A03B 1 Channel 5V Solid State Relay Module with Fuse | Low Level Trigger SSR Board 240V 2A

A03B 1 Channel 5V Solid State Relay Module with Fuse | Low Level Trigger SSR Board 240V 2A 

The A03B 1 Channel 5V Low Level Solid State Relay Module with Fuse is a compact electronic switching module designed for safe and reliable control of AC loads using low-voltage signals. Unlike mechanical relays, this module uses a solid state relay (SSR) which provides silent operation, faster switching, and longer life.

The module works with 3.3V–5V control voltage and supports low-level trigger input, making it suitable for Arduino, ESP8266, ESP32, Raspberry Pi, PLC, and other microcontrollers. It can switch loads up to 240V AC at 2A, allowing control of lights, heaters, small motors, and other electrical devices.
