Control high-power devices safely with the Grove 3V relay module. Handles 5A at 250VAC, compatible with Arduino & Raspberry Pi via digital Grove interface.
The Grove 3V Relay is a robust and compact relay module designed for seamless integration into a wide array of electronic projects. It is engineered to handle significant power loads, making it an ideal component for controlling mains-powered devices safely from low-voltage microcontroller circuits. This relay can switch currents of up to 5A at 250VAC continuously, ensuring reliable performance for extended periods. Its peak capability reaches 250V at 10A, providing a solid safety margin for demanding applications.
When the relay coil is energised and the switch is activated, a clear visual indication is provided by a built-in LED that lights up. This allows for easy status monitoring at a glance. The module operates efficiently on a low voltage supply of 3.3V to 5V, drawing a modest 100mA input current, making it perfectly compatible with popular development boards like Arduino and Raspberry Pi via its convenient digital interface and standard Grove connector.
The relay boasts excellent electrical characteristics, including a low contact resistance of 50mOhm at 6VDC 1A and high insulation resistance of 100MOhm. It offers swift switching performance with a maximum operate time of 10ms and a maximum release time of 5ms, enabling responsive control in time-sensitive circuits.
Supplied as a complete, ready-to-use unit, it includes the relay module itself and a user guide to facilitate quick setup and integration. Its compact dimensions of 42mm x 24mm x 18.5mm allow it to fit neatly into project enclosures and prototypes without occupying excessive space.
