Siemens Safety Relays

Siemens Safety Relays prices and range: 29 models with current prices, stock status and specifications at Welibaba. A safety relay is a control device that monitors safety elements such as emergency stop buttons, light barriers and door switches with redundant circuits and safely cuts the machine's motion in a hazardous situation. It is used to implement the safety function required by the risk assessment on machines where the operator can reach the hazardous area, such as presses and robot cells. The category includes Siemens 3SK1 and configurable 3SK2, Schneider Electric XPS and ABB safety relays and expansion modules; the product data lists models rated Category 4, SIL 3 and PL e, and types with delayed outputs. Choose the relay according to the performance level (PL) or SIL value resulting from the risk assessment, the type of safety element to be connected, the number of safe outputs, the reset method and the supply voltage. The performance level is determined under EN ISO 13849-1 and SIL under IEC 62061, and the assessment covers the entire safety chain. A standard control relay is not a substitute for a safety relay because it does not have a redundant structure that monitors its own faults.
