Time relay delay range is generally how much
The current time relay time adjustment can be wide, according to the need to choose a different adjustment range, from milliseconds to seconds, to minutes, to hours, can be selected.
Usually: 0.1S ~ 9.9S and 1S ~ 60S, of course, to a few hours.
Time relay delay principle:
When adding or removing the input signal, the output part of the delay or time limit to the specified time to close or disconnect the relay line is the time relay relay.
When the coil is coupled with a signal, the time delay relay is called the electromagnetic time relay by slowing the magnetic field of the electromagnet. The time relay constituted by the electronic delay line composed of discrete components or the time consisting of the solid delay line Relay called electronic time relay; by electronic or solid delay line and electromagnetic relay combination of time relay called hybrid time relay. Their role is the same principle, that is, in the time relay coil to join or disconnect the power, after a given time after the action, to control the main line of the connected and disconnected.
1, air damping time relay, also known as the airbag type time relay, it is based on the resistance of air compression to delay, and its structure is simple, cheap, long delay range (0.4 ~ 180s), but the delay precision Low degree
2, electromagnetic time relay delay time is short (0.3 ~ 1.6s), but it is relatively simple structure, usually used in power-off delay occasions and DC circuit.
3, the principle of electric time relay and watch is similar, it is driven by the internal motor to slow down the gear and get the delay. This relay delay high precision, wide delay range (0.4 ~ 72h), but the structure is more complex, the price is very expensive.
Air damping is generally adjustable between 1S-60S, the transistor can be adjusted to 60 minutes or even longer.
