♦What is time relay
Time relay is a controller whose delay function is carried out by electric circuit,widely used for time control and indication in automatic control circuit with rated AC current below 380V voltage of 220V,frequency of 50/60Hz.It could be divided into two categories by setting mode:
Turnbuttion setting mode:in the thrnbutton of time relay,namely,it is a continuons time setting through adjustable potentiometer changing resistance according to graduation on nameplate,but in consideration of reasons like linear change of potentinmeter and corrspoding delay capacitance error,the setting error between this kind of delay time setting and panel graduation indication is quite big,so that it is usually applied place where the delay requirement is not high.

♦selection and Notice
1 The user could select proper product according applied place and requirment ,such as delay precision,settinggerror,digital display,installing method,price,etc.
2 The delay range should be selected according to actual required delay value and made in agreement with maximum value and made in agreement with maximum value,especially for time relay of turnbutton(potertiometer)setting mode,and the long-term delay product can not be used for short-term delay control.
3 The input should be as short as possible for outward control signal,for place with high disturbance,it should use shielded wire and keep far away from power line and high voltage line.
4 For repeat delay,if the resting time between this two times is less than rest time,then it may cause phenomenon like delay time bias,instantaneity or non-action.
