Keyestudio Single One Channel Solid State Relay Module FOR arduino

The Keyestudio Single One Channel Solid State Relay Module is a reliable, contactless switching solution designed for Arduino projects. It is ideal for students, makers, and hobbyists looking to control high-voltage AC loads safely without the noise or wear of mechanical relays. This compact module offers fast switching speeds and a long service life for your automation projects.

Low level trigger control

This module is active at a low level, meaning an input control signal of 0V to 1.5V turns the relay on. Conversely, a high-level input signal of 3V to 5V turns the relay off, allowing for straightforward integration with microcontroller outputs.

Contactless solid state design

Built entirely from solid-state electronic components, this device operates without any physical contacts. This contactless design ensures higher reliability, faster switching speeds, and significantly reduced outside interference compared to traditional electromagnetic relays.

Extended operational lifespan

Because there are no moving mechanical parts to wear out over time, this solid-state relay offers an exceptionally long service life. This makes it an excellent choice for projects requiring continuous or high-frequency switching.

Reliable AC load switching

Designed to safely interface low-power microcontrollers with AC mains loads, the output port supports up to AC 100V at 2A. This allows hobbyists and makers to safely control small AC appliances and lighting.

Key electrical specifications

The module operates on a DC 5V voltage with a static current of 0mA and a working current of 12.5mA. It features a trigger voltage of 0V to 1.5V with a trigger current of 2mA, and supports an AC 100V/2A output port.
