SunYuan ISO EM A4-Px-O1-HT series active type 4-20mA signal isolation amplifier with HART transmission function is a 4-20mA current loop with HART protocol transmission and control of industrial instrumentation, intelligent sensor signal isolation module.In order to ensure the normal transmission of signals, when the scene for the support of the HART protocol for intelligent meters, it is necessary to configure the signal isolator with HART transmission function, so that the intelligent transmitter access to the signal isolator, you can be in the system side of the HART hand manipulator or collector through the signal isolator and the field instrument communication, and does not have the HART function of signal isolator can not realize this requirement.Signal Isolator with HART Transmission is a high-performance signal processing device that combines the advantages of signal isolation and HART communication technology to achieve reliable transmission and accurate measurement of industrial field signals.
ISOEM A4-Px-O1-HT series integrated module has HART transmitting function, supporting 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 bidirectional communication of HART protocol signals while still isolating 4-20mA inputs and outputs.The HART pass-through function provides a channel for HART signal transmission without crosstalk, alteration, etc. of the transmitted content.Through reliable electromagnetic isolation technology, it effectively suppresses all kinds of interference signals, and at the same time eliminates the interference from on-site signal loops and ground networks to the I0 acquisition system, ensuring the accuracy of signals and the stable and safe operation of the system.
ISOEM A4-Px-O1-HT series modules are packaged in a small, standard SIP12Pin flame-retardant enclosure and resin material, with a single power supply and a set of isolated DC/DC converter power supplies and a set of magnetically coupled analog signal isolation amplifiers integrated on the same chip.The module supports input of 2-wire, 3-wire, 4-wire transmitter or current source signals, converted to standard 4-20mA current signal output by isolation, and also supports bidirectional transmission of HART digital signals.No external potentiometer element is required, free of zero and gain adjustment, omitting the need to repeatedly calibrate the zero and fullness of the tedious, which greatly simplifies the user's design and field use costs.The product internal electromagnetic isolation technology compared with the optocoupler isolation technology has a better temperature drift characteristics and linearity, auxiliary power supply single power supply and signal input, output and 3000VDC triple isolation design, so that the user site at the same time in the use of multiple modules, can be used in a single or multiple power supply.
ISOEM A4-Px-O1-HT series modules are simple and easy to use, the products have PCB board welding and standard DIN 35 rail slot fixed two kinds of mounting methods, rail-mounted products with isolated distribution output function, to provide 24VDC isolated power supply to the input side, to realize the industrial field two-wire sensors, transmitters, instruments and other isolated power distribution and signal acquisition of the reliable transmission and precise measurement and control. transmission and accurate measurement and control.DIN-rail mounted products can also realize one-in&one-out, one-in&two-out, two-in&two-out, etc. industrial field of various sensors and instrumentation or control system letter analog signal isolation, distribution, amplification conversion and distribution functions, and can meet the humidity, vibration and a wide range of temperatures (-40 ~ +85 ℃) of the industrial use of the environmental requirements.It has a wide range of applications in the fields of rail voltage monitoring, generator or motor safety operation monitoring, power transmission and distribution remote monitoring, instrumentation and sensor signal transmitting and receiving, medical equipment safety isolation barriers, industrial robotics automation control, chemical and nuclear power equipment, and so on.
