Weidmüller UR20-4AI-RTD-DIAG / Lenze W540-C-2E-012 — 4-channel RTD analogue input module, resistance temperature detector, 16-bit resolution, individual channel diagnosis, 50/60 Hz suppression, PUSH IN, IP20, u-remote system, order no. 1315700000. A 4-channel temperature input module for the u-remote system, the module detects cable breaks and over/under-range values via individual channel diagnosis. Automatic 50 Hz to 60 Hz interference suppression and an adjustable conversion time of 36 to 240 ms are included. Sensors connect via 2-wire, 3-wire or 4-wire PUSH IN terminals to support a wide range of RTD wiring configurations. The module electronics supply connected sensors from the input current path (UIN). Compatible with all u-remote fieldbus head stations.
Available in stock — ships within 3 days after payment.

Applications
- Multi-type RTD temperature measurement in machine and plant engineering — a single module accepts all common Pt, Ni and Cu resistance temperature detector types as well as fixed resistance inputs from 40 Ω to 4 kΩ across a measurement range of –200°C to +850°C, eliminating the need for separate modules for different RTD families in mixed-sensor installations such as motor windings, HVAC systems, food processing equipment and pharmaceutical processes
- High-accuracy temperature acquisition with 2-, 3- and 4-wire lead compensation — 16-bit resolution and 0.2% FSR accuracy for Pt sensors are combined with selectable 2-wire, 3-wire and 4-wire connection modes, allowing lead resistance errors to be fully compensated in 3- and 4-wire configurations for precise absolute temperature measurement over long cable runs
- Cable break and out-of-range detection via individual channel diagnosis — each channel independently monitors sensor integrity and measurement limits, providing 20 bytes of diagnostic data that enable rapid fault localisation down to the channel level without interrupting other channels, supporting high-availability process monitoring applications
- Suppression of mains interference in AC-powered installations — automatic 50 Hz to 60 Hz interference suppression eliminates the dominant AC noise source from RTD signal paths, ensuring stable and accurate temperature readings even when sensor wiring runs close to power cables, frequency inverters or switchgear in industrial cabinets
- Hazardous area and marine temperature monitoring — ATEX, IECEx, ClassNK, ABS and DNV certifications alongside reverse polarity protection make the module suitable for certified RTD temperature acquisition in offshore, marine and Ex-zone environments within mixed u-remote I/O stations compatible with PROFINET, EtherCAT, PROFIBUS, Modbus/TCP, EtherNet/IP and other supported fieldbus protocols
