5、Two-wire passive 4-20mA to voltage signal isolation converter:
      ISO 4-20mA-O Series Two-Wire Passive I/V Conversion Isolation Transmitter IC 

     
         
 ISO 4-20mA-O is the smallest in the industry (12 pin single in line SIP12 Pin) low cost two wire passive current loop 4-20mA to voltage signal isolation converter IC developed by SunYuan. It can make the input active 4-20mA current signal into a voltage signal output. this IC use two-wire input loop power supply mode, and has unique patented technology for high-efficiency signal loop stealing. It does not require external working power supply, which greatly simplifies the user's design process and reduces the cost of field wiring. The internal of module including a current signal modulation and demodulation circuit, a signal coupling isolation conversion circuit, a power supply inverter circuit, a subtraction circuit, a buffer processing output circuit, and so on . The small input equivalent resistance allows the IC to acquire current signals from the sensor signal output loop and achieve a voltage drop of ≤10V when inputting a 20mA signal. and meet the needs of users without the need for external auxiliary power to achieve long-distance, distortion-free transmission of signals. ISO 4-20mA-O is often used for the isolation of 4-20mA current to voltage signals, eliminating the need for an external power supply to make wiring simpler, lower power consumption, lower self-heat (basically no temperature rise), and high reliability. The biggest feature of the item is that it does not require an external auxiliary power supply. It contains a subtraction circuit and an amplifier buffer output circuit. These circuits bring simple and reliable advantages and also have limitations in use. It is isolated and transmitted for the sensor and PLC output 4-20 mA signal. From another definition, it is the transmission of electric power, so there must be power loss inside. This loss is expressed in the product of the input current value and its own input voltage drop. In this case, the 4-20 mA signal source must have the ability to drive a 500 Ω load in order for the two-wire passive 4-20 mA turn to voltage signal isolation converter to make ISO 4-20 mA-O works well. At present, from the practical application experience of industrial sites, most of the field instruments and sensors, PLC\DCS, etc. can meet the 4-20mA signal output and have the ability to drive 500Ω load. In applications of industrial field, some use only one I/V conversion sampling resistor to convert the input current signal into a voltage signal. Although this circuit is simple, it is not practical. Firstly, when the actual meaning is zero signal, there will be a zero current flowing through the sampling resistor. If the input current is converted to the maximum 5V voltage according to the 4~20mA input analysis, the zero point happens to be 1V. When this 1V is sufficient in the MCU resources, it can be subtracted by the microcontroller software. But in this case, the useful voltage will leave 5-1=4VDC instead of 5VDC. Because of  the maximum input voltage of the microcontroller A/D is the supply voltage of the microcontroller, this voltage is usually 5 VDC. Therefore, it is troublesome to deal with such a simple input conversion circuit, and in order to achieve the number of A/D conversion bits, the cost of the chip is increased. A simple way to solve the above problem is to configure a subtraction and buffer processing circuit composed of an operational amplifier before the input of the single-chip microcomputer. Increasing this level of circuit can make the processing of the zero point more convenient, without consuming the internal resources of the single-chip microcomputer, especially the single-chip microcomputer. When the A/D interface is used to accept such a zero signal and the input is not zero voltage value, the resources of the A/D conversion bit number can be all applied to the useful signal.
