SUNYUANSZ ISO 4-20MA-HT 2-wire passive type 4-20MA signal isolator with HART transmission function is a 4-20MA current loop with HART protocol transmission and control of intelligent sensor signal isolation integrated module.It is also a kind of passive signal isolation module with HART transmitting function with 4-20MA current signal input in the front stage and 4-20MA current signal output in the rear stage. The product adopts the unique electromagnetic isolation mode of SUNYUAN Technology and the patented technology of high-efficiency circuit power stealing invention, which effectively solves the problem of current signal isolation's dependence on the power supply, and realizes the passive transmission of HART signals and the isolation and transmission of analog signals of 4-20MA with high precision and high linearity. Module internal integration of HART digital signal isolation transmission circuit and analog 4-20MA current loop isolation transmission circuit, HART signal bidirectional transmission can support the field intelligent sensors and instrumentation equipment and control room DCS centralized system communication between the full play of digital and analog signals of the double advantage.This signal isolator with HART transmission function is a high-performance signal processing integrated circuit, which combines the advantages of analog signal isolation and HART communication bidirectional isolation technology, to achieve the industrial field sensors, transmitters, instrumentation and other output of 4-20MA signal isolation and HART signal transmission, to meet the reliable transmission of signals between the sensors and instrumentation equipment and accurate measurement and control. Accurate measurement and control.

ISO 4-20MA-HT series integrated modules have HART transmitting function and support bidirectional transmission of HART signals, which can ensure unobstructed communication between on-site HART smart meters and HART acquisition system in the control room, and give full play to the double advantages of isolated transmission of digital and analog signals. The product uses advanced digital technology and electromagnetic isolation to allow bi-directional communication of HART protocol signals while still isolating 4-20MA inputs and outputs. The internal integration process and new technology isolation measures enable the module to achieve 3KVDC isolation voltage and industrial grade wide temperature, humidity, vibration of the harsh environment requirements of the field, in the field of intelligent transmitters, industrial control intelligence, mining and medical equipment safety isolation barriers, industrial robots, chemical and nuclear power safety equipment has a wide range of applications.
