时间继电器的接线方法
Wiring method of time relay
第一、控制接线：把它看成直流继电器来考虑。3、7用来接12V控制电压；2、7用来接24V控制电压。其中的7当成直流电的负极，使用时接到零线。2接220V的火线。
First, control wiring: consider it as DC relay. 3 and 7 are used to connect the 12V control voltage; 2 and 7 are used to connect the 24V control voltage. 7 of them are the negative pole of DC, and they are connected to zero line when used. 2 line of 220V fire.
第二、工作控制：虽然控制电压接上了，但是是否起控制作用，由面板上的计时器决定。
Second, work control: Although the control voltage is connected, but whether control, decided by the timer on the panel.
第三、功能理解：就是一个开关，单刀双掷的，有一个活动点活动臂，就像常见的闸刀开关的活动刀臂一样。8是活动点，5是常闭点，继电器不动时，他们两个相连。动作时，8、6相连。
Third, understanding: is a single pole double throw switch, and a movable arm point, knife knife switch as often as the arm. The 8 is the active point, and the 5 is the normally closed point, when the relay does not move, they are connected to the two. When the action, 8, 6 connected.
第四：负载接线：电源的零线或负极接用电器的零线或负极端。电源的火线或正极接8脚，用电器的火线端或正极接6脚，5脚空闲不用。
Fourth: load wiring: the zero line or negative pole of the power supply connects the zero or negative pole of the appliance. The power line or the positive electrode is connected with 8 feet, and the 6 ends of the cathode or the positive end of the electric appliance are used, and the 5 feet are idle.
第五、工作原理：计时无效期间，8、5相连，相当于平常电灯开关断开状态。有效时，继电器动作，8、6相连，用电器得电工作，相当于平常电灯开关接通状态。
Fifth, working principle: invalid during the period, 8, 5 connected, equivalent to the ordinary light switch disconnect state. When effective, the relay action, 8, 6 connected, with electrical appliances work, equivalent to the usual light switch through the state.
