  • What Are Electronic Timing Relays? a Relay Is an Electromagnetic Switch Which Operates on a Small Electric Current
    What Do You Know About Electronic Timing Relays? There are certain components that form the core of the modern control systems. One such important component used in many applications is an Electronic Timing Relay (ETR). Let us start by understanding some basics. What are Electronic Timing Relays? A relay is an electromagnetic switch which operates on a small electric current. These switches are used to turn on or off a circuit of higher amperage. When electricity is applied, the electromagnetic coil causes the armature to move, opening or closing the contacts, controlling the flow of electricity from a high current source connected to the load side of the relay. Relays act as bridges that activate larger currents using smaller ones. This allows you to use a relay to safely switch on and off different devices. An Electronic Timing Relay has circuitry integrated which controls the armature motion upon input voltage being applied. This addition gives the relay the property of time-delay actuation. Electronic Timing Relays are constructed to delay armature motion on coil energization, de-energization, or both. ETRs provide a wide range of selectable functions so that users can customize their specific machine operation. Relay Components and Operation What are the Best Features of Electronic Timing Relays? Electronic timing relays are used in a number of electronic applications, owing to the unending list of their features, which are as follows: • Multi-function timer, which allows the user to adjust between multiple timing functions. • High duty cycle applications. • DIN rail or panel mounting. • Resistant to mechanical shock and vibration.

  • Experiment (1) Principles of Switching
    Experiment (1) Principles of Switching Introduction When you use microcontrollers, sometimes you need to control devices that requires more electrical current than a microcontroller can supply; for this, electrical relays and transistors are used. In this experiment, we will investigate two types of switching; electromechanical switching and solid state switching. Objectives This experiment aims to: 1- Understand the basic principles of switching devices. 2- Introduction to electromechanical switching as well as solid state switching. 3- Understand the advantages and disadvantages of each type. 4- Study the relative speed of different type of switches. Theory Electromechanically Relays Relays are electromechanical devices that use an electromagnet to operate a pair of movable contacts from an open position to a closed position. The relay is a switch that is controlled by a small electric current. It can be used to control motors, heaters or lamps circuits which themselves can draw a lot more electrical power. Figure 1 shows the circuit symbol for a relay. Figure 1: Circuit symbol for a relay In figure 2, the relay’s coil is energized by the low-voltage (12 VDC) source, while the single- pole, single-throw (SPST) contact interrupts the high-voltage (480 VAC) circuit. It is quite likely that the current required to energize the relay coil will be hundreds of times less than the current rating of the contact. Typical relay coil currents are well below 1 amp, while typical contact ratings for industrial relays are at least 10 amps. Mechatronics Systems Design Lab Figure 2: Relay drive an AC load One relay coil/armature assembly may be used to actuate more than one set of contacts.

  • Inductive Load Arc Suppression Application Note
    Application Note: Inductive Load Arc Suppression Figure 2. Introduction Bidirectional TVS Diode When a reed switch or reed sensor is used to control an Reed Switch/Sensor inductive device (relay coil, solenoid, transformer, small motor, etc.), the energy stored in the inductance in the device Load will subject the switch contacts to a high voltage when the reed switch opens. When the switch contacts open, the contact gap is initially small. Arcing across this contact gap RL can occur immediately after the switch opens. This can TVS Vs happen in resistive as well as inductive loads, but inductive loads generate a higher voltage and this causes increased L arcing. Increased arcing decreases switch life. Direct current (DC) inductive circuits typically use a diode to prevent the high voltage. The diode in the circuit is called a suppression diode, flyback diode, freewheeling diode, or catch diode. However, a diode cannot be used in an alternating current (AC) circuit. AC arc suppression requires the use of a RC suppression has the advantage of limiting the switch metal-oxide varistor (MOV), a bidirectional transient voltage contact voltage at the time of switch opening when the suppressor (TVS) diode, or an RC suppression network.

The various be used to reduce arcing and improve life in resistive arc suppression methods have various advantages and loads. With RC suppression, a seriesconnected capacitor disadvantages.
