XSC Safety PLC and XSR Safety Relays for Industrial Protection

The Beyond X Safety Solution by LS ELECTRIC addresses the requirement for high-integrity protection in modern industrial machinery. Designed for automotive and general manufacturing applications, the system utilizes the XSC Safety PLC and XSR Safety Relays to monitor safety devices and disconnect power before hazardous conditions lead to accidents. These components are engineered to meet SIL 3 and SIL CL3 safety levels under IEC 61508, as well as PLe and Category 4 standards under ISO 13849-1. By adhering to these international safety ratings, the platform allows engineers to maintain compliance across various regulatory environments using a single technical architecture.

Integrated Control via XSC Safety PLC
The XSC Safety PLC serves as a stand-alone controller characterized by high-density input and output configurations within a compact housing. The unit features 16 safety inputs and 4 Output Signal Switching Device outputs, supplemented by 4 dedicated feedback and restart inputs. This configuration enables the monitoring of external contactors and multiple safety zones from a single hardware point. By consolidating these functions into one device, the controller reduces the reliance on multiple individual relays, which minimizes the physical footprint required within control cabinets and simplifies the wiring architecture for complex machinery.

Logic Configuration and Diagnostic Mechanisms
Logic development for the XSC controller is managed through the XSC Safety Designer software. This environment utilizes a graphical interface with logical function blocks and a built-in simulator, allowing for the verification of safety logic before physical deployment. To maintain operational reliability, the hardware includes integrated diagnostics and short-circuit monitoring via four test outputs. These mechanisms detect electrical faults and wiring issues during operation, preventing unexpected system failures and ensuring continuous monitoring in demanding production environments where downtime must be minimized.

Modular Hardware and Environmental Durability
The XSR Safety Relay family provides modular, hardwired safety options to complement the programmable controller. The range includes feedback input relays, OSSD output devices, and multi-functional relays, all operating from a 24 VDC supply. To accommodate diverse installation requirements, both the PLC and relays are available with screw or push-in terminal blocks. The hardware is designed for high durability, featuring resistance to shock and vibration while maintaining a low-noise profile suitable for sensitive industrial settings. This modularity allows for the integration of safety functions into both new system designs and existing machinery retrofits.
