An electrical control circuit is provided for a door operator to return a door to an open position should an object be encountered by the door while moving to a closed position. The control circuit includes circuit means and a pair of normally open contacts that are closed by engagement of ...
正反转自动循环控制电路工作过程如下。 按下正向起动按钮SB2,接触器KM1得电动作并自锁,电动机正转使工作台前进。运行到SQ2位置,撞块压下SQ2,SQ2常闭触点使KM1断电,SQ2的常开触点使KM2得电动作并自锁,电动机反转使工作台后退。工作台运动左端点撞块压下SQ1时,KM2断电,KM1又得电动作,电动机又正转使工作台前进...
9. Distance relay An actuator that functions when predetermined circuit admissibility, impedance, or reactance is exceeded. If each relay installed along the line has a time delay, depending on the impedance (distance), the relay picked up first is always the one closest to the short-circuit po...
MOS FET relay is a semiconductor relay that uses power MOS FETs in output elements. MOS FET relay consists of the following three components: 1. LED ( light-emitting diode ) chip 2. PDA ( photodiode array ) chip *Photodiode Array ( solar cell + control circuit ) ...
