    Product introduction

    ZDK981 high-precision two-wire signal isolator receives various current and voltage signals on site, transmits them in isolation, and outputs 4~20mA current signals.This isolator is a two-wire loop power supply method, and the input loop and the output loop are completely electromagnetic isolated.Mainly used for loop-powered DCS and PLC systems, this isolator is made of ABS flame-resistant resin chassis material, which is small in size and compact in structure, and the thickness of the chassis is only 6.2mm.The modular watch core design has low power consumption and does not require zero-point and full-degree potentiometer adjustment.Meet the relevant anti-electromagnetic interference requirements of IEC61000.
