Time relay
| |
Time relay is a kind of automatic switch device which uses electromagnetic principle or mechanical principle to realize delay control. A relay in which an input action signal is added (or removed) and the output circuit has to pass a specified exact time before a jump change (or contact action) occurs. An electrical element used to switch on or off a circuit with a higher voltage or current on a circuit with a lower voltage or current. At the same time, the time relay is also a use of electromagnetic principle or mechanical principle to achieve delay control control of control appliances. There are many kinds of it, such as air damping type, electric type and electronic type. |
