6. It is an active low pin, meaning the relay will be activated when you pull the pin LOW and it will become inactive when you pull the pin HIGH. Pin details . Once is the Trigger Voltage, this is the voltage required to turn on the relay that is to change the contact from Common->NC to Common->NO. Mains Voltage Connections. Used in Automobiles electronics for controlling indicators glass motors etc. It has a standard interface that can be controlled directly by microcontroller. JD-V CC. // Each relay is turned on for 2 seconds and then off. 4-channel 5V USB Relay Module. Used to trigger(On/Off) the Relay, Normally one end is connected to 5V and the other end to ground, Common is connected to one End of the Load that is to be controlled, The other end of the load is either connected to NO or NC. Using a relay module with a different number of channels is similar. Available in one, four and eight channel versions, these modules can switch up to 10A per channel. Very powerful and easy to use. Input ground reference. Then connect the signal pin of the relay module with the pin 12 of the Arduino. Build your Own Thermometer with ThingSpeak; Wiring the VISHAY VEML6030 High Accuracy Ambient Light Digital Sensor; Wiring the Broadcom APDS 9253 001 Digital RGB IR â¦ If connected to NO the load remains disconnected before trigger and if connected to NC the load remains connected before trigger. Or is it my code? This is a 5V 4-channel relay interface board, and each channel needs a 15-20mA driver current. Pin 11 -----IN2. 5V Single channel Relay Module Pinout.

The 120-240V supply current enters the relay at the common (C) terminal in both configurations. Introduction This is a 4- hannel Relay interface board that allows you to control various appliances, and other equipmentâs with large current. Since the relay has 5V trigger voltage we have used a +5V DC supply to one end of the coil and the other end to ground through a switch. The one you use will depend on whether you want the 5V signal to turn the switch on or turn the switch off. The four and eight channel versions even have optical isolation to protect your DuinoTECH. It is equipped with highcurrent relays that â¦ Supporting RS232 and Ethernet communication mode. Using a relay module with a different number of channels is similar. Temerity. The above circuit shows a bare-minimum concept for a relay to operate. So, connect the 5V and the ground of the Arduino with the 5V and the ground of the relay module. If connected to NC the load remains connected before trigger, The other end of the load is either connected to NO or NC. To use the normally open contacts, use the NO terminal. Let us learn how to use one in our circuits based on the requirement of our project. How to use a Relay. 3V Relay, 5V Relay, 1-channel Relay module, 4-channel Relay Module. GND is the ground connection. The circuit which powers the coil is completely isolated from the part which switches ON/OFF, This provides electrical isolation. For demonstration purposes, letâs take a look at the pinout of a 2-channel relay module. For example, I would like to have the relays switching in sequence, putting LED's on at the same time. Thanks Brian P.S. 1. V CC. Input for isolated power supply for relay coils. Single-Channel Relay Module Basic Trouble Shooting. IN1.

Input ground reference. The purpose of the diode is to protect the switch from high voltage spike that can produced by the relay coil. 2. Control Pins: IN pin is used to control the relay. The default state of the relay when the power is off for COMM (power) to be connected to NC (normally closed), this is the equivalent of setting the 4 Relay boards IN pin to HIGH (has +5v sent to it) It is a safety feature to notuse the NC connector in-case you Arduino looses power it will automatically turns off all the devices connected to the relay. In this example, we will connect the relay module with Arduino in the normally open state. If connected to NO the load remains disconnected before trigger. It is known as a single channel because only one relay is used and it operates on 5V. This switch can be anything from a small transistor to a microcontroller or a microprocessor which can perform switching operating. KC868-H4, KC868-H2, KC868-H8, KC868-H32 controller are KC868 series of KinConyâs products, so phone APP and PC software are compatible. So I am designing a simple project where my Arduino reads analog values from a potentiometer, or rotation sensor, as it is called on EBay, and uses that value to determine how many relays to close.
