Similarly, it is asked, what is dry and wet contact?
Dry contact means potential free contact ane 'wet' contact means it is potentially loaded contact which is very easy for connecting direct load to the output of relay module..
Similarly, what does a dry contact mean? Dry contact. No current: A dry contact is the synonym of volt free - it is not "wetted" by a voltage source. Dry contact can refer to a secondary set of contacts of a relay circuit which does not make or break the primary current being controlled by the relay.
Considering this, how does a wet contact relay work?
Current flows through either set DVR, but in the case of a wet contact, the source that makes the contact sources through that contact to the device you want to control. With a dry contact, the source originates from the controlled device, goes through the contact, back to the device.
What is a dry contact input and output?
A dry contact or digital input is a set of switch contacts that have no other circuit or voltage wired to them. We supply 5vdc to the inputs. On open circuit there is no current. On closed circuit, there is up to 10ma of current. Furthermore, each dry contact or digital input can be programmed on an individual basis.
