Product Overview

The B&R X20DIF371 (X20 DIF 371) is a high-density digital input module tailored for the B&R X20 automation platform. This module provides 16 digital inputs rated for 24 VDC, utilizing a source circuit architecture specifically designed for 1-wire connections. Ideal for complex machine control in sectors like automotive assembly, packaging, and high-speed processing, the X20DIF371 allows for efficient, high-volume signal acquisition. By employing a software-configurable input filter, the module effectively eliminates signal bounce and electrical noise, ensuring high-fidelity data transmission to the controller and reducing the likelihood of erratic machine behavior or nuisance faults.

Technical Configuration

Designed for seamless integration with the B&R X20 system, the module requires the X20TB1F terminal block and X20BM11 bus module to facilitate its standard 12.5 mm pitch installation. The hardware supports both horizontal and vertical mounting orientations, providing flexibility in crowded control cabinet environments. Each channel features dedicated status indicators, supplemented by module-level run/error diagnostics that are accessible via both the physical LED array and the host software. The input circuitry is optimized for sink input wiring, and the system-wide programmable filter allows engineers to tune the input response time to match the specific demands of the connected field sensors.

Technical Specifications

FAQs

Is the X20DIF371 compatible with standard sink/source sensor types?

This module is specifically designed for sink input wiring. Ensure your field sensors are configured to provide the correct switching signal compatible with this module's source circuit architecture.

How do I adjust the input filter for the module?

The input filter is configured through the B&R automation software, which allows you to set the filter duration for the entire module. This is particularly useful for suppressing noise in environments with heavy electromagnetic interference.

Are the necessary mounting accessories included with the module?

No, the X20DIF371 requires the separate purchase of the X20TB1F terminal block and the X20BM11 bus module to complete the installation.

Installation and Operational Guidelines

• Environmental Derating: While the module is rated for operation up to 60 deg C in horizontal orientations, ensure that any installation above 2000 m altitude accounts for ambient temperature derating. For every 100 m above this threshold, reduce the maximum allowable ambient temperature by 0.5 deg C to maintain component longevity.
• Wiring Integrity: Given the 1-wire connection design, maintain clean signal paths to minimize crosstalk. Use shielded cables where signal runs exceed several meters, and ensure the screen is terminated according to your facility's EMC protocols to utilize the full capability of the configurable input filters.
• Cabinet Placement: When installing the module vertically, note the lower temperature limit of 50 deg C. Ensure that the cabinet cooling system directs air across the module fins without obstruction to prevent localized hot spots that could affect input timing precision.
