Relay Module 5V (8 Channel)

Description: Relays module, 8 channels with optoisolator  – 10A / 250VAC contacts – 5V coil – blue

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

Connecting

For proper operation, it is sufficient to connect the power of the relay coil and the digital control signal. Leads are the standard strap gold pin with a raster of 2.54 mm, which enables connection through the connecting cables.

The relay has the following leads:

• VCC– the power of optical isolator
• GND– mass of the system
• IN1 … IN8 – controlling inputs of the relays, activated by low-state
• The jumper JD-VCC – connects the power of the relay’s coil with the optical isolator’s power
• Connector KF (ARK)– the relay’s contacts are connected by the pattern on a plate of the module.

Examples of application

• Driver of lighting
• The driver of executors
• Switch for electric devices, including motors
