Introduction:

SunYuan ISOS 4-20mA-E is one of the smallest size (SIP 7Pin) low cost passive 2-wire 4-20mA signal isolated conditioner IC. The conditioner modules can convert active 4-20mA current signal into isolated passive controlling signal to control the two-wire powered (explosion-prevention method) 4-20mA current loop. The module achieves the matching between sensor signals acquisition and active load from analog input terminal, which effectively solves problems on the conflict between the active 4-20mA current signal and power supply of two-wire current loop input end.

ISO 4-20mA-E series module employed high-efficiency stealing electricity technology which makes the IC can operate without independent power supply. And the two-wire loop powered output method used which largely reduces the costs for customers in installation. Inside the IC, there are current signal modulation circuit, magnetoelectric isolation transform circuit and signal reduction demodulation circuit,etc. The low input equivalent resistance makes the voltage value of the current signal from the sensor output loop arrive at 5~32VDC to realize the long-distance, non-distortion transmission of signals without external power supply.

The output of ISO4-20mA-E is designed on the basis of the two-wire powered loop circuit of the 24VDC and 2-wire current loop, the current loop is connected with sampling resistance (two-wire meter) in parallel, the output also matches well with the analog input terminals of the industrial equipment like analog input interface board (host machine), PLC, DCS, and other instruments and meters,etc. That conditioner module is convenient to use to achieve the isolation, transmission and acquisition of two-wire 4-20mA signal by add an external 10K© multi-turn potentiometer to do adjustment and meets the requirements that operating in industrial field wide temperature, humidity, vibration, etc adverse operation conditions. The signal conditioner has two types of package, small size PCB-mounted package, 35mm DIN rail-mounted package. The 35mm DIN rail mounted products can be 1-input 1-output, 2-input 2-output, 3-input 3 output and 16-channel isolation, etc
