Relay delay time control / ST3P digital Time relay is when add (or remove) the action of input signal, the output circuit has been stipulated in the accurate time to produce jump change (or contact) of a relay. Is a kind of use in low voltage or current smaller circuit, used to put through or cut off the high voltage, large current of electrical components of the circuit. At the same time, the time relay is a kind of time delay control is realized by using the principle of electromagnetic or mechanical principle of electrical control. It is a lot of more phyletic, air damping type, electric type, electrical and so on.
Time relay main function is as a executive device in the simple program control, timing starts when it receives the start signal, the time after the end of its work contact to open or close the action, in order to impel the circuit of follow-up work. In general, the time delay of time relay performance is within the scope of the design can be adjusted, which is convenient to adjust the delay time length. A time relay'm afraid I can't do it alone start time closing, closed after a period of time, and then disconnect, first time after closing time disconnected, but overall, by configuring a certain amount of time relay and intermediate relay are all can be done.
1, the air damping type time relay, also known as bellows type time relay, it is based on the air compression resistance to delay, its structure is simple, cheap, wide time delay range (0.4 ~ 180 s), but the delay precision is low.
2, electromagnetic relay time delay time is short (0.3 ~ 1.6 s), but its structure is simple, usually used in delay occasions and dc power.
3, the principle of dynamic time relay like clocks and watches, it is obtained by internal motor drive gear rotation and time delay. The relay delay of high precision, wide time delay range (0.4 ~ 72 h), but the structure is more complex, the price is very expensive.
4, the transistor type time relay, also known as electronic time relay, it is to use time delay circuit for time delay. This kind of relay with high precision, small volume.
Time relay connection methods
1, control wiring to treat it as a dc relay to consider;
2, work control: although connected to the control voltage, but whether the control effect, is decided by the timer on the panel;
3, function to understand: it is a switch, single pole double throw, arm has an active point activity, like the activities of the common knife switch knife arm;
4: load connection: the power of zero or negative or move the electrical zero or negative extreme;
5, works: during the timing is invalid, equivalent to a normal light switch off state. Effective, relay action, with electrical electrical work, equivalent to ordinary electric light switch state.
