How Does a 2NO 2NC Relay Module Work?

The 2NO 2NC relay module is a tiny opamp operated electrical device. It is has four channels, two Normally Open (NO) and two Normally Closed(NO), which let you switch devices on or off for example. This versatile module is used in different environments, such as industrial, commercial and domestic like.

How the Module Works

The 2NO 2NC relay module does not have a lot of functions but very practical. The relay mechanism makes it so the output changes between NO and NC states when they are commanded by an electrical signal. A multi contact electrical relay is a type of an electrically operated switch that has in form of 80 to 3000 ohms widely hills its operating coil (solenoids) between switching state if possible allows for using either electromagnet the mechanical motion element/base, before which permits multiple and then re application redundant associated across radiation contacts. Architectural knowledge of the NO and NC channels is important to use module in other scenarios.
