Weidmüller UR20-4DI-2W-230V-AC / Lenze W560-C-2E-001 — digital input module, 4-channel, 2-wire, 230 V AC, PUSH IN, IP20, u-remote system, order no. 1550070000. A 4-channel digital input module for the u-remote system, designed to receive binary control signals from AC-powered switches, sensors, and transmitters operating at mains voltage levels up to 265 V AC (VDE) or 277 V AC (UL). Each channel has its own LED status indicator, and module-level diagnosis is supported. The module's system electronics operate from the standard 24 V DC u-remote bus, providing full galvanic isolation of 500 V DC between the AC field side and the system bus. Compatible with all u-remote fieldbus head stations.
Available in stock — ships within 3 days after payment.

Applications
- Direct acquisition of mains-voltage AC switching signals in machine and plant engineering — the module accepts binary input signals from 230 V AC-powered mechanical switches, pushbuttons, cam switches, and relay contacts without requiring external signal converters or intermediate relay modules, simplifying cabinet design in installations where AC-voltage field devices are already installed
- Multi-phase AC installations — line-to-line voltages of up to 400 V are permissible between individual channels, enabling all four inputs to be connected to different phases of a three-phase supply simultaneously, which is particularly useful for monitoring multi-phase motor contactors, phase-presence detection, and mains-voltage interlocking circuits
- Mixed 24 V DC and 230 V AC I/O architectures — by integrating the module into a standard u-remote station alongside 24 V DC I/O modules, engineers can avoid separate AC input expansion units or dedicated AC PLC racks, consolidating all I/O onto a single fieldbus-connected station and reducing overall hardware count
- Replacement of legacy discrete AC input cards in modernisation projects — the module provides a direct fieldbus-connected alternative to traditional hard-wired AC relay input panels and older PLC AC input cards, enabling migration to modern decentralised I/O without rewiring existing AC field devices
- Hazardous area installations (ATEX/IECEx) and marine applications (ClassNK, ABS, DNV) requiring a certified 230 V AC digital input module within the u-remote platform, compatible with all u-remote fieldbus head stations
