X20SP1130 B&R X20 System Safe Power Supply Module

Product Overview

The X20SP1130 (X20SP1130) is a high-performance safety power supply module from the B&R X20 System, specifically designed for safety-critical industrial applications. This module provides a single safe Type B1 digital output with a substantial 10 A nominal current capacity at 24 VDC. Engineered for use in functional safety circuits, the X20SP1130 acts as a reliable power source for safe I/O groups, allowing for the controlled and safe disconnection of potential groups within the X20 rack. Its Field Effect Transistor (FET) design features dual positive switching, ensuring a high level of diagnostic coverage and fault tolerance. By enabling the output level to be readable by the system, it provides engineers with real-time feedback for sophisticated safety monitoring and diagnostic routines.

Technical Configuration

The X20SP1130 is characterized by its "Type B1" safe output architecture, which operates without OSSD (Output Signal Switching Device) signals, making it ideal for specific safety potential group configurations. The module utilizes a dual positive switching FET variant, which provides redundant paths for power interruption, a fundamental requirement for high-level safety performance. A critical integration note for this module is the requirement to verify the list of permitted modules within the potential group it supplies; this ensures that all downstream components are compatible with the safe disconnection logic. The hardware is designed for industrial durability, maintaining a wide humidity tolerance of 5% to 95% across operation, storage, and transport phases.

Technical Specifications

Technical FAQs

What is the significance of the "Type B1" designation for this safe output?

Type B1 refers to a specific safety characteristic in B&R systems where the output is intended for the safe supply of potential groups. It indicates that the module can safely shut down power to a group of standard or safety modules, provided they are on the permitted compatibility list.

Why is the "Output level readable" feature important in a safety module?

This feature allows the safety controller to verify the actual state of the 10 A output against the commanded state. This diagnostic feedback is essential for detecting cross-circuits, external voltage feed-ins, or internal hardware failures, thereby increasing the overall Safety Integrity Level (SIL).

Does this module require a specific terminal block?

Yes, like all X20 modules, the X20SP1130 must be used with the appropriate X20 terminal block and bus module. The high 10 A current rating requires that the wiring and terminal block are correctly rated to handle the thermal load during continuous operation.

Engineering & Installation Guide

Potential Group Planning: When designing the safety circuit, refer to the official B&R "List of Permitted Modules" for the X20SP1130. Only compatible modules should be placed to the right of the SP1130 in the potential group to ensure that the safe shutdown signal is correctly propagated and that no unsafe modules compromise the safety function.

High-Current Thermal Management: With a 10 A nominal output, the X20SP1130 can generate localized heat. Ensure the X20 rack has adequate ventilation. When multiple high-power modules are installed side-by-side, it is best practice to calculate the total power dissipation and ensure the cabinet ambient temperature does not exceed the operating limits (typically 55 deg C to 60 deg C for X20 systems).

Wiring for Safety: Use 2.5 mm² (14 AWG) or larger wire for the 24 VDC supply and safe output connections to minimize voltage drop and prevent terminal overheating. Given the lack of OSSD, ensure that the external safety logic and feedback loops are correctly configured in the B&R SafeDESIGNER environment to maintain the intended safety category (e.g., PL e / SIL 3).
