The role of analog signal isolator/isolation amplifier/isolator transmitter in industrial field data acquisition: intelligent measurement and control instrumentation In many applications of automated measurement and control instrumentation, it is necessary to use an analog transmitter to isolate or convert signals that cannot be directly processed by the processor (MCU/ARM/CPU, etc.) in the system into an analog signal that can recognize reception and processing. Such as the pressure, displacement, speed, temperature, humidity, flow, sound and light, weighing and other non-electrical signals into a standard industrial analog (0-5V/4-20mA) signal. Typical application diagram: 2. The role of analog signal isolator/isolation amplifier/isolator in signal conversion and long-distance transmission: PLC/DCS application In the industrial automation control PLC/DCS system, various non-standard signals collected by sensors or transmitters of the system front stage need to be converted into standard analog signals, and sometimes the standard signals need to be (V/I, I/V). ) Convert to a signal that matches the interface of the host computer. In this case, use a signal isolation converter. For another example, the voltage signal will be attenuated in long-distance transmission, and the back-end voltage input interface is usually high-impedance and relatively susceptible to interference, and 4-20mA constant-current output will not appear these phenomena, so the need for the voltage signal ( 0-5V) is converted to current (4-20mA) to achieve long-distance transmission of signals. In some cases, the distance between the sensor or transmitter and the PLC/DCS control system is far, there is a ground potential difference circulating current interference in the non-same power supply environment, the remote line may be subjected to lightning strike induction or other signal source generated surge high voltage damage , Remote line impedance causes signal attenuation, and there is space interference in the field. Inductive coupling to the transmission line causes the output signal to be unstable. Both require signal isolator/isolation amplifier/isolator transmitter for isolation amplification, conversion transmission and interference suppression processing. Typical application block diagram of active signal isolation amplifier and passive signal isolator in PLC or DCS system: 3. Application of Analog Signal Isolator/Isolation Amplifier/Isolated Transmitter in Anti-jamming Safety Barrier: Aspects of UPS/EPS Grid Electricity Monitoring For safety and optimal monitoring of signal acquisition, the transmission of measurement and control signals always requires that the signals be electrically isolated; for example, in a dangerously high-voltage or explosion-hazardous area with different ground potentials, or at the factory measuring point and central control room Far apart, there is a high common-mode voltage between them that does not allow direct connection of the measurement signal to the central control device. In electrical measurement and control, it is often necessary to use low-voltage devices to measure and control analog voltages such as high voltage and high current. If high-voltage, high-current analog signals are not isolated, they are directly connected to A/D or other low-voltage devices. Upsampling, these high-voltage, high-current signals can easily be tapped into low-voltage circuits, jeopardizing the safety of equipment and personnel. Under these circumstances, it is absolutely necessary to electrically isolate the transmitted signals.
