Weidmüller UR20-16DI-P | u-remote 16-Channel 24V DC Digital Input Module, Sink/Source, P-Fit
Weidmüller UR20-16DI-P u-remote digital input module — 16 × 24 V DC inputs (Type 1/3, sink/source), 10 μs response time, pluggable spring terminals, P-coding. Fits UR20 couplers (PROFIBUS, EtherCAT, PROFINET, EtherNet/IP, Modbus TCP).
Product Overview
The Weidmüller UR20-16DI-P is a 16-channel digital input module for the u-remote (UR20) I/O system, designed to acquire 24 V DC binary signals from sensors, switches, or dry contacts. All 16 inputs are Type 1 / Type 3 compliant (IEC 61131-2) and accept sink (NPN) or source (PNP) wiring — the module detects the active state regardless of polarity to common 0 V or +24 V. Each channel has an individual status LED, and the module features a diagnostic LED (RUN/ERR). It connects to the u-remote backplane via the P-coded (P = Process data) system bus connector and uses plug-in spring-cage terminals (PUSH IN) for field wiring. Compatible with all UR20 fieldbus couplers (PROFINET, EtherCAT, EtherNet/IP, PROFIBUS DP-V1, Modbus TCP, CANopen, CC-Link).

Key Features
-
16 DI in 12.3 mm Width: Highest density in the u-remote family — minimizes panel space per I/O point.
-
Sink/Source (NPN/PNP) Universal Inputs: No need to stock separate sinking or sourcing modules — one part covers both sensor types.
-
Pluggable Terminal Block: Pre-wire field cables off-panel; snap module in/out for maintenance without disturbing wiring.
-
Fast Hardware Response (≤10 μs): Suitable for high-speed counting or fast event capture when used with high-speed DI modules (note: this is std. DI — for HSC use UR20-4DI-HS-P).
-
Diagnostics via LED + Coupler: Channel-level and module-error LEDs plus diagnostic telegrams to the PLC/master.
Typical Applications
-
Machine Control Cabinets: Reading limit switches, pushbuttons, light curtains, and prox sensors on packaging / converting / assembly lines.
-
Process Skids: Distributed DI acquisition via PROFINET/EtherNet/IP coupler in modular process units.
-
Retrofit / Expansion: Adding 16 digital inputs to existing UR20 station — no re-wiring of adjacent modules.
-
OEM Panel Build: Compact footprint with pluggable terminals simplifies FAT and field commissioning.
