SunYuan SIP12 Pin current loop isolated module: ISO 4-20mA module is a kind of single-chip two-wire isolated interface IC chip. 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 IC module achieve wide range input voltage (8.5~28VDC) to realize the long distance, non-distortion transmission of signals without external power supply. By adopting SMD technological structure and new isolation technology, the modules posses the features: 3KVDC isolation between signal input and output (total isolation type), and operates in normal in abominable industrial conditions like wide temperature, humidity and vibration.
