Weidmuller UR20-FBC-PN-IRT-V2 u-remote PROFINET IRT Fieldbus Coupler
Overview of the Weidmuller UR20-FBC-PN-IRT-V2 PROFINET Fieldbus Coupler
Weidmuller UR20-FBC-PN-IRT-V2 (order number 2566380000) is the head station of the Weidmüller u-remote IP20 remote I/O system for PROFINET networks. The datasheet describes it as a remote I/O fieldbus coupler for Ethernet with PROFINET IRT and RT, and it connects the controller to a row of u-remote I/O modules mounted on the same DIN rail. The u-remote concept is aimed at smaller cabinets, tool-free assembly and fast start-up, with a narrow modular sandwich design, an integrated web server and status LEDs on the channels and on each module for quick diagnosis.
Seven Star LLC supplies the Weidmuller UR20-FBC-PN-IRT-V2 on request from Muscat, together with advice on matching I/O modules. For plants in Oman and the GCC that standardise on PROFINET controllers for oil and gas skids, water treatment, power auxiliaries and manufacturing lines, a compact head station like this one is a practical way to bring field signals back to the PLC over standard Ethernet cabling.
Operating Principle of the Weidmuller UR20-FBC-PN-IRT-V2
The Weidmuller UR20-FBC-PN-IRT-V2 sits at the left end of a u-remote station and manages communication between the PROFINET network and the internal u-remote system bus, which runs at up to 48 Mbit/s. The fieldbus side offers PROFINET IRT and RT at up to 100 Mbit/s over two RJ45 plug-in connectors, so the coupler can be wired in line or ring topology. The datasheet lists MRP as the redundancy protocol, availability of PROFINET system redundancy S2, and a Fast Startup function for quick restart after power-up.
A station can contain up to 64 modules with 1024 bytes of process data, 1485 bytes of parameter data and 1485 bytes of diagnostic data. The coupler also feeds the system bus and the module power paths: the supply is 24 V DC with a tolerance of plus 20 percent and minus 15 percent, the feed current for the system is a maximum of 4 A, and each of the input and output current paths can carry up to 10 A. Typical current consumption from the system supply is 100 mA.
Design and Installation of the Weidmuller UR20-FBC-PN-IRT-V2
The housing of the Weidmuller UR20-FBC-PN-IRT-V2 is 52 mm wide, 120 mm high and 76 mm deep, weighs 247 g and mounts on a TS 35 rail. Field wiring for the power feeds uses PUSH IN connection for conductors from 0.14 to 1.5 mm2, so wiring is quick and needs no screwdriver. Configuration is done through a micro USB 2.0 interface, and the matching end brackets are included with the coupler. The enclosure meets UL 94 flammability rating V-0.
Status LEDs on the front indicate power, system fault, bus fault, maintenance and link and activity on both Ethernet ports, which lets a technician see the state of the Weidmuller UR20-FBC-PN-IRT-V2 without opening the engineering software. The integrated web server of the u-remote family supports commissioning and diagnosis from a browser.
Key Features of the Weidmuller UR20-FBC-PN-IRT-V2
These are the main points listed on the manufacturer datasheet for the Weidmuller UR20-FBC-PN-IRT-V2.

Industrial Applications in Oman and the GCC
The Weidmuller UR20-FBC-PN-IRT-V2 suits distributed I/O in water and wastewater plants, packaged pump and compressor skids, power plant auxiliaries, conveyor and packing lines, and utility buildings in Muscat, Sohar and Salalah. Placing the remote I/O close to the field devices shortens wiring runs, and the PROFINET link carries all the signals over one network cable instead of hundreds of individual conductors.
Seven Star LLC can also supply compatible control hardware such as the Siemens SIMATIC ET 200SP digital input module, the Allen-Bradley 1734-IB8 POINT I/O digital input module for comparison, and the Weidmuller Klippon Connect SAK terminal block for field wiring. Our team can advise on module selection, power feeding and panel layout around the coupler.
When planning a station, engineers normally total the current drawn by each module from the system and field supplies, check it against the feed limits listed above, and add a power feed module whenever the budget is exceeded. Keeping the station close to the sensors and valves it serves also makes loop checks and fault finding faster during commissioning and shutdowns.

Weidmüller identifies every item by a ten-digit order number, and that number is the surest way to quote. Without it, send the type printed on the part. For power supplies add input voltage and phases, output voltage and current. For terminal blocks add the conductor cross-section, color, and the end plates, cross-connections and markers you need, since accessories are specific to each series.Browse Weidmüller products by category: Electrical & Power Modules.
