Product Introduction

QHMX325 is a high-performance industrial automation communication module that uses high-speed CMOS devices, supports MODBUS protocol, and supports hardware flow control. It is an ideal choice in the field of industrial automation.

As the number of electric vehicles around the world continues to grow, electric vehicle-related concept stocks have been rising. As of the close of trading on the 22nd, the share price of Tesla Inc. (TSLA), the only listed
electric vehicle manufacturer in the United States this year, has soared 156% to $87. Well-known hedge fund Longboard Asset Management issued a report that is “strongly optimistic” about the company, predicting that its
stock price will rise to $100 within 18 months and rise to $200 within five years. Tesla expects to ship a record 20,000 Model S electric vehicles in 2013.

Electric vehicle sales are driving demand for charging solutions that require more complex monitoring systems and software support for the grid . According to the forecast of Parker Research Company in the
United States, the number of electric vehicle charging stations will double in the next few years, and global sales will reach 1.6 million units by 2015. At present, the biggest problem hindering the popularity of electric vehicles
is that charging takes too long. Analysts believe that ABB”s latest fast charging technology is expected to break through this
bottleneck and bring the electric vehicle industry into a new era.

ABB has been committed to finding fast charging solutions for electric vehicles as early as 2011. In July of that year, ABB acquired Netherlands-based Epyon, an early leader in global electric vehicle charging infrastructure solutions,
focusing on DC fast charging stations and networked charging software. The company”s DC fast charging stations, which have been
operational since May 2010, can reduce charging time to 15 minutes, compared with the typical 6 to 8 hours required
using standard AC charging equipment. Epyon”s equipment and software also enable charging stations to monitor charging status and demand, and implement billing and management functions.

Shurig said on the 23rd that ABB plans to promote this technology to global markets including China. ABB is open to the distribution
channels of fast charging piles. It can not only provide products and solutions directly, but also cooperate with local dealers or system integrators.
ABB to provide automation solutions for UK natural gas storage facilities
Zurich – ABB has become the provider of a comprehensive solution based on System 800xA and ABB instrumentation for a new natural
gas storage facility in Cheshire, UK (with a storage capacity of more than 400 million cubic meters).

The Stublach facility, being built for Cheshire-based company Storengy, part of GDF Suez Group, will store natural gas in salt caverns deep underground. The processing plant includes natural gas compressor units that are used to
transport natural gas between the salt caverns and the UK”s National Transmission System (NTS) .

A very important factor why ABB won the bid for this project is that ABB has a complete range of automation , safety and instrumentation products , and System 800xA has been widely and successfully applied around the world.
ABB”s System 800xA control system, together with ABB instrumentation, provides natural asset management capabilities that can help
operators manage and maintain plants more effectively, thereby increasing productivity and reducing energy consumption.

As the main instrumentation and automation contractor (MI AC ), ABB will supply integrated process control and safety instrumented systems
based on System 800xA to Jacobs Engineering, responsible for the plant engineering, procurement and construction (EPC)
, as well as ABB and third parties. Instrumentation . In addition, ABB provides engineering design services for automation and safety instrumented systems (SIS).

The TüV-certified AC 800M HI safety controller and field devices form a safety instrumented system, which is used to control the treatment plant, corresponding pipelines, and the wellhead 2,000 meters away from the treatment plant.

For this reason, ABB configured redundant controllers for the selected 800xA system. The 800xA system also connects to the plant”s fire and gas detection (F&G) and third-party equipment, such as compressors, to monitor the entire plant.
