Process technology refers to the quality of electrical contact points in an electrical system, and reliability is the most important aspect for the overall system. How would you define reliability in an electrical system? Some might say that the system is in the PLC (Programmable Logic Controller), the DCS (Distributed Control System), or units. However, it is possible to measure the reliability of electric systems to the point where the wires meet. For the average person, this is alsoknown as an electrical connection. From an industrial point of view this application are referred to as terminals.
Factors that affect an electrical system
There are many things that relate to an electrical system, but conditions such as extreme heat and cold have the greatest influence. Other things to consider flammability, and this is particularly important in the petrochemical and food industries. In North America, 100 ATEX (94/9/EC) was appliedprotection systems and equipment in hazardous environments. National Electrical Code and Canadian Electrical Code are used in these environments.
Programmable Logic Controller
The following are the most important requirements for terminals:
It must be ensured and should never come to the end point of losing. They have an elastic component when originally meant for the multi-manager The insulating parts can meet the pressure point.
These requirements mustbe tested by third party testing center and must be certified with a certificate of approval.
In process engineering, you should be aware of the constant changes in temperature. This test confirmed that the endpoints of a consistently high quality at constant even when the temperature changes. Terminals, carriers are clamping fastened and connected to a conductor for the test. The test method is a double room, the examination of terminal blocksTemperatures near their upper and lower limit. These limits range from -50 ° C to over 105 ° C. They are usually tested at this temperature for an hour and the temperature can change several times within one minute. This process continues a few dozen times, and if the parties are not damaged after the test requirements have been met.
Voltage drop test for terminals
To maintain a strong electrical bond, their points of contactshould be free of corrosion. The voltage drop test is known as a test of corrosion protection, and the terminals must pass a test, where they bear the sulfuric acid. The terminal blocks are exposed to sulfuric acid for several hours and then try again. Following are manually to ensure that the contact point, which is strongly controlled.
It may sound simple, but each of them to follow these stringent tests for quality and stability. In other words, if yourTerminal fails the whole system fails and delayed production. From the business point of view, this is unacceptable and can cost tens of thousands of dollars. So the lesson here is to make sure that you will do your research and quality for your business.
