Weidmüller UR20-4AI-UI-DIF-16-DIAG / Lenze W540-C-2E-008 — 4-channel analogue input module, differential input, current/voltage, 16-bit resolution, diagnostics, PUSH IN, IP20, u-remote system, order no. 1993880000. A 4-channel differential analogue input module for the u-remote system. The differential input topology with a common mode range of ±30 V effectively suppresses interference signals in noisy industrial environments. Each channel achieves 16-bit resolution with an accuracy of 0.1% FSR and a conversion time of 1 ms. Both module and individual channel diagnosis are supported. Sensors connect via 2-wire, 3-wire or 4-wire PUSH IN terminals accepting conductors from 0.14 mm² to 1.5 mm². The module electronics supply connected sensors from the input current path (UIN). Compatible with all u-remote fieldbus head stations.

Applications
- Noise-immune analogue signal acquisition in electrically demanding environments — the differential input topology with a common mode range of ±30 V effectively rejects common mode interference from variable frequency drives, power cables and other noise sources running in parallel with signal wiring, making this module particularly well-suited to machine and plant installations where long cable runs or high electromagnetic interference are present
- High-accuracy multi-range process measurement with per-channel diagnostics — 16-bit resolution, 0.1% FSR accuracy and a 1 ms conversion time are combined with individual channel diagnosis capability, enabling rapid fault localisation down to the single-channel level in critical analogue measurement loops across voltage and current signal types within a single compact module
- Flexible sensor wiring with 2-wire, 3-wire and 4-wire connections — PUSH IN terminals accept conductors from 0.14 mm² to 1.5 mm² without tools, supporting a wide range of transducer and transmitter wiring configurations and reducing commissioning time in decentralised I/O architectures where mixed sensor types are used on the same module
- Mixed I/O stations across all u-remote fieldbus platforms — with only 8 mA system bus current consumption and compatibility with all u-remote fieldbus head stations including PROFINET, EtherCAT, PROFIBUS, Modbus/TCP, EtherNet/IP and CC-Link IE TSN, the module integrates efficiently alongside digital and other analogue modules in shared u-remote stations
- Hazardous area and marine installations — ATEX, IECEx, ClassNK, ABS and DNV certifications alongside short-circuit-proof sensor supply and reverse polarity protection make this module suitable for certified decentralised analogue input stations in offshore, marine and Ex-zone environments within the u-remote platform
