Product Description

HART Transmissive 4-20mA Two-wire Passive Isolation Distributor

  The HART transmissive 4-20mA two-wire passive isolation distributor is a smart sensor module specially designed for industrial instrumentation with HART protocol transmission and control. The working principle is to supply power to the front stage two-wire intelligent devices through the back stage feeder, and at the same time receive the two-wire 4~20mA current signals from the intelligent devices, and output the 4~20mA standard signals through the isolation and filtering. Module internal integration of HART digital signal isolation transmission circuit and analog 4-20mA current loop isolation distribution circuit, HART signal bi-directional transmission to support the field of
intelligent sensors and instrumentation equipment and control room DCS centralized system of communication between the full play of digital and analog signals of the double advantage. This signal isolation distributor with HART transmission function is a kind of high-performance signal processing equipment, which combines the advantages of signal isolation distribution and HART communication technology, and can realize the isolation and distribution of two-wire sensors, transmitters, instruments, etc. in the industrial field, as well as the reliable transmission of signals and accurate measurement and control. ISO 4-20mA-FHT module is mainly used for industrial field intelligent sensor 4-20mA signal isolation and distribution and HART signal transmission, the work can be for the front end of the two-wire device distribution 16V ~ 21VDC, convenient for some two-wire sensor signal measurement and remote transmission function. Module output is designed for 24VDC and sampling resistor (load resistor) in series with the two-wire power supply circuit (on-site explosion-proof function) to match the current commonly used analog input interface boards (host computer), PLC, DCS or other instrumentation equipment analog input ports in the industrial field, the internal integration process and new technology isolation measures to enable the module to achieve 3KVDC isolation voltage and industrial-grade wide temperature humidity and vibration requirements of harsh environments in the field. The internal integration process and new technology isolation measures enable the module to achieve 3KVDC insulation voltage and industrial grade wide temperature, humidity, vibration of the harsh environment requirements, in the field of intelligent transmitters, industrial control intelligence, mining and medical equipment safety barrier, industrial robots, chemical and nuclear power safety equipment has a wide range of applications.
