The difference between electronic and mechanical interlocks for pass box
The difference between electronic and mechanical interlocks for pass boxWindow interlocks can effectively reduce the airflow between the cleanroom and the outside airflow. Types of window interlocks include electronic interlocks and mechanical interlocks.1. Pass box electronic interlock Mainly based on electric locks, door magnets, relays, transformers, and other electrical accessories and components to achieve the Simply put, the mechanism of electrical interlocking is by connecting the normally closed contacts of two relays to the coil control circuit of another relay, so that in this case, the electrical action of one relay, the other relay coil can not form a closed circuit. Electrical interlock is mainly set up to ensure the safe operation of electrical appliances, which is controlled by two electrical components to form an interlock with each other. 2. Mechanical interlocking of the transmission window Mechanical interlocking is to achieve interlocking through mechanical parts, such as two switches can not be closed at the same time, You can use mechanical leverage so that when a switch is closed, the other switch is mechanically stuck and can not be closed. Electrical interlocking is easier to achieve, flexible, and simple, interlocking two devices can be installed in different locations, but less reliable. Mechanical interlock is highly reliable, but more complex, sometimes even impossible to achieve. Now on the market transfer window to electronic interlocking for more, mechanical interlocking transfer window accounted for a negligible proportion, which is mainly because the electronic interlocking transfer window is easy to operate and can meet the basic functions of the cleanroom transfer window, after the market test, is the cleanroom transfer window interlocking form applicable. |
