Product Features

The influence of current ratio on relay reliability: The so-called current ratio is the ratio of the working load current of the relay to the rated load current. The current ratio has a great influence on the reliability of safety control relays, especially when the current ratio is greater than 0.1, the mean time between failures drops rapidly, and when the current ratio is less than 0.1, the mean time between failures is basically unchanged, so it should be used in circuit design The load with a larger rated current can reduce the current ratio, so that the reliability of the relay and even the entire circuit will not be reduced due to the fluctuation of the operating current.

Precautions:

1) In order to maintain the performance of safety control relays, please be careful not to drop safety control relays or subject them to strong impacts. It is recommended not to use the relays that have fallen.

2) Use safety control relays as much as possible in an environment with room temperature and humidity, with little dust and harmful gases. Harmful gases include gases containing sulfur, silicon, and oxidation.

3) For magnetic latching relays, they should be placed in action or reset as needed before use. Pay attention to the polarity and pulse width when applying voltage to the coil.

Function and application:

In the steel industry, whether it is cold rolling, flattening production lines, or uncoiling, cutting, and recoiling of whole steel coils, there is a risk of harm to operators and maintenance personnel. At the same time, unexpected accidents during the production process will also cause serious damage to the machine and equipment, so we invite emergency stop equipment to stop the abnormal operation of the machine to reduce accident losses and the safety of operation and maintenance personnel. The operator and maintenance personnel must be protected by installing safety doors, safety mats, and using emergency stop buttons. Must use safety control relays.

    How the safety light curtain works
    For semi-automatic equipment, safety light curtains are often used, and only semi-automatic equipment will use safety light curtains. The main reason is that semi-automatic equipment requires human intervention.
