16-Channel HART Analog Input Module

16-Channel HART Analog Input Module


UWNTEK high quality UW5211 16-Channel HART Analog Input Module realizes program-controlled amplification, data conversion, fault diagnosis, digital filtering, linear correction, engineering conversion and other functions of 4~20mA analog input, and supports HART device communication and instrument equipment management AMS Function; when HART equipment communicates, it does not affect real-time data collection and processing; the hardware configuration software has the function of an instrument equipment management system, integrating the digital signals and conventional signals of each HART field device into a unified platform, allowing users to remotely view, modify, Configure field device configuration information and record all related operations to improve maintenance efficiency.

HART (Highway Addressable Remote Transducer) is an open communication protocol for high-speed addressable remote sensors. It is a communication protocol used between on-site smart instruments and control room equipment. It uses FSK frequency shift keying signals based on the Bell202 standard. The low-frequency 4~20mA analog signal is superimposed on the audio digital signal with an amplitude of 0.5mA for two-way digital communication, with a data transmission rate of 1.2Mbps. Based on the 4~20mA main variable information, other instrument measurements, process parameters, equipment configuration, calibration and diagnostic information, etc. can be transmitted, and the instrument equipment management system AMS can be implemented

UWNTEK 16-Channel HART Analog Input Module Features:

Intelligent conditioning, supports 16 channels of HART analog 4-20mA input, with high precision in the full range;

Online self-correction, automatic compensation of ambient temperature, no adjustment, no maintenance, automatic identification of disconnection;

There is complete electrical isolation between the module and the system; the PhotoMos switch switches the scanning channel, and there is complete electrical isolation between channels to keep out external interference;

HART equipment directly realizes the remote control and management function of on-site HART equipment through the UWnTek control engineering application software platform;

Equipped with a combined industrial terminal block group, the cage, cage bottom plate, terminal board and their connecting cables are eliminated to facilitate user use and maintenance;

Built-in input voting algorithm, input self-test and fault reporting mechanism, multiple redundant combinations of single and dual redundancy can be used, and redundancy solutions can be configured on a module basis.
