Timer Relay wiring diagram:

This diagram shows how to make a timer relay wiring diagram. In this circuit, we use a DP MCB (Double Pole Miniature Circuit Breaker ), an 8-pin timer relay, an NC button and NO button, and an exhaust fan. First, we need to connect the DP MCB with the power source, then input connection with timer and NO, NC buttons. And lastly, we need to connect the exhaust fan to this circuit. Now our circuit is ready for use. if you want to know more about this circuit please check our youtube video below the post.

Components used to make the Timer Relay wiring:

01. DP MCB:

DP MCB In Two Pole MCB, switching & protection is affected in phases and the neutral. A Double Pole or DP Switch is a Switch that Controls two Circuits at the same time. In terms of Residential Switching, this Normally means it Switches the live and Neutral at the same time. In Layperson Terms, Double Pole switches or DP Switches are Exclusively Designed to Control two Different Electrical Circuits at the same time, which allows the Appliances to Isolate in a safe and reliable manner. Fan or light Combinations and Medical Equipment are some of the many applications for DP Electrical Switches.

02. 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 two 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’s normally closed (on) to open (off) and normally open (off) to close (on). This is how the timer works.

03. NO/NC Button:

NO (Normally Open) Terms Refer to a Type of Dry Contact or Wet Contact. A ‘Push to Make’ Switch Allows Electricity to flow Between its two contacts when held in. When the button is released, the Circuit is broken. This type of Switch has also known as A Normally Open (NO) Switch. As its name implies, a Normally Open (NO) Switch Contact or “a Contact” is a Switch. Put very simply, a Normally Open Sensor will have no Current When in a Normal State But When it Enters an Alarm State it will have +5V applied to the Circuit.

04. Exhaust Fan:

An exhaust fan is a device that removes bad air from a room. It is a mini fan that has a good speed and it removes the bad air naturally, it uses in the kitchen or small room, mosque, hall room, etc. It uses in single-phase or 3-phase lines. An exhaust fan can control very easily. Air circulation is crucial since it reduces/eliminates odor and humidity problems in all of the rooms. Modern building infrastructure may not even provide enough space for them to have adequate ventilation. It is crucial to have proper ventilation in areas like the kitchen and bathroom. Since the majority of the activities that take place in these rooms produce unpleasant odors and airborne pollutants that must be removed. An exhaust fan is the most effective tool or appliance for this task.
