产品介绍

适用于交流50Hz,电压至380V的电路中,通常用在自动或半自动控制系统中,按预定时间使被控制元件动作。

符合JB/T54302标准。

一些常见的型号有:JS7-1A,JS7-2A JS7-3A JS7-4A

使用说明

根据用户使用需要,可调节进气孔通道的大小来得到不同的延时时间。即用螺丝刀旋转铭牌中心之螺帽,往右旋得到的延时时间较短,反之则延时时间就长。

该空气式时间继电器额定电压380V,约定发热电流3A,额定控制容量100VA。

继电器按其所具有延时的与不延时的触头的组成可分为如表所列4种型式:

型号
延时触头的数量
不延时触头的数量
重量KG
线圈通电后延时
线圈断电后延时

每种型号的继电器尚可分类如下:

1.按延时范围可分0.4~60(s)和0.4~180(s)二种。

2.按吸引线圈的额定频率及电压可分为:交流50Hz、24、36、110、127、220、380(A)六种。继电器使用的环境温度为+40℃~0℃当施于继电器的线圈的电压为额定值的85%~110%时,继电器能可靠工作。继电器延时时间的连续动作重复误差≤15%。继电器允许用于操作频率不大于600次/h和负载因数为40%的反复短时工作制及连续工作制。

订货时,需指明继电器的完整型号、名称、延时范围及其吸引线圈的频率和电压。举例如下:

JS7-2A普通型空气式时间继电器,延时范围0.4~60S,50Hz,220V。
