Schneider Electric — Safety Relays
The Schneider Preventa XPS series is a comprehensive modular safety relay portfolio designed for complete machine safety function coverage in a single consistent platform. Each module is dedicated to a specific safety function – emergency stop (XPS-EM), guard monitoring (XPS-GU), light curtain (XPS-LC), or two-hand control (XPS-TH) – with pre-configured internal logic per ISO 13849-1 and IEC 62061. Coded sockets physically prevent incorrect module types from being inserted into wrong base locations, eliminating a common source of wiring errors during commissioning and maintenance. All modules feature detachable screw terminal blocks for pre-wiring during panel assembly, reducing installation time by up to 50%. The series achieves SIL 3 / PL e / Cat. 4 across all functions with automated diagnostic coverage exceeding 99%, providing auditable safety integrity for machine certification and regulatory compliance in South African manufacturing facilities.
