DescriptionThe module allows the control of the actuators consuming a current of up to 10 A using the microcontroller’s port or any development kit, for example, Arduino and Raspberry through the low or high status selected by the jumper. Optoinsulation separates the control signal from the part associated with the relay’s power, thereby providing work safety for the management system.CONNECTIONIt is sufficient to connect the power to the relay coil and the digital control signal to the pins of the screw ARK connectors, which are linked by any cables with the insulation stripped at the ends, for appropriate functioning.
