 Isolated Barrier: Yibei isolated safety barrier used in the reliability of the input, output, power supply three isolation techniques, for all signals are taken to limit pressure side, limiting, anti-surge protection circuit, and electromagnetic isolation and method of combining optical isolation to ensure the safety and non-intrinsically safe side of the physical spacing between the strengthening of product reliability. In signal processing, Yibei isolated safety barrier to abandon the traditional analog signal into a frequency signal and then pass the signal through the optical coupling to the method, and using modem technology, allowing for precision, drift, interference capabilities have been greatly improved.
