Description

4CH 4 Channel 12V Relay Module for PIC ARM AVR MSP430


This is a 4 channel relay module. It can be used to control the lighting, electrical and other equipments. The modular design makes it easy to expand with the Arduion board or other MCU board PIC, ARM and MSP430. The Relay output state by a light-emitting diode.

Specifications:

- Drive current: 20mA
- Control signal: 12V TTL level
- Maximum switching voltage: 150VAC 24VDC
- Dimension: 50mm*70mm*15mm

#define S0 2   //Control signal 1 -- Arduion D2
#define S1 3   //Control signal 2 -- Arduion D3

void setup()
{
  pinMode(S0, OUTPUT);
  pinMode(S1, OUTPUT);
}

void loop()
{
  digitalWrite(S0, HIGH);    //Open Relay 1
  digitalWrite(S1, HIGH);    //Open Relay 2
  delay(1000);
  digitalWrite(S1, LOW);     //Close Relay 1
  digitalWrite(S2, LOW);     //Close Relay 2
}
