Description

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

Connecting

For proper operation, connect the power of the relay’s coil and the digital control signal. Leads are the standard strap goldpin with pitch of 2.54 mm, which enables connection with the connecting cables.

The relay has the following leads

• 5V, DC+– power of optoisolation
• GND,DC-in– weight of the system
• IN1 … IN16– inputs controlling the relays activated by low state
• Connector KF (ARK)– the relay’s contacts are connected in accordance with the pattern on the board of the module.

Examples of application

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