Purchase now: Weidmüller UR20-FBC-PN-IRT-V2 PROFINET Coupler
Purchase now: Atlantech Drives provides you the Weidmüller 2853270000 (Model: UR20-FBC-PN-IRT-V2), the advanced **Fieldbus Coupler** for the ultra-compact **u-remote (UR20)** I/O system. This «V2» (Version 2) coupler is designed for **PROFINET IRT (Isochronous Real-Time)** networks, enabling high-speed, synchronized communication required for motion control applications. It acts as the gateway between the PROFINET master (PLC) and up to 64 local u-remote I/O modules.
Technical Specifications and Integrated Web Server
The UR20-FBC-PN-IRT-V2 features a built-in **2-port Ethernet Switch** for flexible line topology wiring. It supports transmission rates of **100 Mbit/s**. A standout feature is the integrated **Web Server**, which allows technicians to view the status of all connected inputs/outputs, force values for testing, and diagnose errors directly from a browser, independent of the PLC. The u-remote system is known for its high channel density and tool-free PUSH IN wiring.

Expert Tips: Hot Swapping
Minimize downtime. Expert Tip: The u-remote system supports **Hot Swap** of I/O modules (if configured in the PLC). This means if a digital input card fails, you can pull it out and plug in a new one without powering down the entire rack or stopping the bus coupler. The coupler automatically re-parameterizes the new module, getting the machine back online in seconds.
Frequently Asked Questions (FAQs)
Q: What is the difference between RT and IRT?
A: RT (Real-Time) is standard. IRT (Isochronous Real-Time) is synchronized with the PLC clock (jitter < 1µs), essential for controlling servo drives and high-speed packaging tasks.
Q: Does it need a separate power connector?
A: Yes, the coupler has a heavy-duty orange connector for the 24V supply, split into «Input Path» (Sensor/System) and «Output Path» (Actuators), allowing for separate safety shutdown of outputs.
