Relay Working Principle.
According to the state of the control pin, the connection or disconnection between the common – end COM, the normally – closed contact NC and the normally – open contact NO is controlled. The relay module can control whether the high level or the low level is effective through the jumper cap.

If set to be ‘high – level effective’:
When a’ high level’ is input at the ‘IN’ terminal, the normally – open contact ‘NO’ is in a connected state with the common contact ‘COM’, and the normally – closed contact ‘NC’ is in a disconnected state with the common contact ‘COM’. At this time, ‘Load 2’ is powered on and ‘Load 1’ is not powered on.
When a ‘low level’ is input at the ‘IN’ terminal, the normally – open contact ‘NO’ is in a disconnected state with the common contact ‘COM’, and the normally – closed contact ‘NC’ is in a connected state with the common contact ‘COM’. At this time, ‘Load 1’ is powered on and ‘Load 2’ is not powered on.

If set to be ‘low – level effective’:
When a ‘low level’ is input at the ‘IN’ terminal, the normally – open contact ‘NO’ is in a connected state with the common contact COM, and the normally – closed contact NC is in a disconnected state with the common contact COM. At this time, Load 2 is powered on and Load 1 is not powered on.
When a ‘high level’ is input at the ‘IN’ terminal, the normally – open contact ‘NO’ is in a disconnected state with the common contact ‘COM’, and the normally – closed contact ‘NC’ is in a connected state with the common contact ‘COM’. At this time, ‘Load 1’ is powered on and ‘Load 2’ is not powered on.
