B&R X67DM1321 Digital Mixed I/O Module

Parameters

Core Advantages

IP67 Protection for Cabinet-Free Installation
The X67DM1321 features a fully sealed IP67-rated housing with M8 and M12 connections, enabling direct mounting on machinery or production lines without the need for protective enclosures. This reduces control cabinet footprint and shortens field wiring distances .

Flexible Channel Configuration
All 8 digital channels are software-configurable as either inputs or outputs, providing maximum flexibility for varying application requirements. The input channels offer additional functions including event counting and gate measurement, eliminating the need for separate specialized modules .

Advanced Input Functions
Two event counters support up to 50 kHz input frequency, ideal for high-speed counting applications. One gate measurement channel is available for pulse width and timing measurements. The configurable input filter allows software adjustment from 0 to 25 ms in 0.2 ms intervals, helping to suppress noise in demanding environments .

Comprehensive Output Protection
Outputs are protected against short circuits and overloads through thermal shutdown, with integrated protection for switching inductive loads and reverse polarity protection for the output power supply. Output monitoring with 10 ms delay provides diagnostic feedback .

Hazardous Area Certified
The module carries ATEX Zone 2 and Class I, Division 2 certifications, making it suitable for deployment in hazardous industrial environments where explosive atmospheres may be present .

Seamless Automation Studio Integration
The module integrates natively into B&R‘s Automation Studio software environment, enabling centralized parameter configuration and real-time data synchronization through the X2X Link bus system .

Application

The B&R X67DM1321 is deployed across industrial automation scenarios where flexible, field-level I/O is required:

• Cabinet-Free Machine Design: Ideal for modular machinery where control cabinets are eliminated or minimized, allowing I/O modules to be mounted directly on the machine frame .

• High-Speed Counting Applications: The 50 kHz event counters support tasks such as production counting, speed measurement, and position detection in packaging and material handling systems .

• Harsh Industrial Environments: With IP67 protection and ATEX Zone 2 certification, the module is suitable for food and beverage processing, pharmaceutical manufacturing, and chemical plants where washdown or hazardous conditions exist.

• Distributed I/O Architectures: Deployed as part of an X2X Link network, the module enables distributed control architectures that reduce wiring complexity and improve system scalability.

• Gate Measurement Tasks: The dedicated gate measurement input supports applications requiring precise pulse timing analysis, such as valve control or synchronization tasks .
