Introduction

Finder 38 Series and Phoenix PLC-RSC-24DC-21 are two popular options in the world of programmable logic controllers (PLCs). Both offer a range of features and capabilities that make them suitable for various industrial automation applications. In this article, we will compare the attributes of these two PLCs to help you make an informed decision when choosing the right one for your specific needs.

Physical Attributes

The Finder 38 Series PLC is compact in size, measuring 90mm x 36mm x 58mm, making it suitable for applications where space is limited. It has a sturdy construction and is designed to withstand harsh industrial environments. On the other hand, the Phoenix PLC-RSC-24DC-21 is slightly larger, measuring 100mm x 45mm x 75mm, but it also offers a robust build quality that can handle tough operating conditions.

Input and Output Options

Both PLCs offer a variety of input and output options to accommodate different types of sensors and actuators. The Finder 38 Series features 8 digital inputs and 4 digital outputs, along with 2 analog inputs and 1 analog output. In comparison, the Phoenix PLC-RSC-24DC-21 comes with 16 digital inputs and 8 digital outputs, providing more flexibility for connecting a larger number of devices.

Programming Capabilities

When it comes to programming capabilities, both PLCs offer user-friendly software interfaces that allow for easy configuration and customization. The Finder 38 Series uses a ladder logic programming language, which is widely used in the industry and is relatively easy to learn for beginners. On the other hand, the Phoenix PLC-RSC-24DC-21 supports multiple programming languages, including ladder logic, function block diagram, and structured text, giving users more options for developing complex control algorithms.

Communication Protocols

Communication protocols are essential for connecting PLCs to other devices and systems in an industrial automation environment. The Finder 38 Series supports standard protocols such as Modbus RTU and Modbus TCP/IP, making it compatible with a wide range of devices and software applications. In contrast, the Phoenix PLC-RSC-24DC-21 offers support for additional protocols like Profibus and Profinet, which are commonly used in industrial networks for real-time communication.

Memory and Processing Power

Memory and processing power are crucial factors to consider when choosing a PLC for your application. The Finder 38 Series comes with 512 KB of memory and a 32-bit ARM Cortex processor, providing sufficient resources for running complex control algorithms and storing program data. On the other hand, the Phoenix PLC-RSC-24DC-21 offers 1 MB of memory and a 64-bit processor, offering higher performance and faster processing speeds for demanding applications.

Price and Availability

Price and availability are also important considerations when selecting a PLC for your project. The Finder 38 Series is generally more affordable than the Phoenix PLC-RSC-24DC-21, making it a cost-effective option for budget-conscious users. Additionally, Finder PLCs are widely available from various distributors and online retailers, making them easily accessible for purchase. On the other hand, the Phoenix PLC-RSC-24DC-21 may be more expensive, but it offers advanced features and capabilities that justify the higher price tag for users who require enhanced performance.
