ProSoft PLX51-HART-4I 4-channel HART Input Gateway Module

I. Basic Information
Brand: ProSoft
Model: PLX51-HART-4I
Product Type: Independent DIN-rail type 4-channel HART analog input Ethernet gateway
Installation Method: Standard 35mm DIN-rail installation, protection grade IP20 (installation in control cabinet)
Power Supply: DC 12~28V, no-load power consumption 0.9W, maximum load 3.1W
Positioning: Convert 4-20mA + HART intelligent transmitter signals into Ethernet protocol, connect to Rockwell, Modbus, power SCADA systems

Model Interpretation
PLX51: Hardware platform of the PLX50 series independent Ethernet protocol gateway
HART: Supports HART industrial field instrument protocol
4I: 4 HART analog input channels
III. Supports three major Ethernet protocols
EtherNet/IP: Can be directly mounted on the I/O tree structure of Rockwell ControlLogix/CompactLogix, native Logix tag addressing, supports redundant controllers, multi-point HART bus (up to 7 HART instruments can be connected per channel) ProSoft Technology Inc
Modbus TCP: Module as a Modbus slave station, can be read by third-party PLCs such as Siemens, HuiChuan, Schneider etc. for HART process values and equipment diagnostic parameters
DNP3 TCP/UDP: Power industry standard protocol, compatible with power plant, water treatment SCADA dispatching systems, supports security authentication mode
Additional Compatibility: PCCC (AB-ETH), connects to old SLC500, PLC5 controllers of Rockwell

Core Parameters of 4 HART Analog Inputs
Input Signal: Standard 4~20mA loop, compatible with all HART 5/7 protocol intelligent instruments (pressure, level, temperature, flow transmitters)
Measurement Range: 0~22mA, built-in 34mA overcurrent protection
ADC Resolution: 12 bits
Measurement Accuracy: Calibrated <0.15% FS; Un-calibrated <0.30% FS
Single Channel Support: Point-to-point single instrument / multi-point bus (up to 7 HART slave devices)
Loop Fault Diagnosis: Short circuit, under-range, over-range alarm uploaded to PLC

Core Function Highlights
HART Transmission (FDT/DTM): Remote configuration and calibration of transmitters through upper HART operator station software, no on-site wiring required
Built-in Web Server: Web view of channel current, equipment status, fault log, packet capture diagnosis, online configuration of IP and channel parameters
6-channel status indicator lights on the front panel: Module operation, Ethernet link, 4-channel fault / operation status
Support hot swapping, configuration software: PLX50 Configuration Utility
Single Channel Can Collect 4-20mA Real-time Process Value, Also Read HART Device Tag Number, Range, Temperature, Fault Code, Cumulative Quantity and Other Additional Parameters ProSoft Technology Inc

Typical Application Scenarios
DCS systems in petroleum, chemical, power plants, water treatment, connect 4-20mA instruments to achieve intelligent HART data transmission
Rockwell Logix control system connects multiple intelligent transmitters, replacing rack-mounted MVI56-HART module
Power plant station SCADA system collects on-site HART instrument data through DNP3 protocol Intelligent upgrade of old analog instruments, remote equipment operation and maintenance, fault prediction. ProSoft PLX51-HART-4I 4-channel HART input gateway module.
