Description

This relay module is designed to control small electrical objects such as motor, pump, lamp, and other devices that require high voltage and high current to operate. The logic level of this module is negative, which means you need to feed a LOW (0V) signal to the input pin to activate the particular relay switch. Feed a HIGH (5V) signal to the input pins to deactivate the particular relay switch.

Note : To use this module with 3.3V device, unplug the jumper cap on the JD-VCC and VCC pins, power the relay using external 5V to the JD-VCC pin and GND. Connect VCC to 3.3V power from the device, IN1 and IN2 to respective I/O pin and GND to GND of device.

Be very careful when handling the relay with AC power source, mishandling can cause electrocution, short-circuits and unwanted consequences!
