general description:
    Jie Sheng Technology JSD OI 4-20mA-P series isolation amplifier is a two-wire 4 ~ 20mA current isolation conditioner module, and the isolation conditioner module belongs JSD MI 4 ~ 20mA series isolation amplifiers, But this product uses optical isolation technology，its anti-jamming capability  is more Stronger  than magnetic isolation technology. The isolation conditioner 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, so that the isolation conditioner IC's input voltage reaches the wide range (7.5 ~ 32V), to meet the user does not need an external power supply to realize long-distance signal, lossless transmission. The isolation conditioner IC output is design for 24VDC and sampling resistor (or load resistance) in series with the Sampling resistor (or load resistance) in series with the two-wire power supply circuit .with the current popular analog input interface board (PC), PLC, DCS, PC or other Instrumentations analog input port to match. Internal ceramic substrates, printed resistor technology and new isolation technologies make the products’ High isolation voltage(3000VDC)and wide industrial temperature, Our products meet Industrial grade environmental requirements, can work In humidity, vibration, harsh environments.
    JSD OI 4-20mA-P series isolation amplifier has PCB board soldering and standard DIN 35mm rail Slot mounting two methods　of　installation， rail mounting can be achieved signal Single-input single-output , Dual Input Dual Output, Three input and three output and so on.users just need to In accordance with the product manual wiring      
    JSD OI 4-20mA-P product very easy to use, just add a 50KΩ multi-turn potentiometer adjustment, you can achieve two-wire 4-20mA signal isolation, transmission and transformation functions, and to achieve signal long without distortion. The product simplifies the user's design, greatly improves the PCB board space utilization.
