X67PS1300 B&R X67 System Power Supply Module

Product Overview

The X67PS1300 (X67PS1300) is a high-performance power supply module from B&R Industrial Automation’s X67 system, designed specifically to provide an electrically isolated power source for the X2X Link bus. This module is a critical infrastructure component for decentralized I/O architectures, ensuring that the communication link remains stable and protected from potential ground loops or electrical interference originating from the field side. The X67PS1300 features integrated diagnostics through clear status indicators for both input and output voltage levels, allowing maintenance personnel to quickly verify power health at a glance. Its compact, rugged design makes it ideal for direct machine mounting in harsh industrial environments where space is limited and reliability is paramount.

Technical Configuration

The X67PS1300 is engineered for seamless integration into the B&R X67 I/O system. It functions by decoupling the internal system supply from the incoming field power, providing a clean and isolated 24 VDC supply to the X2X Link. This isolation is vital for maintaining signal integrity over long distances and across multiple remote I/O nodes. The module’s hardware includes two status LEDs: one indicating that the "Input voltage" is within the tolerance range, and another confirming the "Output voltage" is active and ready. With a very low internal power consumption of only 3 W, the module operates efficiently with minimal heat generation, which is essential for high-density DIN rail or panel installations.

Technical FAQs

When is it necessary to add an X67PS1300 to an X67 I/O segment?

An additional power supply module is required when the total power consumption of the connected X67 modules exceeds the current capacity provided by the bus controller, or when electrical isolation is needed to segment the bus for noise reduction.

Can this module power 24 VDC sensors and actuators directly?

No, the X67PS1300 is specifically designed to provide isolated power for the X2X Link communication bus. Field devices (sensors/actuators) should be powered via the standard I/O module power pins or a dedicated field power supply.

What does it mean if the "Output voltage OK" LED is off but the "Input" LED is on?

This indicates an internal fault or an overload/short circuit on the X2X Link side. Disconnect the downstream X2X bus cables and check for shorts or excessive current draw from the connected I/O modules.

Engineering & Installation Guide

X2X Link Grounding and Shielding: To ensure maximum interference immunity, the X2X Link cable must be properly shielded. When installing the X67PS1300, ensure that the shield is connected to the functional ground (FE) at the module's mounting point. The electrical isolation provided by the PS1300 will prevent ground loops between different machine sections.

Thermal Considerations: Although the internal power consumption is low (3 W), B&R recommends installing the module vertically to facilitate natural convection. Avoid placing high-heat-generating components (like motor starters or large power supplies) directly beneath the X67PS1300 to prevent thermal stress on the diagnostic electronics.

Safe Termination: Before connecting or disconnecting the X2X Link cables to the X67PS1300, always ensure the input power is switched off. Plugging the module into an active "hot" bus can cause communication transients that may disrupt the synchronization of the PLC cycle or cause temporary bus errors in the X67 network.
