SONGLE SRD-05VDC-SL-C User Manual

2 CHANNEL 5V 10A RELAY MODULE
Description
The relay module is an electrically operated switch that allows you to turn on or
off a circuit using voltage and/or current much higher than a microcontroller could
handle. There is no connection between the low voltage circuit operated by the
microcontroller and the high power circuit. The relay protects each circuit from each
other.
The each channel in the module has three connections named NC, COM, and
NO. Depending on the input signal trigger mode, the jumper cap can be placed at high
