q6: 3rp1540-1..30与3rp1540-1..31的区别，能否替换？
a6: 3rp1540-1..31是3rp1540-1..30的升级产品，可以完全能满足3rp1540-1..30的功能，此两产品尺寸相同，除此之外3rp1540-1..31增加了两个延时时间段，由原7段时间设定改为现在的9段时间设定，并且增加了控制电压为ac/dc24-240v的产品。
q7: 带辅助电压的断电延时继电器3rp153与断电延时继电器3rp1540的区别?
a7: 如图所示3rp1540断电延时继电器只需要提供电源（a1、a2），就可实现断电延时的功能，而3rp153带辅助电压的断电延时继电器除了工作电源（b1、 a2）之外还需要提供供电电源（a1、 a2）。
