with wide temperature tolerance (0°C to +60°C) ensures reliable performance in unconditioned industrial control cabinets and light industrial manufacturing environments, excluding extreme cold/hot conditions.
- Seamless integration with Modicon ALU130 series I/O modules enables plug-and-play system expansion, with no complex configuration required for basic I/O communication, simplifying system retrofitting and expansion.
- Compact design saves space in legacy control panels, enabling direct replacement of faulty ALU130 CPU modules without modifying the control panel enclosure or wiring.
- Application Scenarios:
- Legacy manufacturing line retrofitting for controlling packaging machines, assembly stations, and material handling conveyors in automotive, electronics, and consumer goods manufacturing plants, extending the service life of existing automation systems without full replacement.
- Small-scale batch process control for chemical, food, and beverage production facilities, with control of mixers, pumps, and valves in small batch reactors and processing lines where high-speed control is not required.
- Water and wastewater treatment for controlling small pump stations, lift stations, and simple treatment processes in municipal infrastructure, with Modbus communication for remote monitoring via legacy SCADA systems.
- Building automation for controlling HVAC, lighting, and access control systems in older commercial and industrial buildings, maintaining compatibility with existing legacy building control infrastructure.
- Light industrial equipment control for custom manufacturing machinery, such as specialized labeling machines and small material handling systems, where replacing the CPU would be cost-prohibitive and legacy I/O modules are still functional.
- Municipal infrastructure for controlling street lighting, traffic signal systems, and small water supply pumps, with rugged design for outdoor and semi-outdoor installations in municipal electrical systems.
- Mining and mineral processing for controlling small conveyor systems and material handling equipment in remote mine sites, with Modbus communication for local monitoring and control in harsh mine site environments.
