1-Channel 5V Low Level Trigger Relay Module
Features:
LED indicator light for power on and contacting status indication;
Output terminals are the three screw terminals with blue plastic casing: the terminal in the middle for Com. the left one for NO, the right one for NC;
It can be used as a relay module for various logic control units;
Low level triggering means that when the voltage between the input terminal (IN) and ground (GND) is 0, the relay will be activated.
