1 Channel 5V Active Low Relay Module

1 Channel 5V Active Low Relay Board

The 5V 1-channel relay module works with a 5V to 12V TTL control signal. It is perfect for controlling home appliances and for use in microcontroller projects. the 5V relay module can handle a 220V AC load, so you can use it to control motors, LED strips, or other devices.

This single-channel relay acts like a regular switch, keeping its contacts separate from the circuit it controls. It has an LED light to show when the relay is ON and accepts input from a 3-5V microcontroller.

The output terminals connect to the relay, and theres a 2×3-pin male header for easy wiring. You can power it with an external 5V source or through the male header. The 5V relay module can handle up to 5A at 240V AC.

Note: It is important that the microcontroller shares ground with the relay board along with other control signals else it will not be able to control the relay.
