1 Channel 5V 30A Relay Module

5V 1 Channel 220V 30A Relay Module

High Current Power Control Switch Opto Isolation Low/High Trigger Motor Lamp Thermostat Pump Heater Contactor

     It is a 1 channel 5V triggered 220V 30A relay module. It is used in high current control applications. It has an opto isolation circuit. It has a high low signal trigger selection jumper. When H is selected, the relay becomes active with a 5V trigger signal. When L is selected, the relay becomes active with a 0V trigger. When the trigger input is floating, the relay is not active.

     It has a power indicator led. There is a relay status led. There are 4 mounting holes. It has terminal block sockets at the input and output to provide easy connection. 

Relay control: (Relay operation is explained in general.)

     Relays are generally used to control a device. One of the supply lines of the device is cut. One of the 2 ends formed at the cut point is connected to the COM terminal. The other is connected to the NO or NC terminal. Depending on the relay trigger signal, COM is connected to one of the other 2 ends. The NO pin initially ( open ) stays floating when there is no trigger. The NC pin is initially ( close ) short circuited with Com. When the trigger signal arrives, the switch inside the relay connects the COM pin to NO. NC remains floating. You need to select either NO or NC according to your operating need. If your system works in reverse, it will be enough to connect the cable you connected to NO or NC to the opposite terminal.
