3、two-wire  passive 4-20mA isolation amplifier conditioning module   Model : JSD I 4-20mA-P
Jie Shengda Technology JSD OI 4-20mA-P isolation amplifier is a two-wire 4-20mA current isolation conditioner module, which using optical coupling technology ,its anti-jamming capability  is more stronger  than magnetic isolation technology .The isolator IC internal has current signal modulation and demodulation circuit, coupled converter circuits and so on. The isolation conditioner IC's input voltage reaches the wide range (7.5-32V) by small input equivalent resistance to meet the user does not need an external power supply to realize signal long-distance transmission without distortion. The isolation conditioner IC output is design for two-wire power supply loop, matching with the current popular analog input interface  (PC), PLC, DCS or other instrument analog input port. Internal ceramic substrates, printed resistor technology and new isolation technologies make the products’High isolation voltage （3000VDC）and wide industrial temperature, suitable for using Humidity , vibration, harsh environment to meet the requirements of industrial environments.
JSD OI 4-20mA-P product very easy to use, just add a 50KΩ multi-turn potentiometer ADJ correction, you can achieve two-wire 4-20mA signal isolation, transmission and transformation , it is widely used in analog signal data isolation、acquisition，industrial field signal isolation ,long-distance transmission without distortion ,analog signal ground interference suppression and other industrial field.
