Short Description :
When using the Arduino do interactive projects, a lot of heavy current or high voltage equipment is usually not directly use the Arduino digital IO port control(such as solenoid valves, lights, motors, etc.), can consider to use solutions of relay.
Arduino Relay shields is to use pine le Relay with high quality, provide 4 road input and output, the highest can meet 250 v / 10A communication device Or dc 24 v /10A equipment, thus can be used to control lights, motors, etc.
Modular design makes it easy to plate is connected with the Arduino extension. Relay output state is represented by a light emitting diode, convenient and practical use.
It is double-sided compacted PCB and it is also high quality.
It has Opto-Isolated inputs. And optoisolated inputs mean digital electronics are safe and noise-free.
This 6 relay module board is active low 5V.
This board consists of 6 relays, and this board can be controlled directly by a wide range of microcontrollers such as Arduino, AVR, PIC, ARM, PLC, etc.
These relays are used to control various appliances and other equipment with large current.
Its maximum output contact is AC 250V, 10A, and DC 30V 10A.
Its standard interface can be directly connected with the microcontrollers.
There are red working status indicator lights and it shows the safe use of the conductive.
It is widely used for all MCU control.
It is also used in the industrial sector, PLC control, smart home control.
This is a 5V, 10A 2-Channel Relay interface board. It can be used to control various appliances, and other equipments with large current. It can be controlled directly with 3.3V or 5V logic signals from a microcontroller (Arduino, 8051, AVR, PIC, DSP, ARM, ARM, MSP430, TTL logic).
It has a 1×3 (2.54mm pitch) pin header for connecting power (5V and 0V), and for controlling the relay. The pins are marked on the PCB:
