Product information "RELAY click"

RELAY click can control various devices with up to 5A, 250V AC/30V DC loads. It features two G6D1AASI-5DC power PCB relay modules. The click is designed to run on 5V power supply only. RELAY click communicates with the target microcontroller via mikroBUS™ PWM (RL1) and CS (RL2) pins.

RELAY click is a compact and easy solution for adding a relay to your design. The two screw terminals onboard allow seamless connectivity.


Note: RELAY click has exposed pins/pads. To stay safe take precaution when applying high voltage to the click. The click is to be used by trained personnel only when applying high voltage.

G6D1AASI-5DC power PCB relay

The maximum contact resistance of the G6D1AASI-5DC relay is 100 mΩ.

Communication lines

Communication lines voltage level can be in range between 3.3V and 5V. On-board transistors are used to drive relays by current sinking.

Relay information

A relay is an electrical switch used to terminate or establish a circuit using a low power signal from a microcontroller. It provides complete electrical isolation between microcontroller and controlled circuits. Use the RELAY click™ board with its two G6D1AASI-5DC relays to control various devices with up to 5A, 250V AC/30V DC loads.

Code examples that demonstrate the usage of RELAY click with MikroElektronika hardware, written for mikroC for ARM, AVR, PIC and PIC32 are available on Libstock.

The following code snippet is a simple example of RELAY click toggled with buttons on an EasyPIC v7.

 1 sbit Relay1           at  LATC1_bit;
2 sbit Relay2           at  LATE0_bit;
3 sbit Relay1_Direction at TRISC1_bit;
4 sbit Relay2_Direction at TRISE0_bit;
5 void main()
6 {
7     Relay1_Direction = 0;                      // Set relay direction as output
8     Relay2_Direction = 0;                      // Set relay direction as output
9     Relay1 = 0;                                // Turn off relay1
10     Relay2 = 0;                                // Turn off relay2
12     while( 1 )
13     {
14         if( Button( &PORTB, 0, 80, 1 ) )       // Toggle relay 1 on B0 button press
15             Relay1 = ~Relay1;
17         if( Button( &PORTB, 1, 80, 1 ) )       // Toggle relay 2 on B1 button press
18             Relay2 = ~Realy2;
