Description

R1 5V to 10A/250V relay module – with optoisolation for Arduino – 1 channel

Universal 5V relay module with optoelectronic isolation for 10A – 250VAC / 10A – 30VDC.

The circuit allows you to control the actuators using the ports of the microcontroller or any runner kit.

The module is supplied with 5V to the corresponding VCC and GND pins.

Thanks to the use of opto-isolation, the current consumption of the channel is minimal, so you can easily control the microcontroller, o relay activation is indicated by the relay channel operation status LED.

When the power is connected, the power LED lights up.

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

Product features

• Module equipped with SRD-05 relay with coil powered by 5 V with optical input isolation.
• The module allows the control of actuators drawing up to 10 A using the ports of a microcontroller or any Arduino development kit.
• Opto-isolation separates the control signal from the relay power supply part, thus ensuring the safety of the control system operation.
• Application for contact boards, runtime modules, arduino, etc.
• For proper operation, all you need to do is connect the relay power supply and the digital control signal.
• LOW state switching
• Application examples:
  • Lighting controller
  • Controller of executive systems
  • Switch for electrical equipment including motors
