A1SJCPU Redundant Power Supply Module Mitsubishi Universal model
The A1SJCPU is a compact, high-performance PLC CPU unit designed for small to medium-scale automation applications. It serves as the central processing unit for the Mitsubishi A Series PLC system, handling program execution, logic operations, data processing, and communication with various I/O and special function modules. It features a program memory capacity of 8K steps and can support a maximum of 256 I/O points
. Its design emphasizes reliability and ease of integration into diverse industrial control systems.
Efficient Processing: The CPU utilizes Mitsubishi's proprietary sequential control chip (MSP), offering processing speeds and instruction sets that were competitive with larger PLCs at its time
.
Modular System Expansion: The A1SJCPU works within a modular PLC structure, allowing users to expand the system's capabilities by adding various I/O modules (digital, analog), special function modules (positioning, temperature control, high-speed counting, network communication), and extension base units to meet specific application needs
.
Stable Program Execution: It operates on a cyclic scan process, consistently executing user programs through stages of input sampling, program execution, and output refresh, ensuring predictable and reliable control behavior
.
Programming Flexibility: The unit supports standard PLC programming languages, notably ladder logic, for creating control programs. It is programmable using Mitsubishi's software tools like GX Developer
.
Integrated Functionality: Some variants may include built-in features like a data communication line interface (e.g., coaxial or optical data link), enhancing its connectivity options for network configurations like MELSECNET
.
Material/Construction: As an electronic industrial control component, the A1SJCPU is housed in a durable casing designed to withstand typical industrial environments, including resistance to vibration, electrical noise, and varying temperatures. The internal circuitry is built on printed circuit boards (PCBs) with integrated circuits and connectors.
Primary Uses: This CPU unit was commonly applied in a wide range of automation tasks, such as controlling industrial machinery, assembly lines, packaging equipment, and material handling systems. It is suited for applications requiring sequential control, timing, counting, and basic data manipulation.
