Industrial Digital Input Solution – Weidmuller 1315700000 UR20-4DI-P | u-remote Series
Where This Product Is Used
The Weidmuller UR20-4DI-P (Part No. 1315700000) is a 4-channel digital input I/O module from the u-remote decentralized I/O system. It is deployed across a wide range of industrial environments where reliable, high-speed digital signal acquisition is critical:
- Automated Assembly Lines – Captures proximity sensor and limit switch signals for conveyor positioning and part detection.
- Process Plants & Chemical Facilities – Monitors valve position feedback, flow switches, and level sensors in hazardous or demanding environments.
- Machine Tool & CNC Systems – Interfaces with door interlocks, tool presence sensors, and safety switches for machine cycle control.
- Packaging & Material Handling – Reads encoder pulses and photoeye signals for product counting and sorting logic.
- Water & Wastewater Treatment – Acquires digital status signals from pumps, valves, and level switches in distributed field cabinets.
- Building Automation & HVAC – Integrates with BMS controllers to monitor damper positions, fan status, and alarm inputs.

Why Engineers Specify This Model
- Tool-Free Wiring: Push-in spring clamp terminals dramatically reduce panel wiring time versus screw terminals — critical for high-density cabinet builds.
- Modular Scalability: The u-remote system allows engineers to mix DI, DO, AI, AO, and specialty modules on a single backplane, minimizing BOM complexity.
- Fieldbus Agnostic: One hardware platform supports all major industrial protocols via interchangeable head stations — future-proofing the installation.
- Compact Footprint: Slim module width maximizes channel density per DIN rail meter, essential in space-constrained enclosures.
- Diagnostic LEDs: Per-channel status indication enables rapid fault isolation without a laptop or SCADA access.
- Wide Temperature Range: Rated to -25 °C, suitable for outdoor field cabinets and cold-storage automation.

Application-Specific FAQ
Q: Is the UR20-4DI-P compatible with SIEMENS S7-1500 via PROFINET?
A: Yes. Pair it with the UR20-FBC-PN head station and import the GSDML file into TIA Portal for seamless integration.
Q: Can this module be used in a Zone 2 hazardous area?
A: The module itself is IP20 rated for standard enclosures. When used with an ATEX-certified u-remote head station and installed in a suitable Ex e enclosure, Zone 2 / Zone 22 operation is supported.
Q: What sensor types are compatible with the PNP inputs?
A: Any PNP (sourcing) 24 V DC sensor — including inductive proximity sensors, photoelectric sensors, magnetic reed switches, and push-buttons with PNP output.
Q: How many UR20-4DI-P modules can be connected to one head station?
A: Up to 32 I/O modules (mix of DI, DO, AI, AO) per u-remote head station, subject to total current consumption limits.
Q: Is a configuration tool required for commissioning?
A: No software configuration is required for the module itself. The head station handles all fieldbus addressing. Diagnostic data is accessible via the fieldbus master.
