12V 4-Channel Relay Board Optocoupler Module for Arduino Raspberry Pi ARM

  • Rs. 190.00 INR



  • Material: Metal+ Plastic
  • Color: As pictures show
  • Size: Approx. 72x 55x 19mm (Lx Wx H): 2.83x 2.17x 0.75inch
  • Switching Capacity: 10A
  • Maximum Voltage: AC250V / DC30V



  • Relay modules suitable for switching of higher voltages and perfect for use with microcontrollers including Arduino, ARM, AVR and PIC.
  • The relays used are rated up to 10A and have NO/NC contacts. Each channel has an LED indicator to show the relay is on.
  • Connects directly to a microcontroller
  • LED Indicator for each channel


Module description: 

  • The module uses genuine quality relay, normally open interfaces Maximum load: AC 250V/10A, DC 30V/10A;
  • Using SMD optocoupler isolation, driving ability, stable performance; trigger current 5mA; 
  • The module Operating voltage 12V; 
  • The module can be high or low by a jumper setting trigger; 
  • Fault-tolerant design, even if the control line is broken, the relay will not operate; 
  • The power indicator (green), the relay status indicator (red) 
  • The interface design of human nature, all interfaces are available through a direct connection terminal leads, very convenient 


Module interface: 

  • DC+: positive power supply (VCC) 
  • DC-: negative power supply (GND) 
  • IN1, IN2, IN3, IN4: can be high or low level control relay 
  • S1, S2, S3, S4, high or low level 


Relay outputs: 

  • NO1, 2, 3, 4: normally open relay interface 
  • COM1, 2, 3,4: Common Interface Relays 
  • NC1, 2, 3, 4: normally closed relay interface 


High and low level triggers options: 

  • It is low level trigger when jumper connect to LOW pin 
  • It is high level trigger when jumper connect to HIGH pin



  • Supports all MCU control 
  • The industrial field 
  • PLC control 
  • Smart home control
