2020年11月7日 · What is a Dry Contact? A dry contact (also known as a volt free contact or potential-free contact) is defined as a contact in which power / voltage is not directly provided from the switch but is instead always being supplied by another source. Dry contacts are known as passive contacts, as no energy is applied to the contacts.

What is a Volt-Free Contact? At its core, a volt-free contact is simply an ordinary switch. Contrary to what the name might suggest, it doesn’t monitor resistance or potential in any complex manner. It’s just a basic contact that can be used to power or control other devices but a ‘free contact’ one that is free to be used to control ...

根据楼上的观点，volt free contact 的意思应该是该触点是没有电压的，也没有接地，即“dry”， 如果将其施加一定的电压（包括接地，0v），那么该触点就应该是带电的，非自由的，即“wet”

2007年8月16日 · Voltage free contact means that the contact is free to carry whichever voltage you choose to feed/supply it with. One moment you may send 5V through that contact, the next moment you may send 10V through it, the next moment 0V, the next moment 3V, etc, etc, etc. Basically, the choice of voltage to be sent through that contact at any given time ...

Volt free, potential free or dry contacts are commonly found on electronic equipment. In this video, we explain what a volt free contact is, how they operate...

2023年10月22日 · In this video I explain the zero volt contact, or you may of heard it called the volt free contact or a dry contact or a potential free contact. Whatever you...

A dry-contact or voltage-free is one where the controlling electronics have no direct contact at all typically the switch side of a relay. The idea is to be the perfect hand-over point between two electronic systems where neither party has to know about …

A dry contact, also known as a volt-free contact or a dry circuit, is an electrical circuit that does not carry any current. Instead, it is used to send a signal or control information between two devices. This type of contact is typically found in relay systems, switches, and …

A dry contact (also known as a voltage-free contact or potential-free contact) is defined as a contact in which power/voltage is not provided directly from a switch, but always through some other source. Dry contacts are referred to as passive contacts because they receive no energy.

What is a dry contact? A dry contact, also known as a volt-free or potential-free contact, is an electrical switch that does not carry any voltage or current. This type of contact is commonly used in a variety of applications where electrical isolation is required, preventing any interference or potential damage.
