Product Introduction

REX521GHHGSH51G 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.

Ensuring the safety and reliability of installed products is not a temporary matter, but the top priority of ABB”s
more than 100 years of R&D and technological innovation. To this day, ABB”s rich and diverse installation
product series also have their own “safety secrets”.

For example, in order for a seemingly inconspicuous small cable tie to work in various extreme environments
and still provide normal performance without brittleness even if it is deployed in a wind power station at minus
40 degrees Celsius, not only ABB cable ties are needed The careful selection of materials also benefits from
maintaining full inspection during the manufacturing process.
Even 1-2 holes of cable ties are selected for each mold for destructive testing to ensure its reliability.

“If the product cannot be found to have failures or defects during production and quality inspection,
it is equivalent to passing on the manufacturing costs borne by the manufacturer to the user. If the
manufacturer only needs 5 cents to improve each defect found, then the user is deploying If a defect is
discovered later, it will cost more than 100 times to repair and replace.”
Dong Gang used a set of price comparisons to vividly express why the cost value of installed products
must ensure safety and reliability.

For lightning protection grounding applications, the lightning protection grounding system and
surge protection system solutions provided by ABB can comprehensively protect the safe,
reliable and long-lasting operation of building power supply and distribution equipment. Among them, the
copper-plated conductors adopt four-dimensional continuous plating method, which can be The thickness of the electroplating layer is
greater than 0.25 mm, with good electrical conductivity and stable electrical performance.

For electrical connection products, ABB provides customers with process standardization ideas and
reliable solutions from multiple dimensions such as manufacturing, experimental testing, and factory
inspection. For example, ABB terminals and cold-pressed connector products use T1 copper as the
raw material, and the copper content It is 99.99%.
The surface of the terminal adopts tin plating process, and the thickness of the coating reaches 7μm,
which provides the terminal with better corrosion resistance. At the same time, the product has
passed the test standards of IEC60352 and IEC61238-1-Class B and meets the CE certification. The
relevant test standards will also conduct more stringent tests
in terms of temperature rise of the terminal and pull-out force requirements after crimping. Not only that,
ABB uses color codes on terminal products, which
are used in conjunction with the color codes on the crimping molds to standardize crimping from a
process perspective and prevent installers from using wrong tools, causing the terminals to fail to reach the rated pulling force.
