INDUSTIES | SENTINEL Distributed I/O Modules in the Application on Photovoltaic Monocrystalline Silicon Production Lines

With the global energy structure transforming, the photovoltaic industry, as a crucial part of clean energy, is rapidly developing. China plays an essential role in this transformation, being the largest producer of photovoltaic products worldwide and the forefront of technological innovation and market application. Thanks to its strong manufacturing capability and substantial government support, China's photovoltaic industry is developing in depth, driving global technological progress and the widespread application of photovoltaic technology.

Important Link in the Photovoltaic Industry Chain: Monocrystalline Silicon Production

The photovoltaic industry chain covers a series of complex processes from upstream raw material preparation, midstream cell and module manufacturing, to downstream system integration and application. Among these, the production of monocrystalline silicon is particularly crucial as it directly affects the efficiency and cost of the final photovoltaic products. The production process of monocrystalline silicon includes ingot casting (pulling rods), cutting, squaring, surface grinding, etc., requiring highly precise control systems to ensure product quality. However, the control systems in this process are often large and scattered, posing significant challenges to production efficiency and cost control.

SENTINEL Solutions

Solution 1: EL Series Remote I/O Modules

A domestic photovoltaic component equipment manufacturer adopted the EL series remote I/O modules for the first time in one of its projects. These modules can be installed directly on-site, enabling close signal collection and inter-module connection via Ethernet without the need for traditional control cabinets. This method not only reduces the cost of installation and debugging but also improves the stability of system communication.

Solution 2: CM Series Remote I/O Modules

In another project, considering the need for cost control, the customer requested a more optimal solution. We recommended the CM series remote I/O modules, which, while ensuring stability, cost less than the EL series modules and save on connector costs. However, the installation flexibility is somewhat limited, as they can only be installed within control cabinets. After weighing the pros and cons, the customer accepted this solution.

These two series of products have their respective advantages (for detailed product information, please refer to past articles):
 

• The EL series modules are particularly suitable for applications that require high installation flexibility and streamlined installation processes, thanks to their high field adaptability.

• The CM series modules, on the other hand, are characterized by their cost-effectiveness and the savings on connector costs, meeting the needs of cost-sensitive projects where the application environment allows.
