JS7-A series time relay (hereafter referred to as relay) is suitable for AC 50Hz, voltage to 380V circuit, usually used in automatic or semi-automatic control system, to make the controlled component act for a predetermined time.
This series of products mainly consists of three parts: electromagnetic system, contact and air chamber.
This series of products is to adjust the flow into the working air chamber to reach the different delay actions of the relay. The structure is simple, easy to make the power extension or power-off delay, and is not subject to various electromagnetic or high-frequency interference of the external circuit itself. The disadvantage is that it is susceptible to the external environment temperature, cleanliness, etc., and the delay precision is low, indicating that the dial of the set time is clear and easy to read.
