Recently, Anhui Taihua Instrument Co., LTD., at the invitation of Jiangsu Nantong Ship business under Shanghai Zhenhua Heavy Industry (Group), successfully completed the installation and commissioning of the PLC cabinet signal isolator on site, fully demonstrating the professionalism and reliability of its products.

I. Project background and requirements

With the rapid development of China's shipbuilding industry, the performance requirements for Marine electronic equipment are also increasing. Shanghai Zhenhua Heavy Industry (Group) as a well-known Marine business enterprises, has been committed to the introduction and use of international advanced Marine electronic equipment. This time, they chose the THP-IP411 one-in-four-out, 4-20mA signal isolator produced by Anhui Taihua Instrument Co., Ltd. to be used in the PLC cabinet of its Marine business in Nantong, Jiangsu, to achieve accurate signal isolation and stable transmission.

Second, why choose Anhui Taihua watch

Based on the investigation of our company. This product chooses our THP-IP411 signal isolator, THP-IP411 signal isolator adopts advanced isolation technology, can realize the complete isolation between the input signal and the output signal, effectively prevent the impact of external interference signals on the system. At the same time, the product also supports the design of one in four out, which can isolate and transmit multiple signals at the same time, greatly improving the flexibility and scalability of the system.

In terms of functionality, the THP-IP411 signal isolator can receive standard or non-standard analog signal inputs from the ship's engine site and convert them into standard signal form output to the control room or DCS system. This conversion process not only facilitates the acquisition of ship site data, but also ensures the accuracy and reliability of the signal. In addition, the product supports a standard current signal input of 4-20mA, suitable for the ship's complex types of sensors and transmitters.

In terms of performance, the THP-IP411 signal isolator has the characteristics of high precision, low drift and low noise. In response to the harsh weather environment at sea, it can ensure the stability and reliability of the signal during transmission, thereby improving the performance of the entire system. In addition, the product also has a wide temperature range, high protection level and other characteristics, can work in the harsh industrial environment at sea.

It is worth mentioning that the THP-IP411 signal isolator has passed a number of international and domestic certifications, including China Classification Society CCS, International Electrotechnical Commission (IEC) certification, ATEX certification (Europe) certification, electromagnetic compatibility (EMC) certification, ISO 9001 certification, CE certification, in line with all kinds of Marine electronic equipment application standards.

These certifications prove that the quality and reliability of the product has been widely recognized and trusted. In the field of shipbuilding, this product has been widely used and achieved good results.

3. On-site installation and commissioning

In order to ensure the smooth installation and commissioning of the THP-IP411 signal isolator in the PLC cabinet of the cabin, Anhui Taihua Instrument Co., Ltd. assigned a senior engineering teacher to the site on May 22, 2024 for guidance. With rich engineering experience and professional technical level, Fan Gong conducted a two-day on-site engineering guidance.

Under the careful guidance of Fan, the installation team gradually completed the installation, wiring and debugging of the signal isolator in accordance with the operating procedures. After two days of intensive work, the installation and commissioning of THP-IP411 signal isolator in PLC cabinet was successfully completed. After testing and verification, its performance was stable and reliable, fully meeting the requirements of Marine electronic equipment.

Iv. Project significance and impact

The successful completion of the installation and commissioning of the PLC cabinet signal isolator not only provides high-quality Marine electronic equipment support for the shipbuilding business of Shanghai Zhenhua Heavy Industry (Group) in Nantong, Jiangsu, but also further enhances the influence of Anhui Taihua Instrument Co., Ltd. in the field of shipbuilding, and further proves the excellent quality of our products. It also proves the professionalism of our high-quality talents in the technical application of various field environments. At the same time, the successful implementation of the project also fully proves the reliability of the signal isolator produced by Anhui Taihua Instrument Co., Ltd. in the field of ship manufacturing.

In the future, Anhui Taihua Instrument Co., Ltd. will continue to adhere to the "quality first, customer first" business philosophy, and continue to develop and produce high-quality Marine electronic equipment products, to provide more high-quality technical support and services for domestic and foreign shipbuilding enterprises.
