PARKER派克气缸GDC50-300 3/8电流I2l的方向从T2流向T1。由特性曲线可知，这时双向可控硅触发导通规律是按第二象限的特性进行的，又因为触发信号是正向的，所以把这种触发叫做“象限的正向触发”或称为I+触发方式。(2)如果主电极T2仍加正向电压，而把触发信号改为反向信号(图5b)，这时双向可控硅触发导通后，通态电流的方向仍然是从T2到T1。我们把这种触发叫做“象限的负触发”或称为I-触发方式。(3)两个主电极加上反向电压U12(图5c)，输入正向触发信号，双向可控硅导通后，通态电流从T1流向T2。双向可控硅按第三象限特性曲线工作，因此把这种触发叫做Ⅲ+触发方式。(4)两个主电极仍然加反向电压U12，输入的是反向触发信号(图5d)。

主要目标在保护暴露於不同等级之危险性的机械操作人员。中文名继电器外文名Safetyrelay组合数个继电器与电路组合而成目的要能互补彼此的异常缺陷主要目标保护暴露於不同等级之危险性目录1基本信息?定义?要求?用途2原理?电磁式?热敏干簧?固态式3使用方法基本信息编辑定义所谓“继电器”并不是“没有故障的继电器”，而是发生故障时做出有规则的动作，它具有强制导向接点结构，万一发生接点熔结现象时也能确保，这一点同一般继电器完全不同。继电器是一个回路中所必须的控制部分，它接受输入，通过内部回路的判断，确定性的输出开关信号到设备的控制回路里。简单地说，继电器都是双通道信号型，只有两个通道信号都正常时，继电器才能正常工作；
