B&R X20PS2100 X20 Internal I/O Power Supply Module

Product Overview

The X20PS2100 (X20PS2100) is a high-performance power supply module engineered for the B&R X20 System backplane. This module is specifically designed to provide the internal supply for the I/O power bus, serving as the electrical foundation for downstream digital and analog modules. Operating on a nominal 24 VDC input, the X20PS2100 features a wide tolerance range (-15% / +20%), ensuring stable system performance even in industrial environments prone to voltage fluctuations. With integrated status indicators for real-time diagnostics, this module minimizes troubleshooting time and prevents costly system downtime by ensuring the I/O bus remains powered within strict operational parameters.

Power Management and Diagnostic Logic

The X20PS2100 acts as the gateway between the external power source and the sensitive internal I/O circuitry. Its architecture is focused on electrical stability and preventative monitoring.

• Internal I/O Supply: This module feeds the internal supply lines of the X20 station, allowing a segment of I/O modules to function without overloading the CPU's primary power capacity.

• Visual Diagnostics: Features front-facing status indicators for "Operating State" and "Module Status," allowing field technicians to instantly verify power health without external meters.

• Input Resilience: Designed to handle an input range of 20.4 VDC to 28.8 VDC, making it compatible with various global industrial power standards and battery-backed systems.

Technical FAQs

What is the primary function of the X20PS2100 within an X20 station?

The X20PS2100 is used to "refresh" or initially supply the I/O power bus. If the cumulative power consumption of your I/O modules exceeds the capacity provided by the bus controller, this module is inserted to provide additional current to the segment to its right.

Why is a 10 A "slow-blow" fuse specified for the input?

Industrial power supplies often experience inrush current upon startup. A 10 A slow-blow fuse prevents nuisance tripping during the initial charging of the module's internal capacitors while still providing robust short-circuit protection for the system.

Can this module provide power to the X2X Link (Communication) bus?

No. The X20PS2100 is dedicated to the internal I/O supply. For powering the X2X Link communication bus, a specialized bus controller or a dedicated communication power supply module must be used.

Field Engineering & Installation Guide

• Potential Grouping: Use the X20PS2100 to create independent potential groups. By placing this module in the middle of a rack, you can isolate the power supply of a specific group of modules (e.g., isolating sensitive analog inputs from noisy digital outputs).

• Wiring Integrity: Ensure that the input power cables are sized correctly for the 10 A capacity. Use high-quality ferrules to ensure a gas-tight connection at the terminal block, preventing resistive heating at the power entry point.

• Thermal Consideration: Although the module is highly efficient, multiple power supply modules in a single rack can generate significant heat. Maintain the standard vertical orientation to allow for natural convection through the X20 housing vents.

Engineering Advantages

The X20PS2100 is built for the rigors of heavy industry. Its wide input voltage tolerance makes it an ideal choice for mobile automation and maritime applications where engine-driven alternators can cause voltage swings. The 5.0 kg shipping weight (reflecting the robust protective packaging required for sensitive power electronics) ensures the module arrives in factory-calibrated condition. Native integration into B&R Automation Studio allows for software-based monitoring of the module status, enabling proactive maintenance alerts before a power failure impacts the entire production line.
