Description
The module allows to control the actuators consuming the current up to 10 A using the microcontroller's ports or development set (e.g. Arduino). In the system is a transistor amplifier which allows you to control the relay directly from the microcontroller's port (5 V). The relay activation is signaled by turning on of the corresponding LED.
For proper operation, it is sufficient to connect the power supply of the relay and the digital control signal. Pins are the standard goldpin straps with the pitch of 2.54 mm which allows for the connection using the popular connecting cables.
To connect to your Raspberry Pi, we recommend you to use theversion with optical insulation. |
Examples of application
- Driver of lighting
- The driver of actuators
- Switch for electric devices, including motors
Connection
The module has three input pins VCC, GND, IN1, IN2, IN3, IN4. For the system to work correctly, you must connect the power supply of 5 V to the VCC pin, ground GND and the input signal INx.
Output pins are marked as NO - disconnected by default, NC - by default, it is connected with COM. Indicating the low status at the INx pin, switches the relay contacts and makes the connection between the COM and the NO, disconnecting the COM from the NC.

30 days to return, without giving a reason
If the product does not meet your expectations, you have 30 days from receiving the parcel to withdraw from the contract. The product only has to be complete. The right of return belongs to consumers (a purchase unrelated to business activity).
Complaints
If the product turns out to be faulty, you can make a claim under the guarantee or the statutory warranty. We handle claims without delay, at the latest within 14 working days of receiving the report together with the goods.
Question: When a switching signal is given, does this set of x4 and smaller x2 relays hold the changed state of the contacts (is it bistable)? Does it require a continuous holding signal?
Question: Good day does the relay come with an optisolator to protect the arduino / raspberry pi?
