Weidmüller UR20-4AI-R-HS-16-DIAG / Lenze W540-C-2E-011 — analogue input module, 4-channel, resistor/potentiometer, 16-bit resolution, individual channel diagnostics, 24 V DC, PUSH IN, IP20, u-remote system, order no. 2001670000. A 4-channel high-speed analogue input module for the u-remote system, designed for ratiometric potentiometer evaluation with an integrated 10 V DC sensor supply. The module covers a measurement range of 300 Ω to 50 kΩ and delivers 16-bit resolution with a typical conversion time of 500 µs per channel. Automatic 50/60 Hz interference suppression is included for use in electrically noisy environments. Individual channel diagnostics detect wire breaks and out-of-range values per channel, and each input supports 3-wire and 3-wire + FE sensor connections. The module electronics supply the connected sensors from the input current path (UIN). Compatible with all u-remote fieldbus head stations.

Applications
- High-speed ratiometric potentiometer position acquisition in machine automation — the module provides its own 10 V DC sensor supply, covers resistances from 300 Ω to 50 kΩ, and delivers 16-bit resolution with a conversion time of approximately 500 µs, making it suitable for fast-moving position feedback tasks such as linear slide, throttle, or joystick sensing
- Electrically noisy industrial environments where mains interference must be suppressed — automatic 50/60 Hz noise rejection protects signal integrity in control cabinets near variable-speed drives, transformers, or other switching equipment without additional filtering hardware
- Applications requiring per-channel fault detection — individual channel diagnostics actively monitor for wire breaks and out-of-range values on each input independently, enabling rapid fault localisation and reducing diagnostic time during commissioning and operation
- Flexible 3-wire and 3-wire + FE sensor topologies with short-circuit-proof inputs and an integrated sensor power supply of up to 50 mA per channel (200 mA total), eliminating the need for separate supply distribution components in the u-remote station
- Hazardous area installations (ATEX/IECEx) and marine applications requiring certified analogue input modules with ABS, ClassNK, DNV, and KR approvals
