  • High-quality relay
  • Normally open
  • Maximum load: AC 250V / 10A, DC 30V / 10A;
  • Optocoupler isolation,
  • Stable performance
  • trigger current 5mA
  • Can be set by jumper high or low trigger
  • Fault-tolerant design, even if the control line off, the relay will not move;
  • power indicator (green), relay status indicator (red)
Two module interfaces:
  • VCC+: then the power supply positive (voltage according to the relay requirements 5V)
  • GND: connected to the power supply negative
  • IN: can be high or low-level control relay pull
Relay output:
  • NO: relay normally-open interface, relay pull before the suspension, after the connection with the COM shorted
  • COM: relay common interface
  • NC: relay normally closed interface, the relay before the connection with the COM short, pull after the suspension

The indicator LEDs (both power as well as the operational indicator) improve the operational feature of this module, as it provides a real-time feedback about the module’s state.  Below is your sample Arduino code, which blinks or switch on/off the relay module in the interval of 1 sec each:

int RelayPin = 6;

void setup() {
// Set RelayPin as an output pin
pinMode(RelayPin, OUTPUT);

void loop() {
// Let’s turn on the relay…
digitalWrite(RelayPin, LOW);

// Let’s turn off the relay…
digitalWrite(RelayPin, HIGH);
