Time Switch Guide

The built-in control capability of vfd pushes machine intelligence to the edge. Jeff Payne, AutomationDirect’s product manager, wrote an article for the March 2019 issue of Design World, titled: vfd for integrated PLCs for motion and machine control: programming and setup considerations. Payne explained how AC drives can be controlled by external or internal PLCs, […]

Problem: What is the difference between “off delay” and “true off delay” time delay relays, and when to use the true off delay function? Solution/Resolution: Pneumatic time delay relays work well, but they are usually very large and very expensive. In addition, they only have two functions available: normal open time close (N.O.T.C.) and normal

What is a switch isolator? How does it work? For safety reasons, an isolator can cut off the grid. Isolation is a technical term used to isolate a specific load of equipment. In this article, we will learn more about switch isolator. 1. What is a switch isolator? As mentioned earlier, an isolator or power

Various faults occur during the operation of power grids and machines. Short circuit and overload are the most dangerous faults in the power system. They change the circuit structure, cause changes in power distribution, will bring energy loss, damage the stability of the power system, and affect the normal operation of electrical equipment. Although these

Do you want to know how to replace the circuit breaker? Are you looking for some simple steps to replace the circuit breaker? If so, then you have come to the right place. Replacing the circuit breaker requires several safe and simple steps. In addition, you must also use some tools. The function of the

Introduce A relay is an electronic control device that has a control system (also called an input loop) and a controlled system (also called an output loop). Circuits for automatic control often use this component.In fact, it is an automatic switch that uses a smaller current to control a larger current. As a result, it serves as a circuit regulator, a safety circuit, and a converter. The relay has the characteristics of
