5V 2 Channel Relay Module Shield

Iduino 2 relays module - channels with optical insulation

Module with two SRD-05 relays with the coil powered with a voltage of 5 V and optical insulation of the input, and with the mounting holes. The system allows you to control actuators 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 gold pin 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 opto insulation
• 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 high 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
