大概20-60之间。时间继电器（timerelay）是指当加入（或去掉）输入的动作信号后，其输出电路需经过规定的准确时间才产生跳跃式变化（或触头动作）的一种继电器。是一种使用在较低的电压或较小电流的电路上，用来接通或切断较高电压、较大电流的电路的电气元件。同时，时间继电器也是一种利用电磁原理或机械原理实现延时控制的控制电器。它的种类很多，有空气阻尼型、电动型和*型等。

品牌的不一样，价格也不一样，大概20-60之间。时间继电器的延时原理：当加上或除去输入信号时，输出部分需延时或限时到规定的时间才闭合或断开其被控线路的继电器就是时间继电器。当线圈加上信号后，通过减缓电磁铁的磁场变化而后的延时的时间继电器叫电磁时间继电器；由分立元件组成的*延时线路所构成的时间继电器，或由固体延时线路构成的时间继电器叫*时间继电器；由*或固体延时线路和电磁继电器组合构成的时间继电器叫混合式时间继电器。它们的作用原理都相同，就是在时间继电器线圈上加入或断开电源，经过你给定的时间后而动作，来控制主线路的接通与断开。

中发时间继电器型号依据其工作电压的高低，有6、9、12、24、36、110、220、380等不同的工作电压，使用于不同的控制电路上。时间继电器另一个区分点是它的触点（执行接通或断开被控制电路的开关），分别有常开、常闭、转换的区别，另外还有触点多少的区别，可以控制多大的工作电压及电流（即触点允许控制的功率）的区别，供不同用途选用；另外特殊触点还有带自锁（动作后即使控制电压消失，触点自己保持失去控制时的状态），带延时吸合或延时释放功能等种类，供特殊情况下使用。
