7 lis 2020 · Dry Contact Definition: A dry contact is defined as a switch that controls electrical circuits without supplying the power itself, relying on an external source. Functionality: Dry contacts operate by opening and closing circuits, providing essential isolation and safety in electrical systems.

A dry contact is a simple electrical interface that does not carry voltage or current but is used to control the flow of electricity in various applications, serving as a switch or a relay. A dry contact is generally called a “dry contact closure” or ‘the potential free contact.’.
The Simple Definition. A dry contact is a contact that is isolated from a power source. This means that, once a power source is wired to a dry contact, it becomes “wetted” and is now able to send a signal to a controller.
17 maj 2020 · A dry contact, when energized, will not measure any output voltage unless a separate terminal is supplied with power, isolated from the device's own supply (industrial relay contacts are a common example). But why are there two varying standards; is one better than the other? And why is it important to understand the difference? Wet vs. Dry ...
