产品说明:
din导轨信号隔离变送采用iso-a-p-o或iso-u-p-o系列集成模块,pcb板上安装的,用来调节或校正零点精度和输出精度,是一种将信号隔离放大、转换成按线性比例输出的din35导轨安装型产品。产品内部包括输入信号干扰抑制滤波电路,两组隔离转换,信号调制电路,信号隔离电路和输出解调滤波电路。输入及输出侧宽爬电距离及内部隔离措施使该系列产品可以实现信号输入/输出/辅助相互之间 3kvdc 全隔离。全隔离型产品,辅助也隔离,所以必须单独供电。输入电源不能和辅助电源共用,输入,电源,输出,三者地线允许任意两者共地,敬请注意。
iso系列封装有pcb板焊接模块和din导轨卡槽固定两种安装方式,隔离一般都用在用电环境复杂的工业现场,为防止现场环境对产品出现各种干扰或损坏,对于din 35导轨安装的产品,这些保护电路都以安置据现场在产品中,用户可以直接使用(出厂已经校正)。对于ic封装的产品,由于受到尺寸空间的制约而无法载入保护电路。所以,请用户根使用环境对ic封装产品的信号输入、输出、辅助电源加装保护电路。
