中间继电器的作用主要是控制接触器，和一些小功率的用电器
The role of the intermediate relay is to control the contactor and some small power appliances.
说准确一点，中间继电器用于在控制电路中传递中间信号。中间继电器的结构和原理与交流接触器基本相同，与接触器的主要区别在于：接触器的主触头可以通过大电流，而中间继电器的触头只能通过小电流。所以，它只能用于控制电路中。 它一般是没有主触点的，因为过载能力比较小。所以它用的全部都是辅助触头，数量比较多.
To be accurate, the intermediate relay is used to transfer intermediate signals in the control circuit. The structure and principle of intermediate relay are basically the same as that of AC contactor. The main difference between the relay and contactor is that the main contact of the contactor can pass through a large current, while the contact of the intermediate relay can only pass through a small current. So, it can only be used in the control circuit. It is generally not the main contact, because the overload capacity is relatively small. So it uses all the auxiliary contacts, and the number is much more.
时间继电器的用途就是，执行延时指令。可利用时间继电器控制电器延时通断.
The purpose of the time relay is to ute the delay instruction. The time relay can be used to control the delay and break of the electrical apparatus.
它通常应用于各种机械、电信或电器设备中作为自动控制系统的定时元件,如在电动机的星三角启动电路中就有时间继电器
It is usually applied to various mechanical, telecommunication or electrical equipment as a timing element of the automatic control system, for example, there is a time relay in the star triangulation starting circuit of the motor.
它们大的区别就是时间控制方式,时间继电器你可以跟据你所须要的时间对电路的通断进行控制,而中间继电器不能
The biggest difference is the way of time control. Time relay can control the on-off of the circuit according to the time you need, while the intermediate relay can not.
