Keyestudio two Channel Solid State Relay Module for arduino

The Keyestudio Two-Channel Solid State Relay Module is a contactless switching device designed for safe, reliable AC load control from an Arduino or other microcontroller. It is ideal for students, educators, and hobbyists looking to build home automation systems, robotics projects, or interactive installations.

Low-level trigger control

This two-channel module is active at a low level, meaning the relay turns on when the input control signal is between 0V and 1.5V. When the input control signal is at a high level of 3V to 5V, the relay remains off.

Reliable contactless switching

Composed entirely of solid-state electronic components, this relay offers superior reliability compared to traditional electromagnetic relays. It features non-contact operation, a long service life, fast switching speeds, and minimal outside interference.

Low power consumption

Operating at 5V DC, each channel draws 0mA of static current and 12.5mA of working current. The trigger current is a low 2mA, making it highly efficient for microcontroller-driven setups.

AC output specifications

The module features output ports rated for AC 100V at 2A. This allows you to safely switch low-power AC mains appliances and devices in your custom automation projects.
