B&R X20DIF371 Digital Input Module 

Product Description

The B&R X20DIF371 is a 16-channel digital input (DI) module designed for the X20 I/O system, providing 24V DC sink-type inputs for industrial automation applications. It features single-wire connection, configurable software filters, and high noise immunity, making it ideal for interfacing with sensors, switches, and other digital field devices in harsh environments .

Key Features & Advantages

1. High-Density Input Configuration

   • 16 digital inputs (24V DC, EN 61131-2 Type 1 compliant), supporting sink-type wiring .

   • Input filtering: Hardware filter (≤100 µs) and software-configurable filter (0–25 ms adjustable in 0.2 ms steps) to suppress signal noise .

2. Robust Industrial Design

   • 500V isolation between channels and backplane for EMI protection .

   • Wide voltage range: 20.4–28.8V DC (15%–20% tolerance) with 8.9 kΩ input resistance .

   • IP20 protection and operating temperature range: -25°C to +60°C (horizontal) / -25°C to +50°C (vertical) .

3. Diagnostics & Safety

   • LED status indicators per channel for real-time monitoring of input states and module health .

   • Certifications: CE, UKCA, ATEX Zone 2, UL, DNV, and more for hazardous environments .

4. Easy Integration

   • Hot-swappable in compatible X20 systems for maintenance without downtime .

   • Requires X20TB1F terminal block and X20BM11 bus module (sold separately) .

Technical Specifications

Applications

• Factory automation: Conveyor control, limit switch monitoring .

• Process control: Safety interlock systems in hazardous areas (ATEX Zone 2).

Installation Notes

• Wiring: Use shielded cables for noise-sensitive applications .

• Mounting: Ensure proper alignment with X20 base modules (e.g., X20BM11) .
