X20PD2113 B&R X20 Series 6-Channel Digital Output Module

Product Overview

The X20PD2113 (X20PD2113) is a specialized digital output module within the B&R X20 system, designed for high-performance switching in decentralized automation architectures. Unlike standard source modules, the X20PD2113 features 6 digital outputs utilizing sink connection technology. This configuration is essential for interfacing with specific industrial actuators and electronic loads that require a ground-switching (NPN) logic. Engineered for the 24 VDC signal environment, this module provides a robust solution for machine builders in the printing, textile, and electronics assembly sectors where precision timing and specific electrical compatibility are required to maintain high throughput and minimize operational latency.

Technical Configuration

The X20PD2113 hardware is built to provide maximum electrical reliability across its 6 output channels. In a sink configuration, the module acts as a switch to the negative potential (0 VDC), allowing current to flow from the load through the module to the common ground. This is a critical requirement for integrating the B&R X20 system with third-party sensors or specialized valve manifolds that operate on NPN logic. Each channel is designed to handle a 24 VDC signal supply, and the module integrates seamlessly with the X20 backplane, providing real-time diagnostics to the central PLC. This allows for immediate detection of communication loss or power supply fluctuations, ensuring that the safety and logic integrity of the system remain uncompromised.

Technical Specifications

Technical FAQs

What is the primary difference between the X20PD2113 and a standard source module?

The X20PD2113 is a "Sink" module, meaning it switches the ground (negative) side of the load. Standard "Source" modules switch the positive 24 VDC side. You must ensure your field device is compatible with NPN (Sink) logic to prevent short circuits or non-operation.

How does the 6-output configuration affect the process image?

The module occupies a specific bit-width in the X20 process image. In the PLC configuration (Automation Studio), these 6 outputs are mapped to digital bits, allowing for direct logical control. Diagnostic bits are also available to monitor the internal status of the module.

Can I mix Sink and Source modules in the same X20 rack?

Yes. One of the primary advantages of the X20 system is its modularity. You can install the X20PD2113 alongside source modules, analog modules, and safety modules on the same backplane, provided the total power consumption does not exceed the limit of the power supply module.

Engineering & Installation Guide

• Sink Logic Wiring Safety: When wiring the X20PD2113, remember that the load is always "live" (connected to 24 VDC) and the module completes the circuit to ground. Ensure that the field wiring is properly insulated, as a stray wire touching the cabinet frame could inadvertently energize the actuator by creating an accidental path to ground.

• Backplane Power Calculations: Before adding multiple X20PD2113 modules to a single bus segment, verify the current requirements for the internal X20 bus. If the total internal consumption of the I/O modules exceeds the capacity of the Bus Controller, an additional X20PS (Power Supply) module must be inserted to boost the backplane power.

• Interference Mitigation: Since sink outputs are often used with high-speed electronic components, ensure that signal cables are kept away from high-power AC lines. Use shielded cables if the module is switching at high frequencies to prevent electromagnetic interference from affecting neighboring analog signals or communication lines.
