On Delay Timer Connection:

This diagram shows On delay timer connection. In this circuit, we use an SP MCB, an On delay timer, a magnetic contactor, and a three-phase motor. This circuit diagram is very simple and easy to make connect it. If you want to know more about this circuit, please check our youtube video below the post.

Components used to make the On Delay Timer Connection:

01. SP MCB:

In single-pole MCB, Switching and protection are Affected in only one Phase. Single phase supply to break the phase only. A single Pole breaker is Typically used with 120-volt Circuits, and a 6-20 amps Miniature Circuit Breaker. They are constructed with one Line Wire and one Neutral wire. A Single Pole switch is the most basic General-Purpose switch that you use to Control a light or another device from one location. These Switches have 2 Brass-Colored screw Terminals Connected to the hot Power source wires. Pole refers to the number of Circuits Controlled by the Switch SP Switches Control only one Switch Electrical Circuit.

02. On delay Timer:

A timer is a type of time-switching device that controls and controls Electrical circuits and electrical and electronic devices through time setting (on/off). The timer is basically 8-pin. Like other controlling devices the timer has a coil and when this coil is magnetized, the timer works on/off. The timer has 2 common ends and each common end has normally close and normally open options. When the timer is set by time, the timer trips at the end of that time and turns the common is normally closed (on) to open (off) and normally open (off) to close (on). This is how the timer works.

03. Magnetic Contactor:

A magnetic contactor is an electromagnetic switching device. It is generally used for controlling 3-phase Motors. The operation of a magnetic contactor is similar to that of a Relay. but a relay is used for low-power or low-voltage connections, and a magnetic contactor is used for high-power or high-voltage connections. As soon as the supply is applied to the magnetic contactor coil. its normally open contacts are closed and normally closed contacts are opened and the associated devices are also operated. This is how a magnetic contactor works.

04. 3 Phase Motor:

A 3-phase electric motor uses a 3-phase Power Supply to Convert Electric Energy into Mechanical Energy. It contains four Wires (Three hot Wires and one Neutral Wire) and Uses 3 Alternating Currents of the Same Frequency. Since it Generates a Rotating Magnetic Field, it does not need a Capacitor for the Startup. Some 3-phase Motors are Reversible, Which Means they can serve as Generators by Turning Mechanical Energy into Electrical Energy.

Frequently asked questions

How does a delay on make timer work?

As soon as the pushbutton is pressed, the relay coil would de-energize. Continue to hold the pushbutton or the coil will stay de-energized. As soon as you take your finger off the pushbutton of the switch the time delay begins. After the set time delay, the relay coil is energized or is ready for the next command.

What are the advantages of an on-delay timer?

The output contacts remain closed until the input coil is de-energized and the preset time elapses, whichever comes first. The advantage of an on-delay timer is that it can prevent unwanted or premature actions by creating a time gap between the input or output signals.

What is the delay in making it?

also called On Delay, Delay on Operate, and Delay on Energization. Application of the power to the timer input voltage terminals starts the time delay cycle. At the end of the preset delay, the output transfers until it is reset by interrupting the input of the voltage.

What is on delay timer in PLC?

On delay means that once a timer has received a power supply on signal, its output will change state after a predetermined delay. The timer would be ON when a start input signal is received, and when a preset timing is reached, the signal state of the output changes from 1 to 0.

What are the two types of on-delay timers?

The timing contacts for the on-delay timer could be either normally open, timed to close (NOTC), or normally closed, timed to open (NCTO). On-delay timers delay their action when the coil is energized or revert to their original state instantly when de-energized.
