  • Sale
  • Regular price Rs. 450.00
Tax included.

This relay module is 5V active low.
It is a 4-channel relay interface board, which can be controlled directly by a wide range of microcontrollers such as Uno AVR, PIC, ARM, PLC, etc.
It is also able to control various appliances and other equipment with large current.
Standard interface can be directly connected with microcontrollers.
Red working status indicator lights are conducive to the safe use. Widely used for all MCU control, industrial sector, PLC control, and smart home control. Module features are as follows:
1. Standard For Shield interfaces and shape
2. Can continue to stack other For expansion boards
3. 3 M3 screw positioning holes for easy installation
4. High Drive (5V or 3.3V) normally open contact closure
5. Onboard relay indicator (red)
Special Note: When using the For UNO board connected to it, because UNO USB interface is extremely high, should avoid green terminals are shorted its shell.
Relay Shield Interface: (the last picture show)
Relay: sky- 5V DC relay , model HJR-4102-L-5V, which Relay1 behalf of the 1st relay , the other and so on.
Power Interface : 5V DC power interface
Indicator: four lights are red when the relay is driven high , the corresponding indicator will light up .
Relay Terminals: Terminal high-power , high-current high voltage can be connected to the device .
The 1st foot ( i.e. 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.
