Description of product: Iduino 2 relays module - channels with optical insulation
Module with two SRD-05relays with the coil powered with a voltage of5 Vandoptical insulationof the input, and with the mounting holes. The system allows you to controlactuators using the microcontroller ports or any development kit.
The connection of the relays module
For proper operation, it is sufficient to connect the power of the relay coil and the digital control signal. Pins are the standard goldpin straps with the pitch of 2.54 mm, which enable the connection using the popular connecting cables. For connecting the actuator, use the ARK screw connection.
The relay has the following pins
- VCC- power of the optoinsulation
- COM- power supply of the relay coil, by default it is connected to GND by jumper
- IN1, IN2- control input of the relays, activated by the low status
- GND- ground of the system, all the GND pins are connected together
- KF (ARK)connectors- the relay contacts are connected in accordance with the pattern on the board of the module.
Examples of the application of the relay
- Driver of the lighting
- The driver of the actuators
- Switch for electric devices, includingthe motors
