Two-wire passive 4~20mA isolation amplifier conditioning module General Description:
Jie Shengda 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,it has better anti-jamming capability 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 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 long-distance signal, lossless transmission. The isolation conditioner IC output is design for 24VDC sampling resistor (or load resistance) in series with the sampling resistor (or load resistance) in series with the two-wire power supply circuit. to match with the current popular analog input interface board (PC), PLC, DCS, PC or other Instrumentations analog input port. its internal ceramic substrates, printed resistor technology and new isolation technologies achieve the products’ high isolation voltage (3000VDC)and wide industrial temperature range, can work in humidity, vibration, harsh environment, to meet the requirements of industrial environments.

JSD OI 4-20mA-P series isolation amplifiers have PCB board soldering and standard DIN 35mm rail slot fixed installation of two rail mounting ,can be achieved 1-input-1-output,2-input-2-output,3-input-3-output,4-input-4-output,the user simply by wiring can be used.

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 and long-distance transmission without distortion.The product simplifies the user's design, greatly improves the PCB board space utilization.
