Relay Module 10A 8 Channel

Relay Module 10A 8 Channel -You may use a relay in controlling high-voltage and current that your Arduino could not, may it be AC or DC. This 8 channel relay can handle voltages of 10A@250VAC or 10A@30VDC.. A relay is a digital switch. What it does is to allow a current to flow or not using the signal is received. It has 3 terminals, the Common, Normally Open, and, Normally Close Terminal. It also has 1 coil that does the cutting or letting the current flow.

Circuit Rocks brings the 8-Channel Isolated 5V 10A Relay Module for users who desire to implement some unique microcontrollers in projects. The digital switch is controlled by a greater range of microcontrollers, including Arduino, AVR, PLC, ARM, and PIC, etc. The unit is capable of handling plenty of appliances and other equipment that reflect large currents. When it comes to considering the relay output maximum contact, it appears as AC250V 10A and DC 5V 10A.

As for the terminals, the Common Terminal and the usually Close Terminal have continuity without energizing the coil. Energizing the coil, the Common Terminal, and the Normally Open Terminal creates the continuity and cuts the connection to the Normally Close Terminal.

If you need a fewer set of the relay, we have the 1 channel, 2 channel, 4 channel. For more channels here is the 16 channel version.


  • Control Voltage: 5V DC
  • Max Control Capacity:10A@250VAC or 10A@30VDC

Furthermore, the 8-channel relay module hosts 3 terminals such as the Common, Normally Closed, and Normally Open. The dedicated single-coil helps cut and let the current flow follows its prescribed path. The most astonishing part is that it presents itself with a comprehensive range of applications. One can derive the services of the Relay Module for all MCU control, smart home control, PLC control, and industrial sector.

Enthusiasts can switch to this sort of 10A relay module on Raspberry Pi. This neat relay mechanism houses 8 x 5V relays rated at 10A/250V each. There are 8 channels on the board to give you access to multiple units to be the best fit for Arduino and Raspberry Pi projects. It is a 5V 8-channel Relay Module with a Normally Open interface. Further, the module reflects a trigger current of 5mA as well as a module working voltage of DC 5V. A jumper triggers every single channel of the module to adjust the setting across high and low levels.

Relay Module 8-Channel – Features

The relay module is designed in a way that it will not move even upon the disconnection of the control line. The status indicators are presented in terms of green and red color lights. The green-color light indicates the power utilization while the red-color light indicates the 6-channel relay status. It allows users to connect all module-size interfaces through the terminal block. Thus, it seems quite practical and convenient.

In terms of features, the 8-channel system publishes a remarkable blend of valuable features and specifications. Some of the key highlights are as given below:

  • First, the 8-channel Relay Module has the ability to control both AC and DC appliances i.e. motor, solenoids, lights, and fans, etc.
  • It equips an LED status indicator to convey the relay ON/OFF status.
  • Also, it brings mounting holes for installation.
  • There’re high-quality screw terminals for easy and quick connection establishment.
  • It has the potential to control directly all kinds of equipment and load.
  • Further, the relay module houses the Input Signal Pin to burg stick for convenient accessibility.
  • It provides a signal input for a high-level signal.
  • Moreover, it also offers the facility to protect your microcontroller with a freewheeling diode.
  • Users can open a normally closed contact.
  • It is more convenient to execute the Blue KF301 terminal line.
  • Likewise, the relay module controls various sorts of appliances and other equipment.

Frequently Asked Questions

Q1: How is the Relay put to use?

As was already explained, a relay is an electric-powered switch that opens when two contacts are separated and closes when they come into contact. The relay will stop if the setting is high, enabling current to flow although there are many different kinds of relays, electronic relays are the most frequently utilized, and therefore we'll discuss them and their operation. They are made up of contacts, armatures, and coils.
The magnetic force causes the armature to move when the coil is activated, opening or closing the contact. A terminal for input or output is connected to each contact. Pole and Throw are the names of the input and output terminals, respectively. The relay is classified into different categories depending on how many terminals it has. The SPST and SPDT are the most often utilized. Let's examine how the SPDT and SPST operate.

Q2: What varieties of relay modules are there?

Not to mention, Grove compatibility exists for all electromechanical relays. Grove is a modular, standardized connector prototyping solution that streamlines project connection, experimentation, and construction. The relay possibilities you can think about are listed below.

1 Relay – Grove
This is a basic electromechanical relay with a maximum switching voltage of 250VAC/30VDC and a maximum current of 5A. It can operate on low voltages like 3.3V, like the ESP32, ESP8266, etc., or 5V, like your Arduino.
On the board, there is an indicator LED that will turn on when the regulated connections are closed.
This SPST relay is excellent for uses that merely require an on or off position.

2 Channel SPDT Relay Grove
Two single-pole, double-throw (SPDT) switches are included in the Grove – 2-Channel SPDT Relay. To operate the switches, only low voltage and low current impulses are needed. For example, you can control up to 250V AC or 110V DC with 5V DC.
The ability to manage the two channels independently is the best feature. For instance, COM1 can be connected to NC1 or NO1 as desired when directed by SIG1.
It can be used in large-scale products or projects that require the switching of high voltage/high electronic solutions since it is so practical and dependable.

4 Channel SPDT Relay for Groove
Similar to the 2-channel SPDT relay, the 4-channel SPDT relay has four single-pole, dual throw (SPDT) switches that can be controlled by low voltage, and low current signals alone.
To regulate the channels independently, we use an integrated STM32F030F4P6. The I2C interface is used to deliver the control command, which the on-integrated STM32F030F4P6 will interpret so you may regulate the switch you desire.
