Introduction

Programmable Logic Controllers (PLCs) are essential components in industrial automation systems. They are used to control machinery and processes in various industries. Delta and Mitsubishi are two well-known manufacturers of PLCs, each offering a range of products with different features and capabilities. In this article, we will compare the attributes of Delta PLC and Mitsubishi PLC to help you make an informed decision when choosing a PLC for your automation needs.

Price

One of the key factors to consider when choosing a PLC is the price. Delta PLCs are generally more affordable compared to Mitsubishi PLCs. This makes Delta PLCs a popular choice for small to medium-sized businesses with budget constraints. On the other hand, Mitsubishi PLCs are known for their high quality and reliability, which justifies their higher price tag. If budget is a concern, Delta PLCs may be the better option for you.

Performance

When it comes to performance, both Delta and Mitsubishi PLCs offer excellent speed and accuracy in controlling industrial processes. However, Mitsubishi PLCs are often preferred for applications that require high-speed processing and complex control algorithms. Mitsubishi PLCs are known for their superior performance in demanding industrial environments. Delta PLCs, on the other hand, are suitable for less complex applications where high-speed processing is not a priority.

Programming Software

Another important aspect to consider is the programming software used with the PLCs. Delta PLCs use the Delta Industrial Automation Software (DIAStudio), which is user-friendly and easy to learn. This makes it a great choice for beginners or those with limited programming experience. On the other hand, Mitsubishi PLCs use the GX Works3 software, which is more advanced and offers a wide range of programming options. If you require advanced programming capabilities, Mitsubishi PLCs may be the better choice for you.

Communication Protocols

Communication protocols are crucial for integrating PLCs with other devices and systems in an industrial automation setup. Delta PLCs support a wide range of communication protocols, including Modbus, Ethernet, and CANopen. This makes it easy to connect Delta PLCs with various devices and equipment. Mitsubishi PLCs also offer support for multiple communication protocols, such as CC-Link, Ethernet, and Profibus. Both Delta and Mitsubishi PLCs provide flexibility in communication options, allowing for seamless integration with different systems.

Reliability

Reliability is a critical factor when choosing a PLC for industrial applications. Mitsubishi PLCs are known for their robust design and high reliability, making them a popular choice for mission-critical operations. Mitsubishi PLCs are built to withstand harsh industrial environments and provide uninterrupted operation. Delta PLCs, while reliable, may not offer the same level of durability and longevity as Mitsubishi PLCs. If reliability is a top priority for your automation system, Mitsubishi PLCs may be the better choice.

Support and Service

After-sales support and service are essential considerations when selecting a PLC manufacturer. Mitsubishi has a strong global presence and offers excellent customer support for its PLC products. Mitsubishi provides training programs, technical assistance, and regular software updates to ensure the smooth operation of its PLCs. Delta also offers good customer support, but it may not be as extensive as Mitsubishi's support services. If you value comprehensive support and service, Mitsubishi PLCs may be the preferred option for you.

Conclusion

In conclusion, both Delta and Mitsubishi PLCs have their own strengths and weaknesses. Delta PLCs are more affordable and user-friendly, making them suitable for small to medium-sized businesses with budget constraints. Mitsubishi PLCs, on the other hand, offer superior performance, reliability, and advanced programming capabilities, making them ideal for demanding industrial applications. When choosing between Delta and Mitsubishi PLCs, consider your specific automation requirements, budget, and the level of support and service you need. Ultimately, the best PLC for your application will depend on a combination of these factors.
