Generalization:
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.
