A solid-state relay is a mechanical relay controlled by a digital signal. This relay doesn’t generate noise but it has a longer lifespan as compared to other mechanic relays. The main benefit of this relay is that it can be easily switched by a low voltage. In addition, this relay can be switched very fast due to no moving contacts for longer periods without wearing out. This article discusses an overview of the g3mb-202p solid state relay or G3MB-202P SSR, its working, and its a … [Read more...]
5V Dual Channel Relay Module : PinOut, Specifications, Interfacing, Working & Its Applications
There are various electrical and electronic components are used in the industrial sector in different applications like resistors, capacitors, transistors, diodes, rectifiers, regulators, relays, amplifiers, transformers, etc. So, relays play a significant role in the electronics industry. Relays are electromagnets that perform like a switch by simply closing or opening their contacts for controlling the flow of current. Relay modules switch ON/OFF electrical devices as well as electronic … [Read more...]
5V Eight Channel Relay Module : PinOut, Specifications, Interfacing & Its Applications
A relay module is a type of electrical switch that operates through an electromagnet where this electromagnet can be activated with a low-power signal from any microcontroller. The main function of this relay module is to switch ON/OFF any electrical device or system and also it serves to separate the control circuit from the system or device being controlled. This module is significant because it allows you to use any microcontroller to control loads with very higher currents & voltages. … [Read more...]
5V 4 Channel Relay Module : PinOut, Specifications, Interfacing & Its Applications
A relay is an electromechanical switch that opens & closes the electrical circuits by getting electrical signals using external sources. These switches include a coil that gets an electric signal & changes it to a mechanical action. The contacts of the relay open and close the electric circuit. Generally, relays operate with AC/DC current, at common voltages & the current they can control ranges from 2A to 30A. A relay module is one type of board where a relay is mounted on this … [Read more...]
What is Mho Relay : Working & Its Applications
In electronic circuits, a relay is a switch that is operated electrically to control the circuit with low power or one signal. First, relays are used as amplifiers in long-distance circuits. The function of the relays is to re-transmit the replicated signal out from one circuit to another circuit. Relays are electromechanical type, solid-state type, and reed type. Similarly, distance relays are one of the types and versatile relays used for distance protection, which depends on the distance … [Read more...]
What is a Distance Relay : Types & Its Characteristics
A distance relay is a fundamental device that trips the circuit breaker in the event of a fault. In low rating power systems circuits, the relay itself can trip the circuit, without the circuit breaker. The relay along with the circuit breaker together are used for the protection of transmission and distribution systems. Relays are classified in large based on the principle of operation. We have overcurrent relays, differential relay, frequency relay, etc. for which the operating quantity is … [Read more...]
