8 pin relay with flowmeter:

This diagram shows how to make 8 pin relay with a flowmeter. In this circuit, we use a relay, a flow meter, a single-phase motor, a DP MCB ( Double Pole Minature Circuit Breaker ), and an RCCB ( Residual Current Circuit Breaker ). This circuit is very simple and easy to make. if you want to know more about this circuit please check our youtube video belwo the post. Stay with our website for more updates.

Components used to make the 8 pin relay with flowmeter:

01. Rlay:

The most popular relay for automation work is the 8 Pin Relay. The 8-pin relay has a DC or AC coil as the main part. which is connected to two pins. There are two common parts. Underneath a Common part are a NO and an NC part. No part is normally open with a common part and the NC part is normally closed. The timer base used for automation is the same as the 8-relay base. That is, switching can be done using the timer base. This is basically how a relay switch works for the relay.

02. Flowmeter:

Water flow meters are devices used to measure the volume or mass of fluid that passes through a pipe for water. They are commonly used in water flow treatment and distribution systems, irrigation, and industrial processes. There are several types of water flow meters set, including positive displacement meters, turbine meters, ultrasonic meters, and magnetic meters. A water flow meter measures the total volume of fluid that has passed through a pipe over a certain time. A water flow sensor, on the other hand, measures the velocity of the fluid flow at a specific point in time. It is mainly used to monitor the flow rate in real-time, to detect any changes or irregularities in the water flow, and to regulate or control the flow as needed.

03. DP MCB:

DP MCB In 2 Pole MCB, switching & protection is affected in phases and the neutral. A Double Pole or DP Switch is a Switch that Controls 2 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 2 Different Electrical Circuits at the same time, which allows the Appliances to Isolate safely and reliably. Fan or light Combinations and Medical Equipment are some of the many applications for DP Electrical Switches and Electrical components.

04. RCCB:

The Residual Current Circuit breaker RCCB is the Safest device to detect and Trip against Electrical Leakage current. This ensures protection against Electric shock Caused by indirect contact. Circuit breakers (CB) are automatically Operated Electrical Switches that Protect Electrical Circuits from Short-Circuiting or Overloading systems. It Protects against many major accidents. RCCB Circuit Breaker is an Electrical Wiring device whose function is to disconnect the current in the circuit.

Frequently asked questions

How does an 8-channel relay work?

Using an eight-channel relay means that the relay module has 8 individual relays, each capable of controlling a separate circuit diagram. This allows for the centralized control of multiple devices or circuit diagrams using a single control signal.

Is the 8-channel relay normally open?

The Relay is a digital normally open switch that controls a relay capable of switching much higher voltages and current flow than your normal Arduino boards. When set to LOW, the LED would light up and the relay would close allowing the current flow to flow. The peak of the voltage capability is 250V at 10 amps.

What is the difference between 8-pin and 11-pin relays?

For example, an eight-pin cube relay has 8 contacts, whereas an 11-pin cube relay has 11 contacts. On both relays, 2 of the contacts are taken up by the coil but the 8-pin will have 2 “common” contacts, whereas the 11-pin has 3.

How does an 8-channel relay work?

Using an eight-channel relay means that the relay module has 8 individual relays, each capable of controlling a separate circuit. This allows for the centralized control of multiple devices or circuit diagrams using a single control signal.

How do I know if my 8-pin relay is bad?

You could take each probe on the multimeter and touch either corresponding switch pins or you should hear a beep to indicate continuity between the pins. If you do not hear a beep, your switch pins are stuck open or the relay is bad.
