Promotes the pair of road 0-5V/4-20mA high integration isolation switch along the source science and technology
The ISO series isolation amplifier will be one kind the simulated signal carries on the isolation and the transformation hybrid integrated circuit according to the proportion (IC), it will divide into active (contains accessory power supply) and the passive two big kinds.

The passive IC interior contains has the electric current signal modulation demodulation electric circuit, the signal coupling isolation transfer network and so on, the very small input equivalent resistance, enables this IC the input voltage to achieve the ultra width scope (7.5 - 32V), satisfies the user not to need the external power supply to realize the signal long-distance range, the non- distorted transmission need. The internal ceramic foundation plate, the printed resistor craft and the new technical isolation measure enables the component to achieve the 3KVAC insulation voltage and the industry 级宽 temperature, is moist, the vibration scene adverse circumstance request. Outside ISO the 4-20mA series product use extremely facilitates does not need to meet any part then to realize the 4-20mA electric current link isolation or the signal as soon as enters two, two enters two and so on the transformation function.

Active IC was integrated a high isolation DC/DC power source and the high performance linear photoelectricity coupler hybrid integrated circuit on the identical chip. This chip besides for internal enlargement electric circuit power supply, but also may (signal input AND output end) provide two groups to exterior to isolate, the negative direct-current power supply and two group of 5VDC constant voltage datum source, feeds specially exterior electric circuit to expand uses, like user allocated-use circuit and so on bridge circuit, small signal pre-amplification electric circuit. This series product has width signal band width 20KHZ, may carries on the isolation to 0~±10VDC the bidirectional direct current signal or the 0~5VAC exchange signal, recuperates with the transformation. This IC volume very small, the use is extremely convenient, only must the very few exterior parts then realize the simulated signal (I/I I/V V/I V/V) to isolate and the transformation function.

Main application domain: The simulated signal data acquisition, the isolation transmits and supplies power, the industry scene signal isolation transmits and transforms, grounding interference suppression, signal long-distance non- distortion transmission, instrument measuring appliance and sensor signal isolation transformation. Power equipment and medical instrument segregation of security grid.
