Relay module R1 5V to 10A/250V - with opto-isolation for Arduino - 1 channel Universal module with 5V relay with optoelectronic isolation for 10A - 250VAC / 10A - 30VDC.

The system allows you to control actuators using microcontroller ports or any development kit.

The module is powered by 5V to the appropriate VCC and GND pins. Thanks to the use of opto-isolation, the channel current consumption is minimal, thanks to which you can easily control the microcontroller, the relay activation is indicated by the relay channel operating status diode.

After connecting the power supply, the power indicator LED lights up.

The module is switched on by applying a low state LOW, i.e. ground to the signal input In1.

Product Features

The module is equipped with an SRD-05 relay with a 5 V powered coil with optical input isolation.
The module allows you to control actuators that draw current up to 10 A using microcontroller ports or any Arduino development kit.
Opto-isolation separates the control signal from the part related to the relay power supply, thus ensuring the safe operation of the control system.
Applications: breadboards, starter modules, arduino, etc.
For correct operation, it is enough to connect the relay power supply and the digital control signal.
Switching on with LOW state
Application examples:
- Lighting controller
- Actuator controller
- Switch for electrical devices including motors
