NOx) is a normally open pin, NCx pin is normally closed, COMx is common, i.e., when the relay is not driven, NOx and COMx open between two pins, NCx and COMx connection When the relay (x) control signal pin is high drive relays, NOx and COMx connection open between NCx and COMx./* * Created by ArduinoGetStarted. Relay Terminals: Terminal high-power, high-current high voltage can be connected to the device. 3.Now you can control relays 1, 2, 3, and 4 in Relay Shield 2 using the Arduino’s 8, 9, 10, and 11 digital I/O pins. Indicator: four lights are red when the relay is driven high, the corresponding indicator will light up. Relay Shield 1 Digital Pins 8, 9, 10, and 11, are connected to Relay Shield 2 Digital Pins 7, 6, 5, and 4 respectively. Arduino 4 Relays Shield A000FREE delivery Fri, Jun 16 Or fastest delivery Tue, Jun 13 More Buying Choices 24. Note: Please ensure the back of the board is. Relay: sky- 5V DC relay, model HJR-4102-L-5V, which Relay1 behalf of the 1st relay, the other and so on. This shield plugs directly onto a standard Arduino footprint device, and you have 4 relays at your command. The max switching power DC 90W or AC 360VA gives direct control. With the onboard 4 control keys,you can also control the. This Arduino Shield is a completely newly designed that is able to control 4 relays at a time. It can be directly controlled by Arduino/Crowduino through digital IOs with an external 6.512V DC supply. The max switching power is 35VDC 70W for each channel. The shield provides two relays () called RELAY1 and RELAY2 commanded by pin 1 and pin 2 respectively.The shield also provides an easy connection by means of screw terminal blocks to A1 to A4 analog inputs, I2C and supply voltages. Special Note: When using the Arduino UNO board connected to it, because UNO USB interface is extremely high, should avoid green terminals are shorted its shell. The Relay Shield is an Arduino compatible smart module with 4 mechanical relays providing an easy way to control high voltage. The MKR Relay Protoshield allows you to easily add relays to your MKR board based project. High Drive (5V or 3.3V) normally open contact closure.Specifications: Operating voltage: 5V Coil current: 35 mA (for each relay. 3 M3 screw positioning holes for easy installation This Arduino 4 Relays Shield is a board with four individually controlled relays.Relays Relays allow low-power microcontrollers, to handle circuits that use much higher power than what the board can handle directly. Can continue to stack other Arduino expansion boards Arduino MKR family board ( link to store ).Standard Arduino Shield interfaces and shape.Relay Shield (ie 5V Quad Relay Module) is a small current signal control power equipment commonly used electronic module, enabling high-power single-chip control devices are widely used in SCM system to make smart home project and can be directly plugged into the Arduino compatible the use of various types of motherboards, eliminating the patch cable troubles.
