SKU:300000010736

The module is equipped with four relays with a coil powered with a voltage of 5 V with optical isolation of input and mounting holes. The system allows you to control actuators with microcontroller ports or any commissioning set.

Description: Relay module 4 channels with optoisolation – 10A / 250VAC contacts – 5V coil

The module allows to control the actuators consuming a current of up to 10 A using the microcontroller’s ports or any commissioning set (including Arduino, Raspberry Pi and STM32Discovery). Optical isolation separates the control signal from the part associated with the power relay, thereby providing work safety of the control system.

Connection

Connecting the power to the relay coil and the digital control signal is enough for proper operation. Leads are the standard strap goldpin pitch of 2.54 mm which enables connecting via connecting cables.

The relay has the following leads:

  • VCC– the power of optical isolator.
  • JD-VCC – the power of the relay coil, by default connected with the VCC through a jumper. To control the voltage of 3.3 V, disconnect the jumper, to the pin JD connect the power to the coil 5 V and to the VCC connect the voltage of 3.3 V.
  • IN1, IN2, IN3, IN4 – control inputs of relays attached by the low state.
  • GND– ground of the system, all GND leads are connected with each other.
  • Connectors KF (ARK)– the relay’s contacts are connected in accordance with the pattern on board of the module.
Examples of usage
  • Driver of light
  • The driver of executors
  • Switch for electric devices, including motors

    this module is active low which makes it the best module there is, why?
    it can work with any logic level device(tested) all you have to do it output low to the controlling pin when you need to activate the relay.
    if you don’t output anything(logic high) meaning you left it floating then it won’t activate randomly which is a nice surprise.
    ps: if you remove the yellow jumper then the relays won’t activate(switch) on signal which also a nice touch(gonna use 2n222 to disable the module when I want)
