Two-wire Passive Analog Signal Isolator|Isolation Amplifier|Isolation Transmitter New Product Introduction

Introduction: Passive, in terms of electronics, it means that the circuit can work when there is a signal without a power supply. Usually, devices that can work without a power supply are called passive devices. The commonly used passive components in circuits are mainly diodes and resistors. , Inductance and capacitance components. The devices in the circuit that require an external auxiliary power supply to work normally are called active devices. Active devices are generally used to isolate and amplify signals, convert and transmit, and so on. Commonly used active devices are transistors, power amplifiers, signal transmitters, isolation amplifiers, field effect transistors, thyristors and other devices. According to the current industrial Internet's matching needs of various sensors, transmitters and PLC, DCS systems in the industrial field, Shunyuan Technology has launched a series of new products of low-cost, small-volume passive (no external auxiliary power supply) analog signal isolators , Provided to sensor and instrument manufacturers and industrial Internet system integration design engineers to choose. The following recommend several new two-wire 4-20mA output passive analog signal isolation transmitter optional technical solutions, for manufacturers and industrial Internet system integration engineers on-site application reference.
