The DIN35 series standard 35mm guide rail card holder structure is easy to install and can effectively isolate: the potential difference between signal input, signal output, power supply and earth.

    SunYuan ISO EM210 series analog signal isolation amplifier is a magneto-electrically coupled hybrid integrated circuits, the product adopts low-cost, small volume DIP standard 38Pin metal shell package, can effectively shield the field EMC spatial interference, and with the AD210 module Pin-Pin compatible. Module internal integration of multiple isolated DC/DC conversion circuit and magneto-electric coupling signal isolation circuit, so that the external only need to select a DC 5V/12V/15V/24V single power supply, you can complete the analog signal input/signal output/auxiliary power supply three-terminal isolation of the amplification and conversion technology, and support for single-ended and positive and negative bidirectional DC signal input and output. ISO EM210 comprehensive functional design, the use of non-fixed gain method, the input signal through the input side of the preamplifier (gain of 1-100) amplified into the internal modulator for modulation, non-fixed gain input amplifier is convenient for the user according to the site working conditions of the flexible configuration of the use of the user can be used through the peripheral feedback gain resistors, etc., to achieve the application of variable gain, modulated signals are transmitted through the transformer coupling to the output side of the amplifier output by the demodulation circuit demodulated amplification. The module's triple-isolation design structure allows the device to meet the signal input, signal output, and auxiliary power supply completely isolated by interrupting ground loops and leakage path measures, and suppresses common-mode voltages and noise, thus preventing degradation of the measurement accuracy and improving the accuracy and integrity of the measurement signals, making it ideal for single-channel or multi-channel signal isolation applications. ISO EM210 adopts the low-cost solution of magnetic coupling, mainly used for EMC (electromagnetic interference) without special requirements of the occasion, the internal DC-DC isolated power supply in addition to the power supply to the internal amplifier circuits, but also to the input and output terminals each outwardly to provide a set of ± 15V / ± 10mA regulated isolated power supply for two-wire sensor power distribution or to provide the input side of the preamplification, signal bias, Differential circuit, bridge circuit reference power. The products can meet the requirements of automotive grade field working environment with humidity, vibration and wide temperature range -40 ~ +125 ℃.

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.
