RELAY Click is a compact add-on board with general-purpose relays that any host MCU can control. This board features two G6D1AASIDC5s, slim miniature relays from OMRON. The relays offer low power consumption in a small, lightweight package with PCB pin mounting, which in some cases allows socket mounting. It comes with a dimension of 17.5×6.5×12.5 millimeters (LxWxH) and an SPST-NO contact arrangement with a coil voltage of 3VDC, providing a maximum switching voltage of 125VAC/60VDC. This Click board™ makes the perfect solution for the development of controlling high-power applications and can also be used to activate various electromotors, switch on the lights, or power the entire embedded system.

RELAY Click is fully compatible with the mikroBUS™ socket and can be used on any host system supporting the mikroBUS™ standard. It comes with the mikroSDK open-source libraries, offering unparalleled flexibility for evaluation and customization. What sets this Click board™ apart is the groundbreaking ClickID feature, enabling your host system to seamlessly and automatically detect and identify this add-on board.

Volitage

Note: RELAY Click has exposed pins/pads. To stay safe, take precautions when applying high voltage to the Click board™. This Click board™ needs to be used by trained personnel only while applying high voltages.

How does it work?

RELAY Click is based on two G6D1AASIDC5s, slim miniature relays from OMRON. Despite its size, the G6D-1A-ASI DC5 relay can withstand up to 5A and 220V AC/30V DC. It can endure up to 300,000 operations, with 30V DC and 2A. This relay has a single pole only – when the coil is energized, it will attract the internal switching elements and close the circuit, similarly to a switch. These relays are designed so relatively low currents and voltages can easily activate their coils. For the G6D-1A-ASI DC5 relay operated at 5V, the coil current is 40mA. This makes them a perfect choice for activating them by an MCU.

MikroE Miscellaneous Relay click

RELAY Click uses GPIO pins RL1 and RL2 to be controlled by the host MCU. Since RELAY Click uses an NPN RET and resistors, the host MCU is safe from the current spikes driving the relay’s coils. In addition, there is an LED for every relay, each of a different color, representing the relays’ status.

This Click board™ can be operated only with a 5V logic voltage level. The board must perform appropriate logic voltage level conversion before using MCUs with different logic levels. Also, it comes equipped with a library containing functions and an example code that can be used as a reference for further development.

Software support

We provide a library for Relay click on our LibStock page, as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.

Library Description

The library offers an option to control the state of relays.

Key functions:

void relay_relay2Control( uint8_t pinState ) – Controls the Relay 2 pin.

void relay_relay1Control( uint8_t pinState ) – Controls the Relay 1 pin.

Examples Description:

The application is composed of three sections:

System Initialization – Sets pin directions.
Application Initialization – Initializes driver.
Application Task – Turns relays on and off.

void applicationTask()
{
relay_relay2Control ( 1 );
relay_relay1Control( 1 );
mikrobus_logWrite("Relays turned on", _LOG_LINE);

Delay_ms(1000);

relay_relay2Control ( 0 );
relay_relay1Control( 0 );
mikrobus_logWrite("Relays turned off", _LOG_LINE);

Delay_ms(1000);
}

The full application code, and ready to use projects can be found on our LibStock page.

Additional notes and information

Depending on the development board you are using, you may need USB UART click, USB UART 2 click or RS232 click to connect to your PC, for development systems with no UART to USB interface available on the board. The terminal available in all MikroElektronika compilers, or any other terminal application of your choice, can be used to read the message.

mikroSDK

This click board is supported with mikroSDK - MikroElektronika Software Development Kit. To ensure proper operation of mikroSDK compliant click board demo applications, mikroSDK should be downloaded from the LibStock and installed for the compiler you are using.
