Weidmüller UR20-4AI-TC-DIAG / Lenze W540-C-2E-014 — 4-channel thermocouple analogue input module, 16-bit resolution, individual channel diagnosis, 50/60 Hz suppression, PUSH IN, IP20, u-remote system, order no. 1315710000. A 4-channel temperature input module for the u-remote system. With an accuracy of 0.2% FSR and 16-bit resolution, the module covers a measured temperature range from –200°C to +2315°C. Internal and external cold-junction compensation (internal accuracy ≤ 3 K) is provided, along with automatic 50 Hz to 60 Hz interference suppression. Cable break and out-of-range values are detected via individual channel diagnosis. The adjustable conversion time of 36 to 240 ms allows the module to be optimised for speed or accuracy. Sensors connect via 2-wire PUSH IN terminals. 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 thermocouple temperature measurement in machine and plant engineering — a single module accepts all common thermocouple types (J, K, T, B, N, E, R, S, L, U, C) as well as direct millivolt signals across a measurement range of –200°C to +2315°C, eliminating the need for separate modules for different thermocouple types in mixed-sensor installations such as furnaces, dryers, extruders and heat treatment systems
- High-accuracy temperature acquisition with cable break detection — 16-bit resolution, 0.2% FSR accuracy and individual channel diagnosis with cable break and over/under-range detection enable reliable, precise temperature monitoring with immediate fault notification down to the channel level, supporting preventive maintenance and process safety in critical thermal applications
- Suppression of mains interference in industrial environments — automatic 50 Hz to 60 Hz interference suppression eliminates the dominant noise source in AC-powered installations, ensuring clean thermocouple signal acquisition even when sensor cables run close to power wiring, variable frequency drives or other noise-generating equipment
- Flexible cold-junction compensation for accurate absolute temperature readings — both internal cold-junction compensation (accuracy ≤ 3 K) and external cold-junction compensation are supported, allowing the module to be configured for applications where terminal block temperature variations must be precisely compensated to achieve accurate absolute temperature measurement
- Hazardous area and marine temperature monitoring — ATEX, IECEx, ClassNK, ABS and DNV certifications alongside reverse polarity protection make this module suitable for certified thermocouple 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
