Electrical Interlock Circuit Diagram

Some contactors come equipped with the option of a mechanical interlock.

A lever joining the armatures of two contactors together so that they are physically prevented from simultaneous closure.

Lots of circuits similar to this interlocking circuit are used in industries. Three phase motor power control diagrams. This will allow the normally open contacts of ca to close where we have used on for the retaining circuit in parallel with the start a and the other as the interlock contact in the circuit of motor b with the contact now closed should you push the start button of motor b the power will flow through to the coil and energize it. Motor control forward reverse.

An interlock is a feature that makes the state of two mechanisms or functions mutually dependent. Below is a simple electrical circuit. For additional safety electrical interlocks may still be used and due to the simplicity of the circuit there is no good reason not to employ them in addition to mechanical interlocks. Now in case of plc i will explain you by an example.

This is a simple electrical interlocking circuit. It may be used to prevent undesired states in a finite state machine and may consist of any electrical electronic or mechanical devices or systems. The circuit interlocking depends on the nature of working and task which is to be done by motors. It may be used to prevent undesired states in a finite state machine and may consist of any electrical electronic or mechanical devices or systems in most applications an interlock is used to help prevent a machine from harming its operator or damaging itself by preventing one element from.

Collection of interlock wiring diagram. You can tell by the symbols that this single line diagram has three resistors and a battery. Modification in the electrical interlocking control circuit. Electrical connections boundary seal to be in accordance with article.

A wiring diagram is a streamlined conventional photographic representation of an electric circuit. It reveals the elements of the circuit as streamlined shapes as well as the power and signal connections in between the tools.
