HC-RP503 MITSUBISHI

HC-RP503 MITSUBISHI central processing unit

Product  Description：

Mitsubishi Electric offers a diverse range of Central Processing Units (CPUs) under the MELSEC brand, designed to serve as the "brain" of a Programmable Logic Controller (PLC) system. These CPUs range from the flagship MELSEC iQ-R series for large-scale, high-speed applications to the compact MELSEC iQ-F series for smaller, cost-effective automation.

Product Details and Parameters

The core technical parameters of Mitsubishi CPUs are defined by their processing speed, memory capacity, and connectivity options. In the flagship iQ-R series, the LD (Load) instruction processing speed can reach as fast as 0.98 nanoseconds, enabling exceptionally short system scan times. Program capacity varies significantly to match system complexity, with high-end models supporting up to 1200K steps.

Memory management is robust, often featuring built-in SD memory card slots for data logging, backup, and restore functions. Most modern Mitsubishi CPUs include integrated Ethernet and USB ports for direct engineering tool connection and network communication. Advanced models also feature multi-CPU support, allowing up to four CPUs (such as a sequence CPU, a motion CPU, and a safety CPU) to reside on a single base unit, sharing data via a high-speed system bus.

Key Product Advantages

Mitsubishi CPUs are recognized globally for their high performance and reliability. One of the primary advantages is the ultra-high-speed processing capability, which reduces cycle times and improves machine productivity. The "iQ Platform" concept allows for seamless integration of different control types—sequence, motion, safety, and C-language—within a single environment, reducing hardware footprint and integration complexity.

Scalability is another major benefit. Users can start with a basic CPU and upgrade as system demands grow without changing the underlying architecture. Furthermore, the GX Works3 engineering software provides an intuitive, graphical environment that simplifies programming and troubleshooting. Mitsubishi also emphasizes long-term maintenance and backward compatibility, ensuring that newer CPUs can often replace older models with minimal adjustment.

Product Applications

Mitsubishi CPUs are utilized across nearly every sector of industrial automation. In the automotive industry, they manage complex assembly lines and robotic synchronization. In the semiconductor and electronics sectors, their high-speed processing is vital for precision positioning and rapid throughput.

They are also widely applied in food and beverage packaging, where high reliability and hygiene-compliant control are required. For public infrastructure, Mitsubishi process-control CPUs are used in water treatment plants and energy management systems due to their redundant capabilities and high availability.

Essential Precautions

To ensure the safety and longevity of the CPU, several precautions must be strictly followed during installation and operation. All power phases must be disconnected externally before attempting any wiring work to prevent electric shock or hardware damage. The CPU should be installed in an environment free from excessive dust, oily smoke, corrosive gases, and heavy vibration.

Care must be taken during wiring to keep communication and control cables at least 100mm away from high-voltage power lines to avoid malfunction caused by electromagnetic noise. It is also critical to never touch the conductive parts or electronic components directly, as static electricity can damage the sensitive internal circuitry. Finally, users should always configure external safety circuits, such as emergency stops and protective interlocks, to ensure the system remains safe even if the CPU detects an error and shuts down outputs.
