30A High-Current 1-Channel Relay Module

  • RM12.50

  • Product Code: FC-65 Relay Module Board
  • Availability: In Stock

 

The module adopts high-quality 30A relay, and the maximum load is normally open interface: AC 250V/30A, DC 30V/30A;

 

Features:

  • SMD optocoupler isolation
  • Good in safety. In power system and high voltage system, the lower current can control the higher one, able to control various appliances and other equipment with high-current current.
  • Standard interface that can be controlled directly by microcontroller (Arduino, 8051, AVR, PIC, DSP, ARM, ARM, MSP430, TTL logic).
  • Green indicator LEDs for Power status
  • Red indicator LEDs for Relay output status.
  • With a normally-open (NO) and a normally-close (NC) contact.
 

Specifications

  • Number of Relays: 1
  • Working voltage: 5V DC
  • Control signal: TTL level
  • Static current: 5mA
  • Working current: 190mA
  • Trigger current: 2 – 4mA
  • Rated load: 7A/250VAC; 10A/125VAC; 10A/28VDC;
  • Contact action time: 10ms/5ms
  • Current: 15-20mA per channel

 

Pinouts

  • DC+ : DC power supply positive pole
  • DC- : DC power supply negative pole
  • IN : signal triggering pin
  • JD+ : relay control voltage positive
  • JD- : relay control voltage negative
  • DC+ and JD+ shorted by jumper cap, DC- and JD- shorted with jumper cap, it is the same voltage between trigger terminal and relay control terminal
  • High and low level trigger mode selection.Jumper and L pin connection, IN pin is low level triggerJumper and H pin connection, IN pin is high level trigger
  • Normally closed pin (NC) : relay normally closed pin
  • Common pin (COM) : relay common pin
  • Normally opened pin (NO) : relay normally opened pin
  • Rated current of the interface is 16A

The Sketch

Enter the following sketch, upload it and go to town.
If you open your Arduino serial monitor you will be able to see the voltage.

void setup(){
   pinMode(7,OUTPUT);
}
void loop() {
   digitalWrite(7, HIGH);
   delay(2000);
   digitalWrite(7,LOW);
   delay(2000);
}
