4~20mA passive isolation amplifier module General Description:
Jie Shengda Technology JSD MI 4~20mA isolation amplifier is a current loop isolated module, the isolator module is two -wire isolated interface design, the front input 4~20mA, the backend output 4~20mA, and no working power supply to achieve 4~20mA standard signal with high accuracy and linearity isolation.to achieve signal long-distance transmission without distortion . Product isolation voltage is up to 3KVDC between input and output.JSD MI 4~20mAseries products very easy to use ,without any external components to achieve 4 ~ 20mA current loop isolation transmitter function.
Jie Shengda Technology JSD MI 4~20mA isolation amplifier have PCB board soldering and standard DIN 35mm rail slot fixed , rail mounting can be achieved analog signal one in one out, two in two out, three in three out,four in four out,users only need wiring can be used.
Jie Shengda Technology JSD MI 4 ~ 20mA series isolation amplifier products are easy to use, without external components can be realize industrial field signal isolation and conversion function, and to achieve signal long-distance lossless transmission. The products simplify the users’ design, greatly improving the PCB board space utilization.
