Description

B&R 5AP981.1505-01X20 system high-performance power module

Overview

B&R 5AP981.1505-01 is a high-performance system power module designed by B&R Automation (now a brand under the ABB Group) for its X20 distributed I/O system. This module does not power the field equipment. Instead, it provides a stable, reliable and isolated working power supply for the backplane bus (X2X Link) of the entire X20 site and other I/O modules, communication modules and controllers installed on the substrate.

It is the “heart” of building the X20 control station, providing an energy foundation for all electronic modules. Its performance and reliability directly determine the stable operation of the entire I/O station and even the control system. This model is a compact power module with a rated output power of 15W and an output voltage of 5V DC.

Core features and advantages

1. High performance and high power density
Adopting efficient switching power supply technology, it provides a stable output power of up to 15W within a compact size, ensuring sufficient power supply for the X20 site connected to multiple modules.

High efficiency means low energy consumption and low heat generation, which helps to enhance the overall reliability of the system.

2. Wide input range and excellent adaptability
It supports a wide input voltage range (typically 19-29 VDC), capable of adapting to common voltage fluctuations in industrial environments, ensuring stable output and preventing system failures caused by unstable power supply.

This design enables it to directly use standard 24VDC industrial power supplies and is easy to integrate.

3. Comprehensive security and protection functions
Electrical isolation: There is an electrical isolation of up to 1500V AC between the input and output as well as between the output and the backplane, effectively preventing high voltage from intruding and damaging the expensive I/O and controller modules at the back end, ensuring the safety of the system and personnel.

◦ Multiple protections: Built-in overvoltage (OVP), overcurrent (OCP), and short-circuit (SCP) protection functions. When abnormal situations occur, the module will automatically shut down the output to protect itself and the subsequent circuits, and will automatically resume after the fault is eliminated.

◦ Reverse polarity protection: Prevents module damage caused by incorrect input power wiring.

4. Seamless system integration and hot-swapping support
Designed specifically for the X20 system, it can be easily plugged into the dedicated power slot on the X20 substrate.

It supports hot-swappable functionality, allowing power modules to be installed or replaced without power interruption to the system, which greatly enhances the system’s availability and maintainability, achieving true uninterrupted operation.

5. Condition monitoring and Diagnosis
It provides LED status indicator lights to display the “ready/faulty” status of the power supply in real time, facilitating quick diagnosis of the system power supply health.

Typical application fields

This power module is a core component of any control station based on the B&R X20 system and is widely used in:
• Machine automation: Distributed I/O stations for packaging machinery, plastic machinery, and printing machinery.

• Process automation: Remote I/O sites in process control cabinets.

• Energy management: Data acquisition unit in the power monitoring system.

• Transportation: Control subsystems for rail transit vehicles.

• Any field that requires high reliability and distributed control.
